Fit, Specs & Care

How To Set Up The Harness?

All of our NDM 1 products are unisex and are designed and tested for both men and women. To set up the harness follow the steps below.

Put the backpack on. Adjust the horizontal chest straps to a comfortable length (The two "d-rings" allow you to change between a larger and smaller size). Use the outer ring for the large size and loop through both for the smaller size.
Adjust the vertical shoulder straps (If needed) to adjust the height of the buckle, the center buckle should align around the height of your solar plexus. Do note that a few models like Race 2.0 and Outlander PRO does not have this setting due to their low weight.

Hydration Systems

ELITE

Reverse by placing your hand in the bladder, grab the bottom, and pull it back through the top opening, just like turning a sock inside-out. The molded opening can also be flipped after the bladder body has been reversed. Then, throw it in the dishwasher or rinse with mild soap and water. Make sure to let the bladder dry out completely while reversed.

Full Description

Design & Action

Racing cross country or grinding gravel miles when every gram counts and every second matters means you need a hydration pack that vanishes on your back. The Race 2.0 2L XS is a stripped-down MTB hydration pack built for smaller frame riders and competitive athletes who want zero bounce, maximum airflow, and just enough room for essentials without carrying dead weight. USWE's patented No Dancing Monkey harness locks this pack against your torso with a 4-point suspension that flexes with your body while keeping the load completely stable through rock gardens, sprint finishes, and sketchy descents.

At 230g without the bladder, this is one of the lightest hydration packs you'll find that still delivers serious performance. The mesh back panel and shoulder straps create constant airflow to keep you cool when you're redlining on climbs, while the 2L Elite Hydration Bladder with Plug-n-Play coupling gives you fast refills and reliable hydration access. The streamlined design keeps bulk to a minimum so you can move fast and stay focused on the trail ahead.

Tech & Specs

NDM 1.0 PRO Harness: 4-point elastic suspension system that clamps the pack to your back for 100% bounce-free riding on rough terrain
230g Pack Weight: Ultra lightweight construction that disappears on your back during long distance cycling and fast mountain biking
2L Elite Hydration Bladder: Wide opening bladder with Plug-n-Play quick release coupling for easy refills and secure hose connection
Breathable Mesh Back Panel: Ventilated design with mesh shoulder straps for good airflow during hot weather rides and multi-hour races
Minimal Storage: Compact 2L total volume with quick access pockets for carrying phone, keys, and snacks without extra bulk

Fit & Kit

The XS size is designed for smaller torsos and riders who want a snug, race-ready fit. Adjust the elastic shoulder straps and chest buckle to dial in the perfect tension, then cinch the waist strap to lock everything down. The harness should feel tight enough to eliminate movement but still allow unrestricted breathing during hard efforts. To clean the Elite Hydration Bladder, disconnect the tube using the quick coupling, rinse with warm water, and hang it to dry with the opening facing down.

FAQ

How do I adjust the NDM harness for a secure fit? +

Pull the elastic shoulder straps tight first, then snap the chest buckle and adjust it until the pack sits high on your back without restricting your breathing. Finish by cinching the waist strap to lock everything in place.

Can I use this pack for trail running or is it only for mountain biking? +

The Race 2.0 2L XS works for trail running, gravel biking, and cross country mountain biking. The NDM harness keeps it stable for any high-speed activity where bounce is a problem.

How do I refill the hydration bladder without taking the pack off? +

The Elite Hydration Bladder has a wide opening at the top that you can access by reaching over your shoulder. The Plug-n-Play coupling also lets you disconnect the tube for faster refills at aid stations.

Will this pack fit if I'm between sizes or have a larger chest? +

The XS size is designed for smaller torsos and frames. If you're between sizes or have a larger chest, check out the standard Race 2.0 2L for more adjustability and a better fit.

Can I add extra storage pockets to this pack? +

Yes, the Race 2.0 2L XS is compatible with the Phone Pocket NDM 1 and Organizer Pocket NDM 1 that clip directly onto the harness for extra storage without adding bulk.
