Product feature
  1. Precautions for electronic devices
    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 (5L or 10L) inside a large duffel bag (20L, 30L, 40, 60L). Ensure your bags are closed and check water resistance regularly before your session using a paper towel.
  2. 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 look inflated once closed: this makes it more watertight and allows it to float if dropped in the water.
  3. 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.

  • ITIWIT 20L watertight backpack

    Steve (United Kingdom)
    Used for 2 to 8 weeks
    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

    Albert (United Kingdom)
    Used for 2 to 8 weeks
    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

    Felix (United Kingdom)
    Used for 2 to 8 weeks
    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.
  • Reasonably priced waterproof bag

    Used for 2 to 8 weeks
    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.
