Its lightweight, highly breathable, moisture-wicking properties make ION's Traze Amp AFT long-sleeve bike tee for men just the right jersey for all-mountain/enduro mountain bikers. The main body contains brrr® treatment which provides a permanent cooling sensation through active moisture-wicking. On the sides, mesh inserts allow enough cooling air to get inside the jersey when hot. Making sure the jersey fits the body position on the bike perfectly, the Traze Amp LS AFT tee features a slightly longer cut at the back. The collar also features thoughtful paneling to enhance comfort.
