I surprised my wife with this pack. She ran the Disneyland Half-Marathon in August. I read a lot of reviews beforehand wondering what I should get her. Lot's of women seemed to favor the waist packs, but my wife had told me she'd rather have a backpack type. There weren't many reviews of this one, but they were all favorable. She LOVED it the moment she put it on. Says she can barely feel it on her back because the straps are so comfy. There seem to be just the right amount of pockets and the right pocket sizes too. Can easily fit keys, cell phone, energy bars and/or gels, pepper spray, etc... all at the same time. A must have for full and half marathons!!

I purchased this for my girlfriend to use, because she hates running with water bottles in her hands, and it is the most well thought out piece of gear either of us owns. The adjustments at the sides are easy to make, and keep that pack very secure against the back. The front strap slides vertically so as to get you the best fit possible, regardless of endowment. I should mention that this pack talks about being a women-specific pack throughout all the tags that come with it, although that isn't mentioned on the site.
