USWE-Outlander XC 4L Lightweight Hydration Backpack

A GRAVEL OR MTB PACK SO FAST YOUR CAN BARELY SEE IT

The OUTLANDER XC Hydration Pack 4L balances mid-range cargo space with featherweight construction at just 430g, using USWE's patented No Dancing Monkey 1.0 harness to lock 4L of storage and a 1.5L Elite bladder against your spine with zero bounce through technical descents and punchy climbs. Ventilated mesh straps pump air across your torso while elastic suspension wraps your chest without crushing your ribs, letting you haul spare tubes, tools, and extra layers on long mountain bike rides and gravel races without feeling the load.

Soft mesh shoulder and chest straps pump air across your torso to keep you from overheating when the sun is beating down and the trail keeps kicking up. At just 430g without the bladder, this lightweight hydration pack disappears on your back until you need to grab a gel or stuff a jacket into the main compartment. The included 1.5L Elite hydration bladder with fixed coupling keeps water flowing without leaks, and the hose routes cleanly over either shoulder so you can sip without taking your eyes off the trail.

Tech & Specs

• NDM 1.0 harness: 4-point elastic suspension locks the pack to your torso for 100% bounce-free riding on rough terrain.
• 4L total volume: Hauls a spare tube, multi-tool, snacks, and an extra layer without turning into a cargo mule.
• 1.5L Elite hydration bladder: Fixed coupling system prevents leaks and delivers smooth water flow on long rides.
• Ventilated mesh straps: Soft mesh across shoulders and chest keeps air moving to prevent sweat buildup.
• 430g pack weight: Featherweight construction keeps the load minimal for fast cross country rides and gravel racing.

Fit & Kit

Dial in the fit by adjusting the elastic chest and shoulder straps until the pack sits high on your back without riding up into your helmet. The stretchy harness should feel snug but not restrictive, giving your lungs room to expand while keeping the pack stable through technical sections. After each ride, rinse the Elite hydration bladder with warm water and hang it to dry with the opening propped open to prevent mold. The pack is compatible with USWE's NDM 1 accessories like the Action Camera Harness, Organizer Pocket, and Chest Pocket for riders who want to customize their setup for bikepacking races or all-day mountain adventures.
