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!

Love love love it!

This pack is great!! i wear it on all my runs and races now. It is great for carrying fuel and hydration and keep my hands free. The zipper pouch is also great for carrying my wallet when I'm running out a long distance and might need to stop.

I haven't tried it out for a hike yet but I'm excited to do so.

Great fit

This is the first running pack I’ve ever owned. I am blessed with a bigger frame on the top and always had a hard time finding a pack that fit. This pack is awesome! Just one recommendation is some kinda of velcro or device that allows you to tie up the excess straps.

Love this pack

I've tried many packs now and couldn't quite get the right fit. Tried this one and absolutely love it. No bounce, easy to adjust, good storage, and cool color. Can't wait to use for all my long runs.
