Vraiment pratique. Prend peu d’espace une fois vide. Goulot d’une dimension adéquate pour le remplissage, l’utilisation d’un filtre Flux ou d’un stéripen

I love this bottle
Review by David J. on 1 Mar 2025 review stating I love this bottle
This bottle works great for traveling. Easily compactible, holds its shape when you need to, and doesn’t leave a taste to the water.

Great compressible bottle.
Review by Jonathan B. on 5 Jan 2025 review stating Great compressible bottle.
I wanted this bottle as a compressible, lightweight, backup, spare bottle for hiking in the summer. I also wanted something that could fit the Katadyn BeFree water filter as I also wanted a backup to my MSR pump filter which broke on me last summer. This fits the filter perfectly and is very small when compressed. I can stash it in my pack when no...Read MoreRead more about I wanted this bottle as a

Compact and practical
Review by Daniel R. on 26 Dec 2024 review stating Compact and practical
Great build quality, size and design. The cap is a bit hard to pop open but that is a good thing in my opinion. Love the colour and handle. Great for saving on weight and size during camping trips.

Great bottle, great material, very packable
Review by Jesus G. on 18 Oct 2024 review stating Great bottle, great material, very packable
I had to get a new silicone bottle as I lost mine during my last trip. This is a newer version, still like the concept of the bottle i liked better the old wide mouth opening but this works too. I have used several hydroflask bottles before and i am very happy with them. Totally recommend

Ultralight Reuseable Collapsible Bottle
Review by Jocelyn D. on 27 Sep 2024 review stating Ultralight Reuseable Collapsible Bottle
I really like this bottle. It is very light and folds up to be quite compact. It is similar in size to the Nalgene 1 liter bottles. Takes a bit of getting used to the bottle collapsing in when you take a drink. I like the loop, handy for hanging on your pack.

Has a slight smell which has gone away
Review by Brian C. on 8 Sep 2024 review stating Has a slight smell which has gone away
Had a slight smell when I first got it. Thoroughly washed it with some dawn soap and warm water and that seemed to have helped. Exactly what I was looking for, for my travels and ability to put a carabiner on it and attach to backpack
