The Pas Normal Studios Mid Sleeveless Base Layer is a crucial component for effective layering in winter cycling. Serving as an alternative to the Heavy Base Layer, it offers the benefits of Polartec Power Wool fabric, tailored for milder days. This sleeveless base layer is highly versatile, making it easy to integrate into both summer and winter apparel. Constructed with a merino wool interior and a synthetic fiber exterior, it provides a hybrid approach to moisture control, breathability, and durability. The merino wool adds natural odor resistance, while the high-efficiency grid backer traps warm air and supports quick drying, ensuring optimal comfort and performance.
