The TETON Sports Mountain Adventurer 4000 is a lightweight but highly technical internal frame backpack that is ready for any type of mountain sport. It’s an ideal pack for backpacking or alpine climbs and every adventure in-between. The 66-Liter volume provides ample space for all your alpine equipment including skis, snowboard, or snowshoes. The strong and rugged pack shell is made from a treated 420D Oxford, which can stand up to even the roughest terrain in the most extreme parts of the world. Oversized zipper pulls on the exterior pockets and main compartment zipper are easy to use even with gloved fingers. The Mountain Adventurer 4000 provides superior comfort and a precise fit with the help of tension adjustments at the shoulders, chest, and torso. Aluminum stays provide strength and support right where you need it. The dual waist belt has wishbone construction to sit comfortably on your hips. A thickly padded lumbar area provides exceptional lower back comfort. Other comfort features include thick shoulder pads and air channels along your back to maximize air circulation. The Mountain Adventurer 4000 is also hydration compatible with an integrated Velcro hang tab for easily hanging your hydration bladder. Room enough for a large 3-Liter bladder. Bonus features include: Two mesh pockets, to fit water bottles or other items requiring easy accessibility, multiple side compression straps, and an upper compression strap help keep your backpacking gear cinched tight to reduce pack shift.
