Key benefits Safe, tasteless water: Made from PEVA that meets foodcontact standards to keep drinking water pure and odor during outdoor use. Worry hydration: Militarygrade doubleseal construction, selflocking joints, a largeflow bite valve with shutoff switch, and a protective dust cover minimize leaks and contamination so your gear stays dry. Reliable in extreme conditions: Built to perform from 4°F to 124°F (20°C to 50°C), with abrasion, tortuosity, and tear resistance for longterm durability. Main features Foodgrade PEVA material — tasteless and compliant with food contact standards for safe drinking water. Advanced leakproof system — double sealing technology with selflocking joints; every reservoir is airpressure tested to ensure leak resistance. Largeflow bite valve with switch and dust cover — easy drinking flow with an on/off switch and a dust cover to protect the valve from dirt. Temperatureresistant construction — maintains performance between 4°F and 124°F (20°C to 50°C) for hot and cold conditions. Widemouth opening — easy to fill (accepts ice cubes) and clean; compatible with standard cleaning kits to prevent buildup and extend service life. Durable build — designed for abrasion resistance, tortuosity resistance, and tear resistance to withstand repeated outdoor use. How this solves common problems Keeps water tasting clean and safe without aftertastes or plastic odors. Prevents accidental leaks that can ruin gear, clothing, or electronics. Performs reliably across temperature extremes so you can use it yearround. Easier filling and cleaning reduce hygiene issues and prolong usable life. Use scenarios Day hikes and hotweather trails: Add ice cubes through the widemouth opening for cold, refreshing hydration on long summer hikes. Cycling and commuting: The largeflow bite valve with shutoff switch and dust cover provides quick sips on the move while protecting the valve from road grime. Coldweather expeditions and winter sports: The reservoir's 20°C to 50°C rating and rugged material resist damage from freezing temperatures and rough use. Care and compatibility notes Clean regularly with a standard hydration cleaning kit to prevent buildup and maintain hygiene. Use the wide opening to rinse thoroughly and to add ice if needed. The valve includes a shutoff switch and dust cover for storage and transport to reduce leakage and contamination.
