Probably best known for their full size mountaineering and backpacking technical backpacks, Gregory has recently made a push to address what they call the active trail category. The women's specific Maya 18 and Maya 22 are panel loading day packs that offer just enough room to carry the gear you need for a day spent mountain biking, multi-pitch climbing, trail running, or hiking. I was sent one of the Maya 18 to test and have been using it for just about every activity on my Dolomites trip.
