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!

Better quality than expected

This hydration pack is exactly what I’ve been looking for. The fit is extremely comfortable with many options to adjust to your liking. The space is amazing also for both fluids and snacks along the way, as well as my phone in the front pocket so it’s readily available for quick access! Definitely recommend and I’ve received many compliments on the camel color I chose.

Endurance Pack V2.0 Review

I've done a 9 mi run and a 16 mi run in the Endurance Pack V2.0. The pack materials are high quality. There is plenty of adjustment for a real locked-in feel. The 16 mi run was at about an 8 min/mi pace and I experienced no bounce or sloshing from the hydration pack. The green color is great for those who want high visibility.

Love my new pack

I'll be using this pack for endurance riding. I tested it out on a conditioning ride and it feels great. No bouncing or movement, even at a trot. Lots of space to carry snacks and a few trail essentials.
