Got it mainly for use as lightweight sun hoody. The Motiv fabric is similar to Capilene, but softer feel. My Terramar Transport LS tee is also very similar fabric with the light grid pattern.
Had a chance to use on a few day hikes recently in sunny 75 degree weather. Wicks and dries really quick, hood provides good coverage and allows some airflow. Was concerned about durability of fabric, but no abrasion from the straps of my Talon 22. Went through some narrow brushy trail at times, but did not snag on anything. Not reeking, but some perspiration smell, could use a wash at this point.
Got it on sale at ULOG. Large, ink color, have worn next to skin and with light tee under. Seams are nicely done, very comfortable. Regular fit, not too loose or tight on me (42 chest).
