Comments: Tried it out on a 10 mile run this past weekend.  If I had to use one word to describe it, I would use SWEET! This is  the most comfortable pack I've ever had. Lightweight, no bouncing and it has pockets on the straps for gels or whatever.  Very easy to customize the fit to your shape and size.  I was able to drink on the run without any problem and very little thought.  It was easy to unclip and clip the bite valve back in place. I would definitely give this pack two thumbs up.

Comments: Was apprehensive to buy this because I'm a 5'10" female and was worried my shoulders would be too broad.  Not the case.  Love this thing!  Wore it for a marathon and had no bouncing or chafing.  Hold everything you could possibly need.  Clipping the tubing into place each time you take a sip can be annoying because you physically have to look at it, but this DEFINITELY beats a hydration belt any day.

Comments: I've been looking for an alternative to the waist pack due to needing more water.  I have also used the handheld bottle, but got tired of holding it.  I've used the Nathan waist pack, but the 8oz bottles are just too small.  I thought about getting one that held 4-6 bottles until I thought about having to fill them.  I read all the reviews on several other sites and I'm VERY happy with my purchase.  It's nice because there is no "bouncing" and I have 70oz!!  I live where it is VERY hot and I need a lot of water.  The bladder is really easy to fill.  I fill it first with ice cubes and then add 32oz of water.  When I get done with my run I still have ice cold water to drink!  Also I just discovered I can fit a "Silk Soy" chocolate mild in the pack too :)  I'm really happy I got this pack and I will never use anything else. Plenty of room for iPhone,keys,money and ID.  Get it!!!

Comments: I finally had to have a larger hydration unit than my handheld for 50K training runs. I don't like waistpacks because they're too confining, so I ordered this pack. Took it out last weekend for a 22 mile run in the mountains and it worked great. It didn't bother my skin and had plenty of convenient storage for other items. I'm 5'10" and thin, and the pack was a good fit. No bounce.  It was also easy to clean, fill and no leakage. So happy with the purchase!

Comments: I got this hydration pack when I started going out on long trail runs where the water supply on my belt was not enough. I do not drink very much when running, so I guessed the 70 oz would be just right for trail runs up to 4 or 5 hours, and as it turned out, I was pretty right on that. The vest has an excellent fit, no bouncing or sloshing, it is well ventilated even for hot days, and the straps are adjustable over a wide range. I am rather small chested, and I tried the chest strap in two positions, first above my breasts, where the fit was very good, then below my breasts, where the fit feels even better. Other than some reviewers on the internet, I have never had problems with leaking seals in the bladder. The pouch is 100% leak-proof, and the quick-fill sliding top works very well for me. It takes some wiggling to remove the hose from the bladder for cleaning, but after the first few times this can be done easily. Cleaning of the bladder is easy, thanks to the wide opening on top, and it may be turned inside out for drying, just follow the instructions printed onto the pouch. There is a clip on the front of the vest to secure the hose, which is a nice feature, as there is nothing dangling around. I like the two front pockets, one can be zipped, so it is a good thing for car keys, cellpone or some change, and the other pocket has an adjustable elastic, which is great for water bottles or a rolled-up map. Only drawback is that the zipper pocket is not waterproof, so you better put your cellphone into a ziplock bag on rainy days. The extra pocket on the back is big enough for some snacks and emergency supplies (band aids, tape, etc.), and a rain jacket may be strapped to the pack. The vest is a good size even for small-framed women like me (5'5", 110 lbs), who usually have trouble with larger packs.
