Summer Freedom

With Covid hitting in March, all the water fountains on my running paths are currently closed. The hydration pack gives me the freedom to go for 2 to 3 hours and still have water available on these hot days on the run or hike while also safely stowing my keys, phone, gu, and anything else I can think of. Amazing shipping speed as well.

Great Pack and great capacity for H20

I went to orange mud because of the capability to have a vest style pack but hold 2L of water, I was surprised when it was actually smaller than a competitors 1.5L vest. Not a lot of room for other storage but this is mainly for holding water and not packing up so I did not mind that. It is also very comfortable, when filled to the max with water you will feel a small bulge in your back but after a few sips that goes away and you barely know that you have the pack on. I have used this for 24 hour mtb/bikepacking rides and never had a regret that I was wearing it!

Great Pack!

Was in the market for a hydration vest due to training for an Ironman Triathlon. Several on my tri team recommended I check out Orange Mud and I am so glad I did. I have used the vest about a half a dozen times already and love it. I wanted a hydration pack that not only held enough hydration and nutrition, but could also carry my phone and not bounce. This pack is all that and more than I could hope for. I bought the Endurance Pack V2.0 and can now carry enough water for a 2 - 3 hour ride plus nutrition. I barely sense the weight, mostly because it fits perfect and doesn’t bounce. With all the pockets, my phone and all my nutrition is easily accessed. This has literally transformed my long runs and I only wished I would have made this investment sooner.

I bought it for the pockets but love it so much more.

I didn't really need a new fluid back pack back (not sure what else to call it without using a brand name) but i wanted one with front pockets. The pockets are great...easily accessed and yet a cinch (literally and figuratively) to secure. Even better was the fit of the pack. Very easy to adjust for comfort but, more importantly, the shoulder straps felt softer than my previous pack and did not chafe my neck. I usually were packs in warm weather when I am sleeveless so the softness was really appreciated.

Perfect Form & Function

Did a lot of research before buying my first OM pack and now own three. Great balance of capacity and form that won’t bounce around while you run or feel like you’re wearing a backpack. The extra zipper pouch in V2.0 is perfect for keys and a cellphone. Highly recommend
