Review on 💧 Hydrapak Flux - Collapsible Backpacking Water Bottle: Compact, BPA Free and Spill-Proof Twist Cap for Outdoor Adventures (1 or 1.5 Liter) by Vince Preston

I've had it for about 3 months and used it daily like a regular bottle. I've kept it in the car, used it for training and never used its ability to shrink when empty. Well there is this ring at the top around the mouthpiece that forms a seam with the rest of the bottle and after a few months of use these little pinhole like cracks started to develop. Now it is useless and constantly leaks. I don't recall piercing it or doing anything to evoke it. I think the integrity just went down. I would not recommend it for this reason. If they can make it more durable it would be great to pair it with the same brand 1.5L bladder that I use in my backpack.
