The Reign Tech is the old Glacier tee so if you liked the Glacier, you will like the Reign Tech. The TShirt features an evaporative cooling Polartec Power Dry fabric which is also moisture-wicking to keep you both dry and smelling fresh. Polartec Power Dry Fabric? I have googled this as I didn't know;
Polartec (created for high heat conditions, Polartec’s® innovative line of Delta™ fabrics supercharges your body’s natural cooling system and controls sweat. A raised knit structure traps perspiration to keep you cool without adding weight).
Material: 65% Polyester, 32% Tencel Lyocell and 3% Spandex
