Denali Performance's long sleeve T-shirt Teaser is created from its proprietary ProtectUV Mega Solar UPF 50+ fabric, and carries the coveted and rarely bestowed Melanoma International Foundation Seal of Approval for providing safe sun protection. ProtectUV assures you of superior protection against the sun’s harmful UVA and UVB rays yet leaves you feeling comfortable and relaxed after a day of recreational activities like golfing, playing Frisbee with the kids, relaxing poolside, or even working in the garden in the sun. Denali’s ProtectUV fabric is super soft and is constructed so that the UV protection is a permanent part of the fabric. No matter how hard you play and how many times you wash your Denali shirts, your UV protection will not wash out. Our shirts also feature WiKZ Moisture Management System, which keeps you dry and comfortable in even the hottest climates. In addition, the Zyptron yarn handles all the rigors you put our shirts through so they look fresh and clean after every wash. Denali was awarded the Seal of Approval of the MIF by testing our ProtectUV fabric against the stringent and internationally accepted AATCC 183 guidelines and achieving at least 97.5% blockage of UVA and UVB rays. Thanks to the unique mechanical stretch of our ProtectUV fabric, water and body moisture evaporate in a snap. This keeps you feeling cool and comfortable no matter if you are wearing your Denali Teaser as a base layer for skiing or straight out in the blazing sun fishing for marlin or poling for tarpon.
