Awesome Commuter Backpack

This has exceeded expectations. It’s great for cycling and if it starts to rain, I don’t have to worry about the contents getting wet. The only downfall is no outer pocket but I understand why there isn’t one because then it wouldn’t be waterproof for all. I’ve just used my hip bag and clipped it around the bag as an outer pocket.

Great Value

This dry bag is really good for the money. It has basic features & seems to be of decent quality. My dry bags get a hiding in my small boats; bounced around, buried under heavy equipment, walked on - the works. After a few solid weeks of abuse it still looks pretty much new. I particularly like the internal pockets & the rigid top folds. The 20L is not really big enough for me. I wanted the larger 30L version with the outer zipper pocket but can’t do the blaze orange. Itwit please make it in black!

Overall good bag

This bag is great to keep stuff safe but it could be a little bit more practical. There is no way to adjust the clasp to close the bag. Meaning that if you have an article a little bit bigger you will not be able to close the bag.

So practical, and stylish too.

This is brilliant for swimming gear. So well designed, with lots of compartments for all your belongings. Big enough for everything. The designers should be applauded for such a practical item and the styling makes it look much more expensive than it is. Fantastic!

Good bag and definitely waterproof

I love this bag, it’s stylish and it does it’s job. The only thing I’d change is adding a few compartments. Once your stuff is inside it takes a while to get things out. I’m using it for general use on rainy days.

Good bag needs improvement though

The attachments to do up the bag are not adjustable so really hard to close up quickly on the water. Also the chest strap is not women friendly boobs get in the way. However, the actual bag is very waterproof

Waterproof bag

Brilliant bag for all seasons, especially with the British weather. Keeps everything dry, so spare clothes and important documents are completely safe and protected

Overall very pleased.

Can’t give more than good yet as it has so far only had relatively limited use. It if lasts well, and remains waterproof, then I would say excellent, but too soon for that.

Simply does the job with no fuss, a great product. Used and much admired by others

ITIWIT 20L watertight backpack

Quite simply, this is the best quality and value for money waterproof backpack on the market. I have a Patagonia and North Face - but this knocks the spots off them! If a larger (30L or 40L ) version is available, then you have an even better product!

Excellent bag for cycling

Perfect size for clothes, shoes and a laptop on my daily commute. Really comfortable straps and easy to fold. One addition that would be great would be a small exterior pocket for phone/wallet. Other than that it's incredible value when compared with other water-tight brands.

Good backpack but more sizes would be better

The backpack has a really good quality (e.g. comfortable shoulder straps, easy to use folding strap, pockets inside the backpack) however I returned it as it was too small after all. @Decathlon: Please make more sizes available! I would have preferred 30L or more.

Precautions for electronic devices

Electronic devices are fragile and valuable. We recommend doubling up their protection by putting phones in waterproof pouches inside dry bags. Cameras can be put in a small dry bag (5 L or 10 L) placed inside a large dry bag (20 L, 30 L, 40 L, 60 L). Ensure your bags are closed and check water resistance regularly before your session using a paper towel.

Fastening system

To ensure good water resistance: 1/ roll the top of the bag over carefully 5 times, folding tightly over the width of the strap 2/ fasten the central buckle 3/ fasten the side buckles Leave some air in the bag. The bag should appear inflated once closed: this makes it more watertight and allows it to float if dropped in the water.

Attachment on a stand up paddle or a kayak

The 2 compression straps on the body of the bag can be used to attach the backpack to an SUP or a kayak equipped with fastening loops, enabling you to carry your belongings into the water and protect them.
