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.

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.

FAQ

Will this pack fit over a chest protector or body armor? +

The standard MTB Hydro 12L is designed for regular fit. If you're wearing a chest protector or bulky protective gear, check out the Adventure Fit version with extended straps for extra room across the chest and shoulders.

How do I clean the hydration bladder after muddy rides? +

Rinse the 3L Elite bladder with warm water after each ride, then hang it open to dry completely. The plug-n-play hose detaches in seconds for thorough cleaning or quick swaps between rides.

Does this pack work for gravel racing and bikepacking trips? +

Absolutely. The 12L capacity holds tools, spare tubes, nutrition, and extra layers for long gravel races or multi-day bikepacking adventures without bouncing around on rough terrain.

Can I use this pack for trail running or just mountain biking? +

While it's built specifically for mountain biking and gravel cycling, the zero-bounce NDM harness works great for trail running if you need the extra storage and hydration capacity for longer efforts.

What's the difference between the 12L and smaller MTB Hydro packs? +

The 12L offers more storage for all day rides, stage races, or when you're carrying extra gear like a rain jacket, first aid kit, and tools. Smaller packs like the 3L or 9L work better for quick after-work rides with minimal gear.
