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.

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.
Tech & Specs
NDM 1.2 Harness: Patented 4-point suspension system with elastic straps that flex with your breathing and lock the pack against your spine for zero bounce on rough trails.
9L Total Volume: Hauls tools, snacks, extra clothing, and a bike pump with organized compartments and a quick access tool pocket so you're not digging through chaos mid-ride.
3L Elite Hydration Bladder: Includes plug-n-play coupling for fast refills and a leak-proof design that keeps you hydrated on long distance gravel cycling or technical MTB races.
590g Pack Weight (770g with bladder): Lightweight construction that won't drag you down on climbs but is tough enough to survive crashes and mud.
Breathable Mesh Straps & Back Panel: Keeps airflow moving when you're grinding uphill in the heat, reducing sweat buildup and back fatigue on all-day rides.
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.
FAQ
Can I wear this pack over body armor or a chest protector?+
The standard MTB Hydro 9L is designed for a close fit without extra gear underneath. If you need to wear it over body armor, check out the Adventure Fit version with extended straps built for that purpose.
Will this pack fit if I have a small waist or narrow hips?+
Yes, the elastic NDM 1.2 harness adjusts to fit a wide range of body types, including smaller frames. The straps use Velcro adjustment so you can dial in a snug fit without excess strap flapping around.
How do I clean the hydration bladder after long rides?+
Pop open the wide slider opening at the top, rinse it thoroughly with warm water, and hang it upside down to dry completely. The plug-n-play coupling disconnects easily for cleaning the tube separately.
Is there enough room for a bike pump and a rain jacket?+
Absolutely. The 9L volume includes multiple zippered compartments and a dedicated tool pocket that easily fits a mini pump, multi-tool, spare tube, and a packable jacket with room left for snacks and a first aid kit.
Does the pack stay put on really rough, technical trails?+
That's exactly what it's built for. The No Dancing Monkey harness system locks the pack to your back with zero bounce, even when you're hitting jumps, drops, or hammering through rock gardens at speed.
Customers love how the No Dancing Monkey harness system keeps this pack locked to their back with zero bounce, even when loaded with 8lbs of gear. Riders consistently mention the superior stability compared to traditional harness systems, with many calling it the best hydration pack for enduro riding. The 9L capacity gets praise for fitting tools, jackets, and first aid kits without feeling bulky, and the quality construction and solid feel make it a pack that riders trust enough to buy again.

Customer Reviews
Overall rating: 4.7 / 5 from 46 reviews.
My wife loves wearing this backpack. She wears it everywhere, even when she's not cycling.💜💜💜
Overall it's the best hydration pack I've ever used. The only issue stopping me from giving it 5 stars is the opening for the pocket that the bladder fits into is very difficult to insert a full bladder through. I have resorted to just not using it and sliding the bladder in without it, which seems to work well.
This is my second one, retired my last one after 5 years of hard service many trips and at least three times use a week. The new one is a slightly different size. Great quality, looking forward to another five years of great use.
I absolutely LOVE this pack! I'm 5'0" 120lbs, so pretty small frame, the pack fits my perfectly, doesn't go too far down my back or around my sides. Very streamlined. Carries 3L of water weight very comfortably, with just enough room for other warm weather essentials (sunscreen, snacks, one layer, pack towel) Absolutely my go-to summer adventure bag! Just what you need in a super sleek package
Smidig, har vatten och verktyg samlat på ryggen händer fria då jag servar min son som kör motocross.
använder även en cammelbag när jag åker enduro :-).
Ha en fin sommar!
Love the size and fit of my Hydro MTB 9. I have thrown about 8lbs in it and it is still quite stable on my back. The harness is far more comfortable and stable than a traditional harness system like on my Osprey Raptor 8.
The pack is awesome and I will never use a different brand. USWE for life. However.... Processing and shipping was absolutely HORRIBLE. it took almost three weeks to even ship out, the customer service lady just fed me lies and BS.... and they sent the wrong color. The packs are the best available for what I need. They are superior to the competition. When it's time to order a new one..... I'm NOT ordering straight from USWE again, I'll buy it from a retailer.
I wasn't even going to review my experience but they sent me email wanting me to do so..... so here it is.
I got this for my wife as a present. It is very well made and is large enough for people who want to bring a light jacket, tools, and a first aid kit. I tried it on and it does not move on your body, it is pretty cool.
When I test the "No dancing monkey " system for the first time, I think that's the hydration backpack for an enduro rider. And this is my second Uswe backpack.
Love it!
I bought it on sale, two weeks later I received a bill from Fed Ex for 38.00 for a tariff charge! The problem I have it was not mentioned! If I knew I wouldn’t have bought it or at least it would have my decision! Not happy customer!!!
I purchased this pack for a little more storage. Previously I had the 3L version which I loved but wanted just a bit more space and a slightly larger bladder for backcountry rides. This 9L bag checks all of the boxes. Super comfortable pack, 3L bladder, room for extra parts and tools, extra clothing layer and snacks. The buckle system is still amazing. Plus it absolutely drips steez. Looks so good
Title says it all. Best MTB day pack I've ever used. I prefer to ride without a pack, whenever possible. But, on longer days, sometimes it's required, and when it is, I really do enjoy using this pack.
Love the light weight durable fabric.
Just enough room for the basics.
I�m female and find the straps cut my breasts rather than sit under them. Once you add water the pak does not sit as the website states.
I tried loosening things , tightening things and finally crisscrossing the straps. The crisscross helps. However this oak is probably great for guys. There must be a better answer for women
Like the materials and concept but would not purchase again
If you are a guy, mine is for sale
Great pack. Switched over to these when my old traditional packs would bounce when riding. This style eliminates the bounce. Super tough, had an older smaller version that held up great after few hard crashes. Got this style for more room for gear and tools. Straps have Velcro adjustment so fits well. My wife tried and did not like it, so if you�re female and have larger breast, try one on first. Overall love these packs.
The bladder is very tall and skinny.
It is a little more difficult to stuff in the WAY to skinny pocket than other hydration packs including a USWE Airborne.
It's a little thing but after sealing the bladder, using right hand to slide the clip on, the quick disconnect is on opposite side. It is not that big a deal to turn over but if you are resting the pack on something the quick disconnect is scooping up dirt while sealing the top.
This is the best hydro pack for bike riding! The no dancing monkey design really helps the feel for the ride instead of having a pack sliding around your back feeling uncomfortable. I highly recommend!
