BRING IT ON. Dont let the threat of rain keep you from ridingor, even worse, make you ride your trainer. Weve used our ex ceptional high stretch but lightweight Torrent waterproof fabric and engineered a seam sealed jacket that easily stuffs in a jersey pocket. It will keep you totally dry from the outside, and the stretch fit makes it comfortable and aero. You will give up some breathability compared to our Pocket Liner or Muur jackets, but this is the ideal jacket to bring along when rain threatens.
