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.

Sleek and lightweight

I have used the Endurance Pack V2.0 for several gravel bike races and rides over the last year. It outperforms other brands and the quality is outstanding. It's not bulky and very lightweight. The zipper, pouches, and bungees are well thought out. Only change I'd make is for the cinches on the shoulder strap pouches to be "one-handed" (like on the Revelate feed bags) but not that big of a deal to subtract a star. The Endurance Pack V2.0 is perfect for any adventure.

Excellent endurance pack

Fits well and hardly noticeable when running. Holds just the right amount of water plus enough storage for gels/chews, phone, keys and extra water bottle. Cant believe I waited this long to get one!

Snug fit

Plenty of adjustments for a snug fit. Vest doesn’t bounce once you adjust the straps. Secure the sides first and then the front.
