Its lightweight, highly breathable, moisture-wicking properties make the Traze Amp AFT long-sleeve bike tee the right jersey for all-mountain/enduro mountain bikers. The whole jersey has cooling properties thanks to its brr technology treatment. Brr 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.
