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!

Comfortable and practical

I wore my new vest on a 14 mile run yesterday and found it to be very comfortable and I like where all the pockets are. Glad I got it!

Love all the pockets

I finally have a place to put my glasses, nutrition, and tissues without having to dig for them. So easy to get out and then put away while running.

Works excellent!

Love the way it sits high and fits snugly with no movement. Have run several miles with no rubbing or chafing. Love it!

Comfortable and durable running vest

My previous Orange Mud vest is still viable but it was time to upgrade. V2.0 provides what I like about V1 in that it is comfortable yet durable, pliable, but adds additional pocket space. It still has a minimal footprint which is great. I can hardly tell I'm wearing it even when I'm carrying water.
