Gregory carefully considered the construction of the Women's Cairn 58 Backpack to maximize comfort, organization, and overall ease of use while you're backpacking. The Response LT suspension system is designed to align to the natural angle of your hips for a more comfortable feel, and when coupled with the Wishbone Wire frame, it distributes the weight to your hips where your body can more easily carry the load. The shoulder straps utilize Gregory's Monobond architecture which is a four layer material bonded together for a low profile fit and feel.Where the Cairn 58 really stands out is with its organizational features, which includes Gregory's Trail Smart Packing System. The system allows the pack to be accessed from the top, front, and sides. This system provides access to different items throughout the day, without having to dig through your tent, sleeping, bag, and rain gear just to get a snack. The main compartment accessed from the top easily stores all camping gear such as a tent, sleeping bag, and clothes. The second trail compartment is designed to hold those items you need throughout the day like your water filter, rain gear, and lunch. The third compartment can be accessed with the pack still on, and is ideal for your maps, camera, and quick snacks. In addition to these separate compartments, the pack features a hydration bladder compatible design that can be accessed without having to open the pack, and a water resistant top lid pocket with roll top closure for dry storage space. The pack is also fitted with an integrated, color matched rain cover, so an unexpected afternoon rain shower doesn't leave you running for cover.
