LifeStraw Squeeze Water Filter

From the Amazon Listing

• DUAL-STAGE FILTRATION BUILT FOR BACKCOUNTRY DEMANDS — The Bachgold Squeeze runs an electro-adsorptive nanofiber layer alongside a 0.2-micron hollow fiber membrane — lab-tested, field-ready filtration that goes beyond what single-stage systems can do. Engineered to intercept what standard membranes miss. Whether you're on a thru-hike, a bushcraft expedition, or building an emergency kit — this is the portable water filter that earns its place from day one.
• ULTRALIGHT & POCKET-READY — WEIGHS JUST At 80g (500ml) and 95g (1000ml), the Squeeze folds flat when empty and disappears into any pocket, hip belt, or go-bag. Built for backpackers, hikers, and survival-ready adventurers who refuse to carry dead weight. Designed and manufactured in Switzerland — where every gram and every millimeter is deliberate. The backpacking water filter that fits everywhere and lets you down nowhere.
• SQUEEZE-TO-DRINK — NO SETUP, NO WAITING — Fill the flexible TPU pouch from any freshwater source and squeeze directly into your mouth or any bottle. No pumps, no gravity bags, no assembly. The squeeze-activated flow puts you in control of speed and pressure — ideal whether you're filtering fast on a trail or rationing carefully in a camping or emergency situation. Gear that just works when it needs to.
• YOUR COMPACT BACKUP FOR SURVIVAL, TRAVEL & EMERGENCIES — From backcountry camping to international travel to emergency go-bags, the Bachgold Squeeze delivers reliable filtration when access to clean water isn't guaranteed. Lightweight enough to forget it's there — dependable enough to bet on when it matters. Compatible with standard 28mm bottle threads for seamless integration into any outdoor setup
• SWISS-MADE, LONG-LASTING & WORTH EVERY PENNY — Designed and manufactured in Switzerland by a brand trusted by over 50,000 customers worldwide. The electro-adsorptive layer filters up to 500L; the hollow fiber membrane extends to 1,000L — making this one of the best-value camping and hiking water filters on the market. Includes squeeze pouch, filter unit, and lid. No extras needed. Everything you need, nothing you don't.
