Questions & Answers

Look for product information, frequently asked questions, opinions...


What type of pressure valve does the Itiwit Adult X500 V2 Inflatable Kayak use for inflating? Thanks!


This kayak uses the High pressure Bravo valve. The same type you find on most of the SUPs.

What are the official X500 (V2 1-person) cockpit dimensions for fitting a spray skirt? Will Decathlon’s Itiwit X500 spray skirt be available in the USA?


Yes our Itiwit spraydeck will be back in stock within 3 weeks. The dimension is what we called "Standard big deck" all big deck spraydeck will fit.

By Yann on Sep 18, 2023 | STAFF


The material is listed as "PVC." Is there a denier rating associated with the kayak material? I'm curious about the kayaks durability in shallow water with rocks and submerged logs. Thanks!


There is no denier rating for PVC as it is not textile but Vinyl. There will be no problem with logs and rocks as long as they are not sharp.

Is The spray skirt for the 500 back in stock? If so save one for me thanks. Larry.


Stock is available ref 8801423 KAYAK SPRAYDECK X500.

When will the new model of the Itiwit x500 be available for purchase?


Unfortunately, we will no longer be selling our kayaks in the USA. We won't have the new Itiwit X500 kayak.

Out on the water

Makes a lot of fun

Deteriorated quality

We are on the fourth kayak. I purchased the first one in 2022, with production done in 2019. I have already commented on the truly enviable characteristics of this kayak. But it began to show defects so I had the scruple to do a service check, and upon return I received the kayak damaged in transport. From that moment on, a disaster. First replacement, kayak unpacked, repackaged in 20 minutes and returned, due to folds and various defects, with damaged fabric (and defects of my old kayak already present when new, even more extensively). Second replacement, similar fold conditions but without absurd damage (I accepted the compromise, despite reporting the matter, fearing an ordeal). both kayaks produced 2021 After months, first test where the sea even worsened following wind conditions, and a problem I encountered became very annoying and dangerous in that condition: to go straight I had to paddle only on the left. On land I realized that the kayak was clearly crooked and badly glued, it was curved to the left, and at sea it tended to veer a lot to the left. Replaced after inspection in the laboratory which confirmed the obvious manufacturing error, the fourth kayak arrived today. The material has deteriorated in quality a lot. production is June 2022. I am encountering problems and I notice that the material is similar to the many with leakage problems seen around, which suffer a lot from plastic fatigue when bending. It has worse defects than the last one I received, but not worse than the second one I received. It has a little misalignment of the bow and stern (stern on the left, bow on the right), but it is very plastic and full of creases, bubbles and defects. A very strong mistreatment is right on the backrest chamber, typical of countless models with leaks, never seen so mistreated (the others were perfect), and I want to add that, of the many models seen leaking there, one of these kayaks is the subject of one of the reviews done (the customer says he is on his third kayak, look at that). Having had kayaks from different eras (all V2 models anyway) I can say that the quality has dropped dramatically, bordering on intolerability. Or perhaps, tolerability. A shame, because there is no other product in the world with these characteristics and at this price. And the worst is that returning and asking for a definitive refund would be equivalent to having to keep on your back ALL the accessories purchased for several hundred euros (I would quantify that for the decathlon accessories alone, there are well over 350 euros of extra spending, including clothing, summer and winter equipment, basic equipment, such as paddles, emergency equipment, assembly equipment, etc.) Would I generally recommend the product? Yes. Would I recommend the product in its current state? Absolutely not. Valid product, if it were better looked after. Perhaps, the most valid that exists among the foldable dropstitch. Which makes me even more angry.

Solid kayak

Basically, I am happy with the kayak. There are only two things that bother me. 1. The seam under the kayak should not be glued in the direction of travel. The possibility that you brush against it while driving and the seam opens cannot be ruled out. 2. My kayak has a slight twist to the left and this affects the straight-ahead travel. Unfortunately, I have to adjust my seat/hip position and this feels uncomfortable after a while.

I'm satisfied

The product fits in the trunk. If it is on the back, I can walk for about 15 minutes. The installation is completed in 10 minutes. After use, rinse it with a wet cloth and dry it. If you deflate it with the help of a pump, you can easily put it back in its bag. It is very important to deflate it completely. Its speed is as good as recreational skis.

Top price/performance

I have been kayaking for around 70km over the last two months. On lakes with lots of wind and waves and on small, winding rivers. With good technique, the boat always travels straight and is forgiving of beginners' mistakes. As a beginner, I was surprised that I had an average speed of 4.9kmh over long distances (12km). On short distances, 7.5kmh was no problem.

I am happy :-)

My opinion is based on a 14 km paddle trip through the Rursee. I normally use a Prijon Dayliner. Setting it up was easy. Getting in was no problem either. The speed was comparable to the Prijon Dayliner. The X500 felt lighter, though. The straight line was good as long as you were paddling. You never missed having a steering system. Dismantling and packing it up wasn't an easy task, but that was probably my fault. Some reviews said that the boat capsized easily. That wasn't an issue on the Rursee, at least. The boat takes up a lot of space in the trunk. And the 20 kg have to be carried first. Overall, I'm very happy with the boat.

Skeg desperately needed

An intermediate kayaker, wanted an upgrade after 5 years using my Intex Excursion Pro on long distances in rough sea. Boy, it's fast..I felt a little bit unsure and afraid not to type, but this was not my main problem. It was impossible to paddle hard and keep it straight..Hard right, hard left, I was zigzagging and at some point running in circles. All the wonderful speed was wasted trying to correct my trajectory. I will try to stick one or two skegs, but the first impression is that somebody missed his physics lesson about weather cocking. Good points: -easy to inflate/ deflate - very, very fast - very good construction - very good and comfortable carry bag - good price/ quality Bad: -no pump/ paddle included - NO SKEG!!(not included, not even optional ). Very tricky to maintain trajectory in windy/rough sea conditions - the Itwit spray skirt is a nightmare to put in place, my fingers hurt - not the most spacious or easy to entry for a 190 cm person

Good product!

A top kayak!!

Really very happy with this kayak! It inflates in just a few minutes and is very light! I started with 100 inflation with the big tubes, and I absolutely don't regret having swapped for this one! A pleasure to paddle!

Itiwit x 500 1 person kayak

Can someone help as can’t get answer from decathlon. I’m yet to purchase the itiwit x500. Are the kayaks now the version 2 with the version 1 now discontinued ? Thanks

High-performance kayak for an inflatable

I bought the X500 used. I have been kayaking for 12 years (rigid deck and high pressure inflatable). Compared to other brands of inflatable kayak, it sets up very quickly. It is very rigid, relatively light and at sea it behaves very well as long as you have a minimum of practice. I recommend it to beginners with a bit of perseverance. The absence of a keel means that the X500 slides in side winds but this makes it playful and does not penalize it too much. Cleaning/rinsing the boat is a bit tedious because certain parts are difficult to access: the inside of the bow and the front part of the deck (at the elastics). Folding the X500 does not pose a problem except when temperatures are low: the plastic becomes rigid, the kayak is difficult to store in its bag. In the end, I don't regret my purchase, the X500 fulfills its mission perfectly for day trips. Attention !! (and it's regrettable): not all skirts fit this kayak and I had to buy the skirt offered by Decathlon.

This kayak (version 2) is definitely not a returner. If you have ever fallen on sea kayaks such as the Rainbow Laser Expedition and had no problems, you won't have them here either.

Completely meets my expectations, easy to set up and fold, very efficient for an inflatable.

What are the dimensions and weight?

”When the kayak is inflated:> length: 12'6”> width: 25.2”When stored in its bag:> height: 37”> width: 19.7”> thickness: 10.6”> full weight: 39.7 lbs (kayak itself 35.3 lbs)Hatch storage: 24”

An innovation, and a patent pending!

The initial idea? Design our dream kayak: A high-performance inflatable kayak that we can take with us everywhere with its backpack, in short: freedom! To get to this stage, 30 months of studying and developing 7 prototypes - which we call in our jargon a ”mock-up” - were required. The main challenge was: to provide rigidity and performance in an inflatable kayak. Which is why we patented the cut shape and the unique blend of materials we used.

Why a rigid inflatable kayak?

”We listened to 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!”So we had to make a high-performing kayak that was easily transportable. Innovation was the only option

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 Itiwit called me, I was surprised but very interested. I love kayaking, so we had that in common. We were able to build on our respective knowledge. It was an amazing experience!”

Why the name ”kayak x500 dropstitch”?

”The ”dropstitch” is a material. 2 layers of PVC are connected by thousands of polyester strands. When inflated to high pressure, these threads tighten and create a rigid volume, which prevents the kayak from loosing its shape.Which is what makes our inflatable kayak extremely rigid but easy to stow in a backpack once deflated.”

How was the design worked?

True teamwork between the engineer, the architect, and the product manager. Emmanuelle designed the product according to the technical constraints. We can talk about functional design. The dark gray corresponds to paddling zone, the light gray to the cargo area, and orange to visibility needs.

How to inflate and mount the kayak?

”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 footrests on the flexible guides, push them inside the kayak, and adjust to your leg length with the buckle.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.”

How to disassemble and deflate the kayak?

”You'll see it's quite simple!1. Make sure the folding surface is clean.2. Remove the seat.3. Remove the footrests 4. Deflate the kayak by removing the cap and pressing the valve. (Leave the valve in the open position for air to escape)5. Tuck in the hatch and start folding lengthwise.”

How to fold it up to put it in the bag?

”1. We recommend placing the canvas of the bridge inside the fold. 2. Fold the keel over its entire length. This fold ensures that the width of the kayak is the same as that of the bag.3. Fold each end toward the inside of the kayak and line up the ends with the Itiwit logo.4. Slot the seat in the last fold of the kayak and finish expelling air from the kayak by pressing on it.5. Finishing step: Strap the kayak (a good strap makes it easier to put it in the bag).”

Product testing

Our kayak is tested and approved by our internal and external ambassadors.Some examples? Nicolas traveled the Dordogne with this kayak: 81 miles in 1 dayFrançois went down the Danube from Ulm in Germany to Sulina in Romania on the Black Sea: 1,616 miles!Find their stories and our videos on the itiwit website.
