100% Microfiber Imported COVETED APPROVAL: Denali’s men’s 100% microfiber long sleeve ProtectUV Teaser shirt carries the rare MIF Seal of Approval and is recommended by the Melanoma International Foundation. STAIN RELEASE: Our Zyptron Stain Release system will keep your Denali Teaser shirts looking fresh regardless of the outdoor muck you get into. MOISTURE WICKING: ProtectUV fabric will disperse moisture through our WiKZ technology and allow it to evaporate rapidly. This quick rate of evaporation provides the cooling effect your body needs during hot days in the sun and periods of strenuous activity. MULTI-SPORT SHIRT: The Denali Teaser long sleeve shirt is your go-to for your at-home activities including gardening, yard work, playing with the kids outdoors, or just relaxing in a hammock in the sunshine. Whether worn on its own or as a base layer, the Denali Teaser performs. MEGA SOLAR SHIRT: We test our Denali Teaser shirts through an independent lab to assure compliance with AATCC 183 for UVA and UVB blockage to the 50+ level, the highest measurable blockage of harmful UVA and UVB rays. Teaser shirts are recommended by Melanoma International Foundation.
