The Wolf Tooth Singletrack Pogie were developed over several years in the cold Minnesota weather. There are three key features that set these pogies apart from the pack: easy hand access, adjustable warmth, and quick install/remove. The adjustable cuff allows you to adapt the warmth of the pogie based on the weather conditions and how hard you are working. With the cuffs up and the zipper closed your hands and forearms are covered for maximum warmth. With the cuffs folded down the hand opening flares open and provides coverage up to your wrist...enough coverage to shield your hands from the elements but open enough get your hands in and out quickly when needed. You will appreciate this feature if you've ever had a face full of snow because you couldn't get your hands out of your pogies fast enough in a crash. Includes our exclusive quarter turn bar plug attachment for fast and easy install/remove — plus they keep the pogies perfectly positioned on your handlebars.
