MTB Hydro 9L Hydration Pack

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.

1. 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.
2. 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. 

Design & Action

When you're tackling long gravel grinds or pushing through multi-hour MTB epics, you need a hydration pack that hauls more than just water without turning into a flopping mess on your back. The MTB Hydro 9L Hydration Pack is a full suspension hydration backpack built for riders who want serious storage and absolute stability on technical terrain. USWE's patented No Dancing Monkey 1.2 harness wraps your torso with elastic straps and a precision NDM buckle, locking this pack to your body so it moves with you instead of bouncing around when you're hammering rough singletrack or sprinting out of switchbacks. The 9L total volume gives you room for tools, snacks, extra layers, and a full 3L Elite hydration bladder without feeling like you're hauling a suitcase.

This is a mountain bike hydration pack designed for breathable comfort and quick access to your gear. The mesh ventilation back panel keeps air flowing when you're climbing in hot weather, while multiple zippered compartments and a dedicated tool pocket let you organize everything from your pump to your first aid kit. The sleek black design with reflective details keeps you visible without looking like you raided a corporate catalog, and the adjustable harness system fits a wide range of body types from petite riders to tall athletes. Strap it on for bike adventure races, bikepacking day trips, or any ride where you need to carry more than the basics.

Fit & Kit

Dial in the fit by adjusting the elastic NDM straps around your chest and waist until the pack sits high on your back without shifting. The harness stretches with your movement but stays locked in place, so you can breathe freely without the pack riding up or smacking your helmet. To clean the Elite hydration bladder, pop open the wide slider opening, rinse it out, and hang it to dry. The plug-n-play coupling disconnects in seconds for quick refills at trailside water sources. Compatible with USWE's Phone Pocket NDM-1, Action Camera Harness NDM-1, Organizer Pocket NDM 1, and Chest Pocket NDM-1 accessories for riders who want to customize their setup for bike gear organization or carrying camera equipment.
