Benefits and Design Features

Stable lumbar fit: The wide, low-profile reservoir distributes weight across the hips to help reduce sloshing and upper-back load in hip and waist packs.
Fast refills on the go: The Slide-Seal top opens fully for filling with water or ice, then closes with a straight slide for a tight, reliable seal.
Easy maintenance: The reversible bladder body allows users to turn the reservoir inside out for thorough cleaning and drying between rides.
High-flow hydration: The angled Blaster bite valve delivers a smooth, generous flow rate and seals itself after each sip to minimize drips.
Tool-free tube removal: The Plug-n-Play coupling lets the tube stay routed in the pack when the bladder is removed for refilling or cleaning.
Robust construction: TPU film and RF-welded seams are engineered to resist abrasion, flexing and pressure changes in off-road conditions.
Versatile temperature range: Suitable for hot liquids up to 60 °C / 140 °F or frozen contents, supporting both summer and winter use.
