The Mountain Vault is designed with the needs of the explorer in mind. When traveling to remote destinations, protecting your gear becomes even more important. A lockable zipper combines with a waterproof/sealed body to protect your gear on anything from small trips to the remotest mountain destinations. The exterior features multiple tie down points for secure loading on anything with legs or wheels and customizable carry strap options make transport a breeze. The small 42L bag fits in to most airline carry on dimensions, and the large 122L swallows gear for even the largest expeditions, and the 72L is perfect for mid-sized loads.
