Not durable enough for the back country use
"Took this out to Isle Royale to use it for the first time. I kept it in an outside side pocket for easy access while on the trail. At one point I set my pack down for a break and it tipped over, when I righted the pack my bottle was leaking and a large hole had been torn near the top. I tried fixing it in the field but nothing would stick: I tried gorilla tape, electrical tape, regular duck tape, and medical tape-nothing worked. Unfortunately it is not durable enough for me to recommend use in the back country unless you have a backup reservoir. Very disappointed that I didn’t even get to use it a full day. Cascade, please either make this plastic more abrasion resistant, or at least give us an option for a way to patch it."
