  Compact mais fragile

  J'aime bien ce sac très léger, légèrement translucide mais très fragile. Il ne faut pas pousser les vêtements trop forts dans le sac sinon déchire comme du papier sans crier gare. . .

  Great size for a travel bag

  I have about 30 of these of varying sizes. This one in particular is great for small items in a bag so you can compartmentalize better. Quality and colour are great. I would recommend.

  Dry sack

  This is an excellent sack that keeps the items dry. I've used it in the past and was very pleased with the quality and its super light weght. Highly recommend, especially since they come in different sizes.

  Perfect for intended use

  10/20/25

  Bought this for travelling with a lightweight down Western Mountaineering sleeping bag which fits perfectly. Seals up nice and material seem durable for how light it is. Anything more would be overkill as it will always be going inside another pack. Seems like it would be more water resistant than water proof which is fine as, again, it will always be in a pack, but nice that it provides a little extra security. And I really like the Tarragon color.

  Good bag. Sturdy but light. Will buy more. Colour is nice. I used it as my watch bag for offshore sailing.

  Light weight and perfect for hiking.

  Purchased for use during long hikes in inclement weather. The dry bag seems well made and is light weight. Definitely only for use inside another bag as the material is quite thin and doesn’t seem like it would withstand significant wear.

  bon sac

  06/01/25

  Super léger, étanche, très bonne qualité et robuste. Un seul point négatif, il n'y a rien pour tenir le fond quand on essaie de sortir quelque chose du sac. C'est correct pour des petit items, mais si on compresse un manteau en duvet dedans, ça rend le retrait de la veste très difficile.

  Came recommended

  It's the perfect size to waterproof the contents of my Osprey Katari. Can't recommended by experienced hikers and it does what it's designed for very well.
