About This DUAL-STAGE FILTRATION ENGINEERED FOR SERIOUS BACKCOUNTRY USE — The Bachgold Squeeze combines an electro-adsorptive nanofiber layer with a 0.2-micron hollow fiber membrane — delivering lab-tested, dual-stage filtration in a field-ready design. The electro-adsorptive layer is engineered to intercept what standard membranes miss, while the hollow fiber membrane handles the rest. Built for thru-hikers, bushcraft adventurers, and emergency kits alike. ULTRALIGHT & POCKET-READY — WEIGHS JUST 83g — At 83g (500ml) and 95g (1000ml), the Squeeze folds flat when empty and fits in the palm of your hand.

Designed and manufactured in Switzerland for the minimalist adventurer who refuses to compromise on filtration performance. SQUEEZE-TO-DRINK — SIMPLE, FAST, FIELD-READY — No pumps. No gravity setup.
