I purchased this pack for my girlfriend for short day hikes, and bike rides. This is her first Camelbak so she has nothing to compare it to. However, she is in love. She states, and I quote "This thing is so comfortable in all of the right places. She wears it with a tank, and has no complaints of chafing with the fleece lined shoulder straps. She can stuff it with all of her necessities, and it came in pink! So, now I have to compete for her love...awesome.
