Have been looking for a weekend backpack for city traveling/skiing, with a possibility of using it for mild hikes in the future. So something that's relatively light and breathable enough for hot days, but which is not too whimpy and can withstand cold days in the Northeast. I'm 5'5'' and have narrow hips, and the small frame and hip-belt fit me perfectly. The shoulder straps are amazingly comfortable and seem very durable and for sure a woman was a part of the team who designed it. There are no pressure points, no large pads that rub against your armpits, and it's so adjustable that I can wear it with a tshirt on or over a winter jacket without a worry of it fitting oddly.
BOTTOM Line: most comfortable one I've tried on, and the perfect size (I got 26L) for weekend/few day excursions.
