Incredible flow rate and featherlight in my daypack. No weird plastic taste and total peace of mind drinking from mountain creeks. Highly recommend this filter!

Compact, rugged, and essential for bug-out bags. Tested it on murky stream water while camping and it filtered completely crystal clear. The Buy 1 Get 1 Free deal is unbeatable.
