Our most competitively priced bike specific jacket uses 2.5 Layer Artex waterproof-breathable fabric and is fully seam taped to keep the wind and rain at bay. A large back vent allows excess body heat to escape. With a choice of bright colors, the Storm Jacket also delivers outstanding visibility. Put on this jacket for a chilly descent or a sudden storm. We've included a matching mesh stuff sack for easy packing, which fits neatly in a jersey pocket.
