Comments: Bought this in xs/s, I am 5'8" and 130lb. This thing fits like a glove I love it. Zero bouncing or chaffing. Coming from running with a very, very minimalistic camelbak, the pockets on this are ridiculous. Perfect to stash sammies and waffles for my long runs. The hydration pack lends clean tasting water and is amazingly easy to refill. The only trick I've encountered is the (insulated) tube...it's sooo long. Left on the right side, it's wagging around, so I cross it and attached it to the elastic hook on my left, which makes it positioned for sips. Perhaps this was the design? It doesn't come with directions so I am trying to figure out the logic to some of the bells and whistles (did I mention my previous pack held water, and nothing else?) This pack makes me feel even better prepared for long solo miles on the trail. It does have an emergency blanket and little whistle. Thoughtful extras that I hope I never need. I am pretty satisfied with the cost now that I know the major difference in product quality. This is so worth it.

Comments: Amazing hydration pack! Amazing features, incredible design and construction.
Con: Even the (M/L)isn't made for larger body frames. at 6"1 and 200-210 Lbs., pack is definitely made for smaller runners. Such a shame.

Comments: so it's certainly more expensive than a camleback or other hydration system but this is like no other. it hugs your body and does not move. i had tried belt system with 4 little bottles and that kept moving from my hips to my waist and after 1 hr, i had chaffing marks on my hips. no thank you. this is the way to go. this pack is amazing - plenty of storage, keeps water cold, fits like a glove. looking
forward to many hours of running on the trails with this pack

Comments: Love it, but had issues with the "2 link system" but like the other reviews said, it fits really well, excellent design.

Comments: Wow! What a great pack! I run trail and road (sometimes long, sometimes short), but when I want to spend a few hours
without stopping, this is my choice. Fits very well, and does not bounce (I think that's a first!). Each component was well calculated in this hydration pack

Comments: I did not purchase this pack from Running Warehouse (was not available from them at the time). If you are serious about trail running and want an awesome pack that will not chafe, is light and comfortable, holds all the essentials, has the best hydration system I have ever used which is insulated and bacteria free, then this pack is worth every penny. I have ran at least 150+ miles already wearing this pack and am more and more impressed with it every time. 6'1" 175lbs, I have the MD/LG which fits me well.
