X500 - Feels like hard shell

Overall, I was happy with my purchase and the kayak feels sturdy, stable and tracks well almost like a hard shell kayak. I would recommend it. Feel: It feels like a hard shell kayak on the bottom and sides (not top). I don't notice any flexing. Like a SUP you can literally stand up on on. Stability: It's quite stable. However if you are a beginner it may feel a bit unstable until your skills improve. For anyone else who has owned sea kayaks or smaller this is a great. This is a V bottom kayak which is impressive for an inflatable. I would have been happy with an inch narrower. Tracking: It tracks well but without a rudder there will always be minor corrections when you stop padding. In other angles it tracks like any other sea kayak depending on the wind and waves. In the waves: In 2-3 foot waves and heavy boat traffic it feels safe. When the waves come up behind you, which you normally have to watch for anyways, the nose does stays up since there is a lot more volume up there. What can be improved. 1 - The seat is hard both on the bottom and back. I had to put 1/2" pads on both. There is excellent back support but you have to pad it. 2 - The weight is a bit at 40lbs. Not something I carry on my back (I'm 150lbs). The way the straps are setup there is too much weight on top. So i just cart it. So in short, pls add wheels to the case like the double. 3. Considering the performance aspect of the kayak, there is limited support for your knees if you're trying to angle the kayak (The top is a cover and not hard). I would have definitively added straps for the knees against the bottom for those times I'm in waves and want more control (feature request). 4. The Canadian site did not have the spray skirt for sale which is unfortunate. The rim of the cockpit is "a hard rubber ring" but it can't take as much pull as a hard shell. Additionally, you need a thin rim on the spray skirt otherwise it will not get under the lip. For the moment I'm using a cheaper nylon skirt that leaks but keeps me mostly dry.

Very happy with the tradeoffs this kayak

There are a lot of things to be loved in this kayak, and there are also a few tradeoffs. Stability : this kayak is tippy, but I didn’t find this as problematic as other people did and could manage it pretty quickly. To me, the hardest is to get in and out from a pier, but still very doable. The bright side is that this kayak is as fast a normal hard shell one, thanks to the V shape haul and the high pressure of the chambers. Compared to my previous very stable inflatable kayak, I probably go twice as fast. As others stated, not inflating the main chamber to the max 10 psi also helps to lower the learning curve. Portability : the bag is a bit bigger and a bit heavier than I first tough. It does fold easily and the compact storage size is clearly a big positive point. The bag is big enough to add the pump, the paddles and a PFD. But getting around with it, if you don’t have a car, isn’t as convenient as I wished. I am able to bike with it on my back, but I do recognize that not everyone will be able to sustain such a weight on long distances. If you have a car with a few passengers, the main issue will be the space it takes in your trunk. Durability and price : at this price, I do hope to keep this kayak for a few years. The quality and the material seems nice, which is the same then the paddleboard decathlon sells. Others : I wish this kayak had a watertight compartment like most hardshell kayaks offers, but the back part isn’t close from the cabin, so water get in if you aren’t using a skirt. You might want to buy a waterproof bag. Also, at that price point (which makes it one of the most expensive options), I would have found it nice to include a paddle, the skirt and/or the pump, which aren’t. Conclusion : if portability, storage and performance are your main criteria, I truly believe this product is a game changer and absolutely value the high price. If you are beginning in Kayaking, maybe you would prefer to check a cheaper and more stable option. If portability and storage are no issue, then a hard shell kayak is probably still better for you until the price of those goes down. I am still giving 5 stars because this product is totally fulfilling my needs.

For sports, not for touring, bad valves

Valves difficult to operate, the advantage of quick filling lost. No stability, you keep you balance with the paddle and going fast. Stop to take photographs and you end up swimming with your camera. No straps to secure the paddle. I don't find the cayak heavy compared to others. The technological innovation is good, but they need to find better valves and make a touring version with better stability. Now you cannot let your friends try it or it will end up bad.


We are sorry that the experience with this kayak was not really positive. We work hard to offer our sportsmen and women quality products and your feedback will help us to improve the quality of this product. 
To improve the stability of your kayak, you can inflate the bottom to 5PSI instead of 10PSI it will naturally flatten, the kayak will be deeper in the water, therefore more stable. It is also possible to load the kayak so that it sinks deeper.
We hope to see you soon at Decathlon.
Best regards,
Team Decathlon
She's Stable... UPDATE

In my first review of this Kayak I said the one thing I had a problem with was that the Bag was a bit small. However, I can now take that back as I found out if you simply use a second strap a round the Yak before you place it in the bag then it fits with ease. Such a shame the Yak only comes with the one orange strap to hold it together when packing a way, because using a strap at the top and one at the bottom makes it fit the bag so well.

Itiwit x500

Inflates in 2 minutes due to the high pressure pump and fits nicely into the carrying rucksack following deflation. In fact the pump, seat and foot pegs also fit inside with the paddles slotted in the pouches. Glides beautifully and is very responsive. I am a relative beginner to this activity and have read some reviews describing the kyak as " tippy"- I would suggest responsive is a better description as with your feet and knees anchored you can get a feel for the craft. Same with many activities, the more you practise the luckier you get!

Excellent Inflatable Kayak

Firstly I would like to thank the staff at the Tamworth store for their help and knowledge. After much research and consideration of various rigid kayaks and inflatables, for a variety of environments; I decided that the X500 single kayak would fit with my requirements. I am over seventy, so lifting kayaks onto roof racks can be a bit arduous. The cockpit on the X500 is plenty big enough to give easy access and egress. When paddling it tracks well and feels quite fast, although I haven't measured the speed over flat water with no wind as yet. I tried the spray deck and found it fitted well and was easy to put on, even though it was new. I haven't had any problem with it being unstable. I did try some support strokes with the spray deck on, to see how far I could tip it and it seems fine. However, I personally would like some hip pads, if they could be made to fit. Inflation and deflation is straightforward as is packing away following a little practice. I would certainly recommend this kayak for anyone who wants something in which to enjoy a variety of waters.

I never write reviews but………

I never write reviews however I just wanted to congratulate ITIWIT on making such a great product! I’ve owned various inflatables and a hard shell in the past. The difficulty I had with the hard shell is portaging and with inflatables either setup time or just being so inefficient in the water. For me, this is the perfect all rounder. I’ll explain……. In terms of setup time it took me just over 10 minutes on my first attempt. I actually felt a bit nervous after reading the reviews of tippiness but was surprised on how stable it is, no more tippy than my hard shell (note I have the V2 x500 model). Now don’t get me wrong, if someone has never kayaked before they may feel it’s a bit tippy, but this is because they are not used to kayaking and this is something to get used to. On the water it’s a breeze and quite fast. Tracking is good. The seat is comfortable enough with good lumber support. I used the ITIWIT split carbon paddle which is very good for the money. The paddle is not the lightest but is light enough and gives no blisters. In terms of portaging it couldn’t get any easier. The kayak can be lifted out of the water with one arm. I popped it on my shoulder and comfortably walked to the next portage point. Putting the kayak back in the water is easy and getting back in felt more stable than my hard shell. Overall I’d say it’s the perfect balance between weight and speed, not as fast as a hard shell but lighter and faster than other inflatables. It sits more into the water making it less susceptible to wind and feel more like a kayak. It just made a day out, quick easy and stress free. And back at the car it was all packed away in 10 minutes. This kayak is in my opinion very good value for money. It is cheaper than other premium inflatables and most hard shells. If someone is looking for a good all rounder then this ticks all the boxes at an affordable price.

Satisfactory multifunction touring kayak

Recently purchased as I prefer to use public transport and for stowage on a yacht. Having read the reviews and watched countless YouTube videos (in all languages) it looked like the right boat. I must say that anyone with some kayaking experience that finds this too unstable is doing something wrong. This boat is very stable in a fast flowing river and can handle a moderate sea state well. I am quite used to racing kayaks (K1&K2) so my stability is fairly good in quite/very ‘tippy’ boats; however I think it is being very unfair to call this boat unstable. Floor pressure range from 7-10 psi makes this a very stable boat depending on conditions. You do not have to paddle to remain upright, resting it is quite easy and no need to brace with the paddle either. I purchased it in 2021 so I guess it is the most recent version. Having done lots of different types of kayaking in the past I would still consider my ability to be intermediate at best. It is easy to handle and is easy manoeuvre, I haven’t rolled it yet, so the verdict is out on that one for the moment. It’s comfortable to paddle for long distances and holds enough kit for a 2-3 day river/sea trip. Setup is easy, folding takes a little practice to get right. Overall I am very impressed with this boat and it has easily taken over as my primary multifunction touring boat. It’s not a racer, whitewater play boat or slalom boat, but that’s not what it’s for. If you are touring in rivers or the sea then I fully recommend it and I even think it paddles reasonably well as a whitewater racer (with a little extra buoyancy stuffed in the back). It doesn’t perform like any of my specialist rigid boats but they are all one trick ponies, and can’t fit on a train easily. Good work Decathlon!

Hello Steve, thank you for reviewing our dropstitch inflatable kayak. We are really happy to hear that you are enjoying using it and the overall experience is good.

Thank you and we hope to see you in the store soon.

One of its kind!

I've had this kayak for a while now but only managed to unfold it and leave it inflated for a day so far (to make sure everything is fine) but I can already see it's going to be fantastic experience on the water. It looks great as it's the only sit-inside full drop-stitch kayak on the market. It feels really sturdy so I just look forward to spring time now. The only 2 things I have to point out: availability of the matching Itiwit spray deck - with such a great craft, I wouldn't like to use 3rd party ones. Please, bring it back to your offer. Second thing is the paddle - such a good craft needs a proper full carbon paddle to maximize the experience. Maybe even one with wing blades? Everything else is absolutely outstanding and I'd love to see Decathlon/Itiwit expanding their offer by adding more good looking, high performance full drop-stitch kayaks to the catalogue (a recreational and a racing/surfski perhaps? A high pressure surfski would be a real achievement).

Despite several negative reviews, I decided to try this kayak. I am amazed - this is easy to carry, the bag is one of the better carry bags I have seen; the kayak is unpacked and inflated in 5 minutes. The footrests install quickly, and then you are on the water. It is a lightweight kayak to carry to and from the water. Once it is on the water, I found this kayak very stable and comfortable to paddle - it is more stable than some rigid kayaks I have tried.It is fairly quick on the water, and turns easily; in a fairly strong wind, I found the tracking to be acceptable. My wife, who has never kayaked until a week ago, tried this out and paddled a mile or so with no problems, and commented that is was easy and comfortable. All in all a great kayak, and a great buy.

Love this kayak

I’ve used inflatable kayaks before but this one is sooo easy and manageable as it glides through the sea! I loved it. I’ve yet to experience rough seas but it is so comfortable and I just let part of the sea. Easy to disembark and get back in.

Stable enough

Well I am not the most balanced or coordinated so I took this out on Sale waterpark first time and I love it. It does have a more boat shaped hull so feels at first like your on a bit of a knife edge, then it's significantly wider and flatter in the center which does hold you. A bit like it has two tipping points. I held onto the quayside and tipped to the capsize point and found it to be when the water is at the edge of the deck. I would have to throw myself pretty hard to one side to actually capsize; so I find the capsize tales a bit silly really. I have no great experience. A bit of paddling with the sea cadets 40 + years ago. Of course you can sit in it!! Handles beautifully, like I remember a solid kayak. Amazing to me that this level of feel and performance can be achieved with an inflatable. I wonder how it will cope with constant folding / unfolding, but so long at it holds air, I think we have to be realistic. It is heavy, about the weight of a very full very large suitcase. No way you will be hiking and paddling. My partner thought that made it less accessible for many women ie getting it on her back at all, which I think is a fair point. Some suitcase wheels on the base of the case might be a worthy improvement? Amazing craft though, looking forward to many happy hours in it!!

Perfect for river paddling

I love mine. This was my 2nd kayak, coming from an ultra-stable flat-bottom inflatable. Sure, it's a bit tippy but some of these reviews are ridiculous.Within an hour I was comfortable paddling it, edging it for tighter turns and balancing it without paddling. No idea why "experienced paddlers" post bad reviews of this for being too tippy - it's a joy to control when you get used to it and works great with a greenland paddle too. I've yet to take it on tidal water but absolutely will be doing so soon.

An absolute pleasure

I have had the Kayak for two weeks now and taken it out for 3 rides already and it is an absolute dream. I am a beginner in kayaking and initially it take a couple of paddle strokes to get used to it but I am over the moon with this kayak. I read a lot about the supposed instability, and yes it is not rock solid on the water like a paddleboard but for an inflatable kayak I have had no problems at all (been on Thames and surrounding tributaries). I am about 95kg and pumped the kayak to 10psi and it is all fine. Inflating the Kayak take 4-5 minutes - only 1 of 5 air chambers takes 3 minutes the rest is a few pumps only. It is easy to carry it to the water. Once in the water it tracks pretty straight and it is comfortable.

Great, stable and fast!

Honestly I don't understand all these complaints regarding the stability of this kayak. Capsizing after 10m? Really not sure what to say... I've been using this kayak for more than year, at the moment using it pretty much every week on a river (Thames), did also many lake trips with camping etc. Taken it couple times to the sea. All I can say is that this kayak is an absolute rocket, the performance is great, I could easily compete with my friends in the rigit kayaks and even beat them many times due to V-shape of this kayak. Yes, it doesn't feel as stable as flat, sit on top kayak but it really needs a couple minutes to get the balance and get used to it. I have never ever capsized, neither any of my friends that wanted to try it or even people that did the kayaking for a first time in their life! And yes, it's worth to fine the best pressure to pump it up to, based on the weight and additional load, that can help a lot. However, I did most of my trips with the recommended pressure (10bar) and no load and I'm just about 55kg and it was absolutely fine. If you look for kayak that is easy to transport, easy to assemble, has a great performance and looks absolutely great, then I highly recommend this one.

An innovation, and a patent pending!

The initial idea? Design our dream kayak: a high-performance inflatable kayak that you can take everywhere with your backpack, in short: Freedom! To do that, 30 months of design and development, 7 prototypes - which we call "monsters" here - were necessary. The main challenge:to add rigidity, performance to an inflatable kayak. And so we have patented the unique cutting and assembly of the materials used.

Why a rigid inflatable kayak?

"We listened to the kayakers:""I have a good level in kayaking and I want an inflatable kayak that has the same performance as a rigid kayak"", ""I want to go kayaking using public transport."", "" Inflatable kayaks are nice but I want a kayak that is goes fast!"" It was therefore necessary to design an easily transportable and efficient kayak, in short innovative."

Marc ronet, naval architect tells us about the adventure with decathlon:

"My work involved defining the overall geometry of the kayak, its general balance. When the Itiwit team called me, I was surprised but very interested. And it was also thanks to our common passion for kayaking. We were able to share our respective knowledge. It's been a great experience!"

Why the name "kayak x500 dropstitch"?

"Dropstitch" is a material. 2 layers of PVC are connected by thousands of nylon threads. When inflated to high pressure, these threads tighten and create a rigid volume, which prevents the kayak from loosing its shape. This is what makes our inflatable kayak extremely rigid but easy to store in a backpack once deflated."

How was the design worked?

A real teamwork with the engineer, the architect and the product manager. Emmanuelle designed the product based on its technical constraints. We can speak of functional lines. The dark gray corresponds to the paddling area, light gray for the loading area and orange for visibility.

How to inflate and mount the kayak?

"1. 1. Inflate the main chamber (floor), then the intermediate chambers (walls), followed by the small chambers (arches). All the volumes are inflated to 10 PSI max (0.7 bar). 2. You can insert the foot-rests on the flexible guides, push them inside the kayak, and adjust to your leg length with the buckle. 3. 3. Position the seat by fitting it onto the shims provided. 4. Position the backrests under the coaming. We recommend the HP Itiwit twin-action hand pump (8387655), not supplied."
