Need a super comfortable, super light, women specific backpack? You have to check out Osprey’s newly updated Ariel series. They come in three different sizes, a 55, 65, and 75 Liter. I think the 65 liter is just the right size–not too big, not too small. This pack is highly customizable, coming in several sizes and with a moldable hip belt that you can have heat molded to fit your body. The pack compresses nicely, so if you need it for a smaller load, you can just cinch it down and still keep a good balance.
