Stability, breathability, and quick access pockets on the Endurance Pack make it perfect for any endurance event. It features a highly breathable and durable mesh that transfers heat quickly away from your body, yet is still soft on your skin. We balance the use of stretchy materials where needed, but use firm materials where we need to maintain stability of fluids and gear. This pack is excellent for carrying your fluids, plus sized phone, electrolytes, and essentials while running and riding!

Note there are two versions, with the "Trekking Pole Upgrade" and the standard. The Trekking Pole Upgrade version has the hardware to "hold" trekking poles, but poles are not included with this purchase. 

The key to fit, cinch the sides first, not the front, until you feel the pack anchor on your shoulders. Then adjust the front harness as needed so you can breathe during movement.

  • 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: This pack is designed to be friendly with your curves. Just slide the sliders up and down to find the optimal fit and adjust the sides snug. Max chest size is around a 52” chest. If you need bigger let us know and we will add more to them!

Hydration 2.0 pack

The pack works well but could use some cushioning in the shoulder area and also the chest straps this would help especially on longer runs and hikes when the bladder is full

Nice packs

My son and I have been using a couple different Orange Mud packs. I have the Endurance 2.0 and my son uses the phone flask vest. Both are very comfortable and serve their purpose very well!

good low profile pack

I was using the Camelbak Chase Vest for the past couple of years, and really liked it. But I wanted more water for longer rides. I was checking out the larger Chase Pack, and ran across this one. So this pack hold more water and more gear. But it feels like the smaller Chase pack I have. Which is cool
