The OutThere MS-1 Backpack

The MS-1 pack has been replaced with our New MS-2 models. If you would like an MS-1, please contact us via email as we do have a few available

Compact and feature-rich, our MS-1’s lighter weight means more comfort and energy for done-in-a-day outings such as adventure racing, climbing, short ski tours or just walking around town. It offers a full-featured, ultra-comfortable design in a versatile and ventilated day-pack, offering highly efficient and accessible storage options, while exhibiting a simplified fit and upgraded style and materials.
