The Mechanism Deep Winter Long Bib combines light and advanced 2 and 3-Layer Schoeller fabrics for both protection and insulation in a pair of high-performing bib tights. Without adding bulk, the Mechanism Deep Winter Long Bib lends your muscles protection from the elements. The low-profile grid structured back of the fabric insulates and allows heat to escape the surface of your skin when the pace goes up. Perfect for high-intensity training and racing.The tights are kept in place with soft straps and a mesh back panel, creating the best possible conditions for your base layer and outer layers to work with you. Reflective details give extra visibility when riding in the darker months. Finished with our signature ultralight foam chamois used in our regular Mechanism Bib Shorts.
