Endurance Pack 4L - V2.0 (2L bladder, 4L cargo): Ideal for running and biking

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!

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.

Storage, storage, storage!

I got this pack because I ran out of water several times during long training runs with my smaller packs. Not only does this one hold 2L of water, it also has TONS of storage. I can carry all my "stuff." Food and snacks, extra gear if I need it, phone, etc. So much room!

Endurance pack

Recently used the endurance pack for a 240 mile bike ride across Minnesota. It performed flawlessly. I love how high it sits on my back and allows me to still access Jersey pockets. Not to mention giving me more breathability.

Awesome Vest - Wonderful Company

I've been using the the Nathan Vaporairess for about a year, and it's nice but I always feel trapped in it to get everything secure. I read some solid review both on the OM side and on some FB running groups. I decided to try the Endurance Pack 4L v2.0 and am really really pleased. First, OM shipped my vest, sleeves and patches the day after I ordered them. Super prompt! Second, they were friendly and cool in any exchanges I've had with them - they are so legit and it's reassuring to connect with real people. Third - the vest is extremely comfortable. I got the white vest - no trekking pole ad on. The chest straps are adjustable! you can slide the base of the strap up or down on your chest - i didnt even realize it when I bought it. I really like the adjustable sides straps - that does make a big difference. I am 5'2" and 135lbs and it adusts easily. I tuck the side straps in. Have worn for a 9 and 12 mile run to test out and very comfortable. The front pockets have a lot of room - i have an iPhone XR in a good case, and it fits in the front drawstring pocket easily.

Great product!

Excellent

I just bought this, AMAZING!!! I tried other packs and hated them. I don't like to run with anything on me. This is super comfortable. It was 87 degrees out and it did not make me feel warmer. I highly recommend it. Also the fits is perfectly. It took me a little time to get the fit just right.

My favorite pack yet

The first thing I loved about this pack, before I even put it on, is the color, a rich earthy golden brown. Second thing is the fit, which is much more stable, dialed in, and chafe- and bounce-free than any of the other hydration packs I’ve used. Third: awesome storage! With a full 2-liter bladder and 2 flasks, I can have a 6-hour adventure without worrying about running out of water.

Overall, solid construction and a great product
