I've been using these for years now and they have surpassed every expectation: extremely durable, collapsible, fit even on off- brand filters and come with caps that stay attached while you fill- or drink- if you're like me and unscrew the top rather than use the mouthpiece. They come with carabineers if you're into suspending yours outside your pack. I keep mine inside my pack and i love that you can squeeze the air out so the water don't slosh back and forth- the sloshing is highly annoying for me. These bad boys even hold up to being cleaned with a water bottle brush, though I suggest using a softer one so as to not puncture. I think the price is good especially considering how long they last if you're conscientious about maintenance. I always let mine dry by sitting them upside down in the dish drainer and it's awesome that they stay open so they Will actually dry. The next time I need a new filter I'll go for the twin pack that also comes with the matching filter but for now they fit my Life Straw filter just fine. I love these for me and have also given them as gifts to the hikers on my life. Highly, highly recommended!
