The 2L Performance Bib is built for serious snow days, combining a 20,000mm/15,000g waterproof-breathable stretch shell with fully seam-taped construction to keep moisture out. A grid mesh fleece lining along the legs adds warmth and comfort, while PAS® thigh vents allow active heat management during high-output runs. Elastic shoulder straps and back-waist adjusters dial in the fit, and a zippered drop-seat panel with a magnetic snap simplifies layering access. Zippered pockets and silicone-grip boot gaiters round out the functional details.
