EXTREME WINTER FATBIKING DOUBLE BOOT

THERE ARE NO MORE EXCUSES

Whether you’re heading out on a multi-day expedition or groomed singletrack session, Wølfgar will keep your feet warm down to -25ºF and keep out the harshest of winter days and nights.

Comfort down to -25ºF
Double the insulation of Wölvhammer
Removable felted wool liner boot
Aerogel under foot and over toe
Custom-studdable, 2-bolt compatible Vibram® outsole

Twice the insulation of Wölvhammer means you can brave the most extreme winter conditions and never worry about your feet. The removable felted wool liner boot wicks moisture away from your feet while retaining its insulating properties. On long rides, carry a spare liner to swap out for a fresh, dry pair. Precise placement of aerogel under the foot and over the toe blocks cold and wind from chilling your feet. The 2-bolt compatible Vibram® outsole is custom-studdable to claw into the ice when things get slick. With Wølfgar, there are no more excuses.

Aerogel Insulation

Under the foot and over the toe, we use aerogel, an ultra-thin, compression-resistant and waterproof insulator, to block cold transfer from your pedals and from wind and snow.

Waterproof Membrane

An ultra-thin sheet of microporous material behind our textile shells keeps you dry and warm in the harshest weather conditions.

Merino Liner Boot

Removable felted wool liner boot insulates while wicking moisture away from the skin. On long trips, carry a spare pair to swap out mid-ride

Studdable Outsole

A custom molded Vibram® outsole is two-bolt compatible and studdable with our concave studs and stud tool.

Carbon Fiber Outsole

Our lightweight carbon fiber outsole provides stiffness and better protects against conductive heat loss under the foot.

Premium Insulation

Our footwear uses innovative, premium materials like aerogel, merino wool, and Primaloft® to provide warmth, comfort, and moisture wicking on long rides in harsh conditions.
