HEATHER W.wrote a review of Mountain Hardwear Wandra 24 Backpack - 1450cu in - Women's on January 20, 2013
Familiarity: I've used it several times
I spent several months trying out an Osprey Sirrus 24 before finally giving up on the organizational layout.
Organization: The Wandra is definitely an improvement, with easily accessible (with the pack on) side mesh pockets that aren't inhibited by load balancing straps. It also has that back stash pocket that I love to stuff things in without opening up the pack. There are two other external pockets that are a bit on the small side, but adequate, an internal mesh pocket, and there is extra space in the pocket that holds the included raincover. Two small pockets on the waistbelt are big enough for my P&S camera, but barely. The outlets from the hydration sleeve pocket are nicely sized to get the tube (with a stopper) through easily. I also like the trekking pole carry straps better than the Sirrus' setup.
Comfort: The reason I kept the Sirrus so long was how comfortable it was. The Wandra is nearly as good, with a semi-rigid frame that keeps the pack off your back for heat management. Women-specific design means it fits my 5 foot, 113 lb frame just fine.
The only thing I don't like is cosmetic - the white straps. Why would you make anything on a pack white? They are sure to get filthy.
I plan to use it on our upcoming trip to New Zealand, and better organization means more versatility.
