Comments about Granite Gear Granite Gear Serrano 25 Daypack:
Compact but with room for 10 essentials, rain gear, and food for a day hike. Carried a pair of bottles and a filter on a 9 hr. hike over the continental divide where water was accessible and a 3 liter bladder wouldn't have been enough, to say nothing of being a lot of weight to carry on a 3000 ft ascent. The waist belt is formed and functional for distributing load.
