I used this in Canyoneering in Cebu. It's so light and it has pockets inside. Highly recommended!!!
Good quality, standard IMO color
Brilliant bag for all seasons, especially with the British weather. Keeps everything dry, so spare clothes and important documents are completely safe and protected
It is large enough to put all my stuff and it's strong waterproof feature completely protects the things from water.
This product has very good waterproof feature that products inside will never get wet. It is also large enough to carry many stuffs to practice watersports or go to the beach.
Good Price, Good Quality
A4 pocket on the inside and the foam pads on for added comfort, allowed me to use it for both work and doing watersports. However, i have yet to test on how waterproof this bagpack is, but so far everthing inside was still dry in the rain. I would give it 5 stars if it had an added pocket on the outside so that i can put small essential things to retrieve it easily instead of having to opening and closing it from the main compartment over and over again. Overall great product!
I am happy with the material of the bag. Looks simple and easy to maintain. I even try to put it on a rocky surface and there is no sign of scratches. I use it for fishing. Just nice for this heavy rain. My items very dry inside the bag.
Thank you for your awesome feedback!
I'm glad you liked the product.
It is also one of our best sellers.
To add on, we will be bringing more waterproof bags next year, so stay tuned!
I hope to see you in stores soon!
Cheers and Best Regards,

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
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!
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.
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.
Bought this bag for my son who's cycling around Europe and Central Asia. It is ideal, very sturdy, waterproof and very reasonably priced when compared to alternatives.
I ride bicycle to/from work and pack my office clothes inside no matter the weather conditions may be (snow, rain or shine). I purchase previously the 16 liters Tribord waterproof backpack. That one is sometimes a little small during winter when I pack more layers of warm clothes, a pair of shoes and my tablet/laptop with its accessories. This 20 liters waterproof backpack can fulfill my needs for the winter rides, but I wish the following features could be considered: 1. Add an external waterproof pocket just like on the old 16 liters Tribord waterproof backpack, so that small items like keys or wallet can be quickly stored without reopening the whole backpack. 2. Add an adjustable cord on both side clips just like the 16 liters Tribord waterproof backpack. 3. Add an inner bottom and back cushion to protect items that are carried. 4. In addition to the chest clip, add a waist clip that can help to keep the backpack close to the body when running.

Electronic devices are fragile and valuable. We recommend doubling your protection by placing telephones in watertight pouches within the duffel bag. Cameras can be placed in a small duffel bag (5 L or 10 L) inside a large duffel bag (20 L, 30 L, 40, 60 L). Ensure your bags are closed and check water resistance regularly before your session using a paper towel.
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.
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.
Watertight capacity when closed: 20 liters Height: 17.7" Width: 11.8" Thickness: 7.9" Weight: 1.6 lbs
WATER RESISTANCE TESTS: TEST 1: "PUDDLE OF WATER" The bag is resistant to shallow immersion for 8 hours in 4" of water. This test corresponds to a bag floating in a water-filled boat or to a brief fall into the water. TEST 2: "SHOWER" The bag is resistant to a shower of 450 L/m²/h lasting 4 hours. This test corresponds to heavy rains or splashes from waves.
Rinse with clean water and dry the product before storing for long periods to keep the materials in good condition.
