The Gregory Women's Maya 16 Pack is a lightweight pack for speedy day adventures. The pack begins with the BioSync suspension, hugging it close to your body so it follows your every move with die-cut foam for comfort and breathability. The 16 liter size Fits just the essentials: water, lunch, and a layer or two. The front pocket can hang onto a bike helmet or stuff a rain shell into it for fast grabbing when the skies open up. All your gear is close at hand, from a drink tube clip to a sunglasses loop at the shoulder straps, to compass and knife at the hipbelt pockets. Get out, enjoy, and make it back to the car so you can meet your friends for an evening BBQ. That's what I'd do anyway.
