One of those saved my ass on a solo, overnight kayaking trip. I mostly brought beer, ice and food in my tow-behind cooler because I had a Life Straw.

The trip was hell, most difficult thing I’ve ever done, wasn’t sure I’d make it out. Was good on water until the next day when I finally broke out onto the main creek.

Cut the top off a can and sucked down 7 refills of creek water. Tasted exactly like warm, flat, tap water.
