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

Very well designed. Compact and snug fit is the key. It has space for just about everything a runner needs including the green pocket. Love the features for trekking poles and the overall comfort. Thanks for everything you do!

The comfort with a fully loaded bag pack is simply amazing. All the mandatory gear needed for the race fits in well so the space management is apt. Also love the vibrant colours. The fact that it can be easily hand washed and dried within a day makes things super cool and so the maintenance is doable. The fabric used is very breathable and perfect!

I bought this for my trail running significant other and he was thrilled with it. I know nothing about trail running gear but it was highly recommended by his buddies and well received by him.

Love my OrangeMud!! Wanna toss my other more expensive packs

I got the 1 liter first for short runs since I prefer a pack and couldn’t find another one that small. Then I started having rib problems wearing my other packs over 15 miles or they didn’t have enough storage. Got the 2 liter bladder Orange Mud - problem solved!!! I never use my other packs anymore. It rides high on the back, fits well, holds a lot and easy to grab stuff. Pole holders came in super handy for my last 40 miler too!! Only complaint is a very full bladder is hard to get in the pack - otherwise it’s perfect!!

Used for a Spartan Beast

I'm not knowledgeable on the subject but I can say that it was exactly what i hoped for. Snug fit. High on my back. Barely felt it. Drinking from it was smooth. Accessing compartments was easy. Would purchase again.

Running and a little biking with it

Haven't done any races with it but so far with the few runs that I have done it's done what I want. It fits real nice to where I don't feel any movement from the bladder, everything is easy to get to wilhile running as well.
