The Pas Normal Studios Mid Long Sleeve Base Layer is essential for effective layering during winter cycling. As a lighter alternative to the Heavy Base Layer, this mid-weight option utilizes Polartec Power Wool fabric, making it ideal for milder winter days. It serves as a perfect foundation for your winter wardrobe. Constructed with a blend of merino wool and synthetic fibers, this base layer offers a hybrid fabric designed to enhance moisture control, breathability, and durability. The merino wool interior provides natural odor resistance, while the innovative grid backer traps warm air and facilitates quick drying. With superior wicking action and high breathability, this base layer ensures comfort and efficiency in various conditions.
