About this item

• DUAL-LAYER FILTRATION FOR OUTDOOR RAW WATER - Built with 0.1 micron hollow fiber ultrafiltration membrane paired with carbon fiber layers, this squeeze water flask captures sediment and floating particles while reducing unpleasant odor from stream, lake and river water. It processes natural outdoor water via physical filtration for daily outdoor drinking use.
• 0.4MM THICK FOOD-GRADE TPU
• HIGH FLOW PERFORMANCE - Constructed with thickened 0.4mm wear-resistant food-grade TPU, the flask contains no BPA additives. It supports a steady 1.5 L per minute water flow, and each filter cartridge delivers up to 1000 liters (264 gallons) of filtered water capacity. You may skip single-use water treatment tablets for repeated outdoor use.
• ULTRALIGHT COLLAPSIBLE DESIGN FOR OUTDOOR CARRY - Weighs roughly 100g, the flexible soft body fully collapses down to pocket-friendly size. It fits jacket pockets, backpack side compartments and outdoor packs, ideal lightweight gear for hiking, camping and backcountry trips.
• STANDARD 42MM UNIVERSAL THREAD FOR FILTER SWAPS - Equipped with standard 42mm thread opening, it matches all replacement filters with identical 42mm size specs. The wide mouth opening lets you reach inside with simple cleaning tools to wipe inner residues with less effort.
• TOOL-FREE RINSE & CONVENIENT AIR-DRY DESIGN - No extra tools or backwashing steps needed for routine upkeep. Simply fill the bottle with clean water, shake gently and rinse the built-in filter to clear trapped particles. The hanging loop at the bottom lets you hang the flask upside down after cleaning for thorough air drying, which helps maintain consistent filtration performance over time.
• LARGE CAPACITY COLLAPSIBLE DESIGN - Collapsible water filter bottle features a 25.4 oz capacity to store adequate drinking water during lengthy outdoor activities, including hiking, camping and remote backpacking trips.
