This pack looked great at first. It has lots of internal pockets for organization and a really neat tool roll, as well as a fleece lined pocket for your glasses / phone / whatever. The magnetic hose clip is pretty cool too. I like the stiff back panel, it gives the bag some much needed structure that the previous generation of Camelbak lumbar packs was missing (the Volt and Charge). The side pockets are nice to have but are much too small to fit anything useful other than a Cliff bar. I'm a fan of the Lowrider design, I've been using a Wingnut Hyper (the original lowrider design) for a couple of years now and it helps with back pain on long rides.
My biggest beef with this pack...... its too small. I'm a big dude built like a gorilla and it does not fit. With the straps loosened all the way its still much too tight to get around my 38" waist comfortably. The shoulder straps are up and over my shoulders for the most part and the sternum strap it just below my neck at its lowest setting. I can't ride with this pack. Its like putting on a Hello Kitty backpack for a normal sized person, just does not work. In contrast, my Wingnut has tons of adjustment left in the straps when I wear it, I'm sure someone 7' tall could use it. I really wish Camelbak would offer some larger sizes of bags, as it stands the HAWG and MULE are the only packs from them that I can comfortably use. I'll just have to stick with my Wingnut for now.
I have to give this pack a big 0/5 for me. Useless as it does not fit. Fellow Clydes beware.
