Stay warm and dry in the worst trail conditions with the Thermoball™ Insulated Shell Jacket. DryVent™ technology repels moisture to keep you dry, while lightweight Thermoball™ insulation gives reliable warmth without added weight. It performs well in the wet too, so you needn't head home early when a shower passes through. The pre-stretched elastic cuff adjuster, shaped hem, and hood with bonded peak provide added comfort and protection.
