The Nimbus V2 Boot is the boot of choice for backcountry riders who chase the best snow, venture deep into untouched terrain, and are equipped for the harshest conditions.. Featuring a removable inner boot with 1200 grams of insulation, the Nimbus V2 is our warmest option, perfect for the coldest days and easy to dry for multi-day adventures. The Nimbus also uses a double Boa closure system for a custom fit. Built with the same rugged construction and durable rubber outsole as the Cordus, it’s designed to withstand harsh abrasions from your running boards. As with all of our boots, the Nimbus V2 passed a rigorous 14-hour waterproofing test. Designed to endure the toughest environments, the Nimbus V2 delivers the warmth, durability, and supportive fit you need to face any challenge the backcountry throws at you.
