Stow™ 1L

Filled it for a day hike and was surprised how sturdy it feels when full, yet once I drained it the whole thing compressed down to fit inside my jacket pocket. The rolling up trick is genuinely handy for a smaller pack where every inch counts.

Rolled it up and shoved it into my hip pack's side pocket after a long run—that's the whole reason I bought it, and it fits like a dream. The 1L capacity is plenty for a few hours out, and the squeeze filter compatibility is a nice bonus for future trips.

Took this on a day hike and barely noticed the weight since it flattens down to nothing once it's empty. Rolling it up to tuck into a side pouch freed up so much room compared to my old rigid bottle.
