Review on Optimized: Under Armour Women's ColdGear Compression Mock for ultimate performance by Jason Robinson

I bought this shirt for a hike I was going to do in the mountains of Vermont where I knew it would be a bit chilly. I'm 5ft 3in, 160lbs and would describe myself as of average build. I usually wear a size M for most things but based on the feedback on this shirt I decided to go for a size L which can be too tight. I'm not exactly sure what I look like, so I definitely didn't want something that would tighten my skin or physically restrict my range of motion while hiking. The outside is typical Under Armor material, with a softer, almost fleece-like material lining . . the inside is very thin. I was a bit skeptical that this would be enough to keep me warm, but (especially when combined with other items) it did a fantastic job of keeping me warm without breaking out in a complete sweat. Although it is softly lined, it absorbs moisture like normal Under Armor and prevents you from sweating heavily or smelling badly.
