⚡ At a Glance
- • Hydration Flow: High-flow bite valve auto-seals after each sip to prevent drips
- • Best for: Runners and hikers who need lightweight, packable hydration
- • Not ideal for: Users who prefer rigid bottles or require a single, high-capacity container
Pack contains two 500ml collapsible soft flasks with a shrink-as-you-drink design. High-flow bite valve auto-seals after each sip to reduce drips and bounce.
Carry less weight, run farther – with ultra-light 35g collapsible construction
Each soft flask weighs around 35 grams and flattens as liquid is consumed, reducing bulk and movement. Collapsible walls fold down to tuck into pockets or vests.
Noticeably lighter load on long runs and hikes, helping sustain pace and reduce shoulder strain. Empty flasks pack away without taking up space.
Reliable, no-drip sipping – with a high-flow auto-seal bite valve
Bite valve permits strong flow when bitten and closes automatically after each sip to stop leaking. Valve design keeps seal integrity during repetitive use.
Quick, clean drinks while moving, so hands stay drier and clothing stays protected. Dependable performance for both short intervals and long-distance sessions.
Safe, reusable construction – with BPA and PVC-free food-grade TPU
Food-grade TPU material excludes BPA and PVC and resists repeated flexing and folding without breaking down. The material suits repeated outdoor use while remaining lightweight.
Safe for regular drinking and kinder to the environment than single-use bottles. Durable build supports frequent training and repeated refills.
