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.

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

Out of the box and onto the trail seamlessly. Filled the bladder, stuffed the pockets and with a few quick tugs on the straps I was off. It rides in a similar way to the Hydraquiver single bottle I already have, nice and high on the back. Filled it didn't bounce or slip. I forgot I was carrying it at many points during the run it was so comfortable. This will get many many miles!

I purchased this Endurance Pack for my first 100 mile run which was the Hennepin 100. The pack worked great, I was able to store all the items I needed to help me accomplish this event, as there are plenty of storage compartments to keep what you need. I was able to keep the fluid to a minimum and top up at the aid stations along the way. The pack is light weight, and you really do not know you have it on especially the later stages of the run where you are getting tired.

Ok so about 7 years ago I got the hydraquiver single barrel and thought it was Amazing!!! I loved having my hands free while running and being able to carry my keys and snacks while I ran. Just recently as my running has picked since having 2 kids I decided to invest in the Endurance Pack (2L bladder) and I have fallen in love all over again. I love all the storage but the best part is how much water I can carry and not feel it bounce around. So far I have used my pack on trail and on road running and I am in love with its comfort and multiple storage pockets. Love Love Love it!!!!!

The first time I used this pack was last year during the SD100 when I helped sweep the course. I borrowed it from a friend. It was very comfortable and I was impressed with the design. So We purchased our first Endurance Pack 4L - V2.0 for my wife who was training for her first 50k. I also used it on my longer trail runs. She loves this pack in white. How it fits, easy access to pockets and the ability to carry everything she needs on long days run.
She is now training for her 2nd 50k and I am starting to train for the San Diego Ultra slam next year so I purchased another one of these packs. We are very happy with them. I coach many Ultra runners and have also recommended this product.
