Sawyer squeeze has always worked perfectly for me. Can be squeezed or gravity hung. Used Katadyn BeFree for a little bit, but it always clogged on me. At least with a sawyer you can backflush. Used same sawyer for entirety of a PCT thru hike with zero issues. Always carry aquamira tabs as back-up.
I’ve been a member lurking for a couple years now. I guess it’s time to actually start engaging. Lifetime Western hunter who’s been getting humiliated by deer and elk since I started hunting in ‘93.
