Think again. The Deva 70 uses Gregory's updated Response AFS suspension that delivers a custom fit and automatically registers your hip angle as you move out on the trail. Pack everything you want (and even some things you probably don't need) - you'll be so comfortable on the way to camp, we bet you get there faster and will love those extra comforts you packed to pass the time. Amazon.com As the top-selling women's pack in its category, the redesigned Gregory Deva 70 women's technical pack is sure to please. The pack is outfitted with Gregory's Response AFS suspension system, an independent rotating waist-belt system that automatically registers and adjusts to your hip angle. This pivoting belt mirrors your body's movements and evenly distributes the weight, helping the pack support larger loads without restricting your movement or stressing your hips and shoulders. Gregory also addressed every individual's fit and comfort needs from the beginning with its women's-specific fit. Designed for and tested by women, the Deva 70 is built to fit the female body shape, with narrower back panels than men's packs and a female-specific harness design and cut. Gregory added a variety of extra pockets in addition to the main compartment, including a large front pocket, two side pockets, dual waist belt pockets, and a hideaway water bottle holder. Hydration is always a must while on the trail, which is why the Deva 70 also comes with a reservoir sleeve and dual drink-tube exit ports (reservoir sold separately). Other features include an auto-fit waist belt system, an aero-mesh moisture-wicking back panel, a Gription mesh lumbar pad, a single aluminum stay, water-resistant zippers, and a dual-layer wear-resistant bottom panel. The Deva 70's women's-specific fit is designed to fit a woman's unique body shape.

Shortly afterward, he met Andy Drollinger, the founder of San Diego California Adventure 16. Andy was so impressed with Wayne's design that he invited the Boy Scout to visit the Adventure 16 factory, where he began tinkering with a variety of backpack ideas. Wayne soon became the young company's second employee. Wayne opened his first company, Sunbird, in 1970, but dissolved it a few years later after expressing frustration with the limitations of external frame designs. He founded Gregory Mountain Products in 1977, eventually pioneering many firsts, including being the first to build backpacks in different frame, harness, and waist belt sizes; the first (and still only) pack manufacturer to develop a waist belt system that adjusts to fit different hip angles; and developing the center-locking bar tack, a stitch that ends and locks off on the center of a seam instead of the side for increased strength at major stress points. Gregory is located in Sacramento, California.
