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 Omar Card

I bought this to replace the flexible thin bag that comes with the Katadyn BeFree Filter. I hated crushing this bag with both hands when it was less than half full. It also didn't work in the bottle pocket on the side of the backpack. That works great. It's thicker and seems more durable. Time will tell if the durability will stand up to hiking and hiking. I will update this review if there are any holes or stitching holes. The elastic at the top feels sturdy enough to hang a filled bottle. I bought the 1L because I was worried that the 1.5L would be too flexible to put in a backpack's side pocket or that it wouldn't stand up on its own when full, but this 1L is quite long lasting so i would like to so i went to 1.5l. Maybe I'll get the bigger one after trying it out a bit. I've included a picture of a 1 liter bottle next to a standard blender bottle shaker for reference.
