Great price & does a great job. Is snugger than other brands in the same size. Returned for the next size up which was a better fit. The material initially feels a little like neoprene rubber v. other brands feeling like cloth. Didn't notice it after wearing it during the day. Arm/sleeve openings from shirt body need to be larger. Seams cut into armpits.
