Don't let winter weather hold you back from enjoying your favorite backcountry trails or city routes. NORU’s tri-layer fabric ensures warmth without causing you to overheat. Layer this piece over your casual attire and under your protective gear for optimal comfort. This non-restrictive, fleece-lined jacket zips on and off easily, allowing for quick adjustments. For milder conditions, you can convert it into a vest by detaching the sleeves, focusing warmth on your core. Additionally, the thumb openings in the sleeves prevent them from twisting and keep cold air from creeping up your arms, ensuring a snug and warm fit as you move.
