The Mountainsmith Approach 40 pack is the quintessential, do-it-all pack. Designed for those with a shorter torso, the convenient, panel load-style and carry-on size make this backpack the perfect travel piece for weekend getaways, while the backcountry features and technical suspension make gear-intensive day hikes and fast overnights a breeze. The innovative Iliac Crest Shelf Cup (ICS) hipbelt technology transfers and locks the pack load onto your hips, as the Delta Wing Compression system pulls the load into the lumbar region and focuses on the Lumbar Control Point pad so you can travel farther and in greater comfort. Side mesh pockets stow your water bottle and other easy-access essentials. The Mountainsmith Approach 40 backpack is finished with an Anvil Airway perspiration control system to keep you cool and dry with every step you take.
