Granite Gear Women's Blaze 60

Heading into the wilderness for days or weeks at a time requires a pack that can comfortably haul all your gear—like the Blaze 60L Backpack from Granite Gear. Equipped with multiple compression straps from the lid to the base, you can pack this bag full with cooking and camping gear, food, and multiple clothing options, and ratchet it down tight to carry close to your back for ultimate comfort on the trail. Once you've made it to camp for the night, the top lid detaches and can be worn as a fanny pack with the hip belt for a secure carry to the summit or to retrieve water. When it's time to move on the next day you can secure the lid to the chest of the pack to make your gear more easily retrievable. And as the miles rack up, your back won't feel it with the perfect fit of the Air-Current frame which adjusts on the back panel and hip.
