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.
