The Flylow Unicorn Mitten starts with a pre-treated, waterproof leather mitten and adds upcycled nylon canvas pulled from Flylow's own pant-production scraps for real added toughness. A 10,000mm waterproof, breathable lining keeps hands dry through deep cold, while zoned Greenloft insulation runs 220g across the back of the hand and 100g through the palm. A rib knit cuff seals out snow at the wrist on every lap. What Our Gearhead(R) Experts Are Saying:"I've dragged these across rock and crusty snow all season and the canvas backing hasn't torn or worn thin. The scrap fabric holds up exactly like new material would."
