understand that there are a few basic categories. Small, typically fluid only type of packs. Holds fluids and minimal "extras". Mid sized. And larger (multi)day packs.Unsure of how I would like to have two bottles on my chest in the front, I took the plunge on the UD. I must say, after the first 30 minutes, I never even remembered they were there. Sloshing was very minimal. Bounce in the overall pack is non-existent once probably adjusted.I have come to LOVE the two bottles upfront. Its nice having the option of two different fluids. Water+Flat soda. Water+Electrolytes. etc etc.During a recent 50M ultra, the number of UD packs seen are a testament to the quality, durability, usefulness of the brand. The 2.0 versions I believe are improvements over the originals.One primary reason for this pack over others, was that I could keep my hands free. LOTS of upfront storage for gels, bars. phone. etc. The super-stretch material is such that the back holds a surprising amount of stuff. During training runs for an r2r2r, I intentionally loaded up the pack as full as I could. It was over 10lbs. Once on my back, I really (seriously) forget it was one. Weight is supremely distributed. No bounce. I have some very mild rubbing/friction at the side of my neck. Once because I didnt have the chest straps adjusted. Once tightened, rubbing stopped. a second time was when a chain I wear around my neck moved toward my collar bone and rubbed on the packs piping. Again resolved easy enough.Price was very reasonable. This pack will goes with me on family camping trips in which we hike. GONE are the day of Papa having to be carry everyone stuff in pockets of uncomfortable (for hiking) backpacks.This pack was very well received by others in my running club.There are likely better, more well written reviews out there. But this pack was worth every single penny. Awesome. 5 stars without question. I can't even think of what I would want changed on the pack. Extremely well thought out and planned. Look online as Scott Jureks video explanation and you can see how even the materials were planned.Buy with confidence.

into my run. I wear it over an Under Armor dry fit type shirt and even over that thin material I don't notice the weight.It fits well. I purchased a M/L. I am 6'2, 170ish and wear a 40L in a sports coat. I have the M/L tightened all the way, but it is snug enough to not bounce around. You can adjust the cross straps to thighten in the exact areas that fit your chest.It has enough storage for a long or short run. I have an iPhone 6 Plus. I haven't taken this on a super long run that would merit two water bottles, so up until this point I have carries the phone in the other bottle pocket. You can tighten it enough that you don't feel the phone moving. I also carry gels in the side pocket thats on the bottle pocket. That works great. There is a big back pocket for a light jacket or a hydration bladder if you are so inclined as to use one of those, however it does not come with one. Also, in reference to the side hip pockets, they CAN fit an iPhone 6 Plus. It's pretty snug, but it does fit. As I do longer runs with this pack, I will throw my phone in there.It looks cool.CONs:I don't care for the bottles. At first, I couldn't get the water to come out. Then I realized you have to pull up the nipples to release the flow. Then you still have to squeeze the bottle, and the flow is pretty intense. It's hard to feel the water in your mouth. I prefer the Soloman soft flasks instead, so these bottles are just going to get tossed to the side.The side pockets are actually on your back. I didn't realize that when I was researching it. It's not a HUGE deal, but they are hard to get to. When I start to carry my phone there, it will basically stay there until I stop the run or stop to rest. You can get it out while running, but it's hard to put back in. Those pockets are great for sticking IDs, credit cards, or even trash.Overall, I am happy with this purchase. I'll definitely use it for longer trail runs and marathons. I think I'm going to try a belt for shorter runs such as 10ks.

m for stashing a light jacket, food or anything else you can think of to carry. There are several small "compartments" around the pack which can be used for phone, camera, keys, electrolyte tablets, trash, etc. the thing I liked the most was the water bottles (included) bring in front of the shoulders. This made for easy access and takes weight off your back. There are places on the back (stretch ford) to lash down trekking poles and also plenty of room to lash down a jacket or anything else appropriate. The pack is pretty much waterproof; even when sweating, the clothes I had inside the pack stayed completely dry. There is also room for a small hydration bladder (with tube access holes), if you decided to use that instead of or addition to the water bottles.The only thing that kept me from giving 5 stars was that the large pockets on the sides of the pack, which are big enough for a camera or phone, were hard to access by trying to reach behind you when wearing. You pretty much had to take the pack off. If you just used the pockets for storage and not for quick access, while wearing, then it would not be an issue. Despite that, I would totally recommend this pack. I have used GoLite running pavks before and I like this one much better.
