To build a durable hunting boot that will stand up to seasons of wear on rough terrain Lacrosse teamed up with a group of experienced backcountry hunters to learn from their insights. After four years of testing and development the result is the Ursa MS a boot designed to get you further into the wilderness. An upper made of SuperFabric and Tec Tuff is incredibly abrasion resistant. A GORE-TEX liner is waterproof and breathable. Designed for mountain terrain the Vibram MONT outsole maintains its performance at low temperatures and stands up to extreme conditions.
