You leave before sunrise and come home after dark so often that you're starting to wonder what your house looks like in the daytime. Maybe someday you'll find out, but until then you've got the Salomon Out Day 20L+4L carrying everything you need to cement the outdoors as your home away from home. Designed for your longest single day pursuits, this pack delivers tons of comfort and easy gear storage. Its main compartment is expandable by 4L to tack on added storage when you need it, and its ergonomic carrying system features padded straps and a design that's tailored specifically for female athletes. Staying hydrated on the trail and in the mountains will be easier than ever before thanks to its dual hydration pockets--a standard reservoir sleeve for a hydration bladder and a stretchy pocket on the shoulder straps that keeps a soft 500ml flask close by at all times. Your gear and layers will be easily accessible thanks to the convenient zippered side entry, while trekking pole and ice axe carries ensure that you can always bring the proper gear for the terrain you're facing.
