Utilizing a highly breathable and durable mesh, this pack is here for the long haul. The entire structure has a good bit of stretch, but we worked to find the balance of maintaining form while allowing plenty of movement in this design. This pack is excellent for running, hiking, biking, and more. The key to fit is to cinch down the sides first, then adjust the front per your desire. The front harness has a lot of adjustability while being super stretchy too. 
  • Mountain Bike: Extremely stable on your body across the choppy stuff, and we extended the shoulder area a bit to allow freedom of movement. 4 front pockets allow for quick access of your essentials on the fly.
  • Running: Short runs or as long as you want to go. This hydration pack is loaded with features to take you any distance. 
  • Hiking: The conforming fit and quick access pockets paired with a very breathable frame means hiking bliss.  
Fit For Ladies: This pack is designed to be friendly with your curves. With multiple anchor points on each side and stretch elastic for the cross connect, you can configure it to fit your shape. The adjustability in sizing is very broad to cover nearly every size and shape. Video on fit here. 
Fit For Guys: This will fit up to about a 52" chest. When loaded things will change a bit, but we took the front shoulder depth and made it deeper than the Vest Packs (in case you're familiar with that fit). So a tad more girth and more vertical shoulder room. 

Optional Accessories

Great Hydration Pack

I got this for a Spartan Super I was running. It is 8+ miles with obstacles. This pack worked great! I only had to take to off for one obstacle and that was a water obstacle but that was mainly because I didn't want to get my snacks wet and yucky that I had in the pockets on my pack. I have sense worn it for 2 more road races and it is perfect. Not heavy, fits nice and snug. I barely knew it was there! Definitely recommend!

Great for MTB

I got this pack because I didn't want a standard long pack or a fanny pack and water bottles don't hold enough for longer rides. A triathlon friend told me about this one so I figured I'd try it out and after few dozen rides I am thoroughly impressed with how it feels, its construction and durability.

Minimal Fast Pack

I used this pack for DK200 2019. It was great, minimal but just large enough for the essentials. Strap adjustability was great and got it dialed in for a snug, nonbouncing fit.

Lives up to the hype

Finally pulled the trigger after eyeing this for a couple years because I wanted something in between my 1.5-liter and my 3-liter packs, and this fit the bill.

I bought this for long distance gravel cycling events. I received it one day before the Open Range 200k in Pratt, KS, and ignored all the conventional wisdom about not trying out new things on the day of a race. It performed flawlessly.

First off all the hype about not really noticing it is even there is pretty much spot on. I barely noticed it was there, and it was secure and didn't shift around or bounce like my other packs.

The way the bladder inserts (basically you just drop it into the pack) is a vast improvement over other packs. The bite valve on the tube doesn't leak and is easy to use. Has enough cargo space for a few extras -- I keep extra drink mix and a first aid kit in mine. The hook clip for your car keys is a nice touch.

The only minor quibble I have isn't even worth taking off a star -- it's the emergency whistle on the chest strap. The 20-mph Kansas wind is enough to make the whistle blow, which gets a little old. I put a small piece of tape on it, which solved the issue.

Used the Orange Mud pack this weekend at Dirty Kanza 200 and again, it worked flawlessly. On a day when everything else went wrong, my hydration pack was not one of them.

My new go-to pack

I love the ease and comfort of this pack. I have tried other brands but always come back to Orange Mud. It has plenty of storage, fits really comfortably, and doesn’t bounce around when running.
