A highly breathable and durable mesh yields maximum heat release in a tough package. The pack is stretchy, but has a balance of maintaining form while allowing plenty of movement. This pack is excellent for carrying your fluids while running and riding. The front harness is stretchy 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.

Solid pack

Only have used it once for hiking so far and it my first time having a pack. Comfortable on shoulders but still working on adjusting the fit. The only thing I wish was for the pocket with the key clip to be waterproof for when it rains (which is a lot where I’m at). Interested in trying it without a jacket as my arms get rubbed easily.

Endurance Pack 2.0

I love my Endurance Pack V2.0! I was concerned about running with a pack but knew I needed it for longer OCR courses. I am happy with my choice. The pack is light weight holds all my gear and feels secure to my back.

Great trail running pack

I love this pack for my trail runs. The fit is great and it helps me stay in a better posture. Everything I need for a training run has a place. It’s also very comfortable. I’m glad I bought it and plan to purchase a larger OM pack for my longer adventures.

Right out of box wore it for my virtual Boston marathon

Love the low profile along my back and how much it could hold besides 32 oz of water!
