The sweet spot can be a hard place to find, but Gregory nailed it with the Amber 60 Women's Backpack. As the middle child of the Amber family, the 60 is perfect for three- or four-day treks, winter overnights, or hostel trips, with over 3600 cubic inches of space and the ability to comfortably carry up to 45 pounds. The comfortable weight bearing capability is courtesy of the TrailFlex wishbone suspension, which uses a lightweight internal spring steel frame to distribute weight evenly and a padded TrailFit adjustable hip belt to take some of the pressure off your back and shoulders. This lets you load the Amber up without sacrificing mobility, so you can tackle tough trails and technical terrain without feeling like you're about to topple over backwards. Comfort isn't any good without all the necessary features, and Gregory has managed to squeeze them all in without making things overly complicated or confusing. The lid has three secure pockets to hold important items and is removable if you're looking to lighten your load. There's a detachable SideTrack daypack as well, which doubles as a hanging reservoir sleeve when it's inside the Amber. Front, side, and hip pockets hold layers, snacks, maps, and phones, and the stowable rain cover ensures the whole shebang will stay dry if you get caught in a shower. Stash your trekking poles or ice axes using the carrying system, strap extra gear on via the side and bottom compression straps, and even attach portable solar panels to the back using the daisy chain loops, so you can keep your camera and phone charged up as you go.
