Wells Lamont Men's Performance Base Layer Thermal Top

This is a size M, thermal performance, base layer top. The top and bottom are sold separately. This shirt appeared to fit slightly big for a medium. If this shirt were worn on its own, it would be fine, but if the purpose of this top was to be worn under another shirt, it would be too big and would likely bunch up under the shirt. I am not sure I would call this a thermal. It is the sweat wicking material and might be nice on a cool afternoon, but doesn't appear to offer a warm layer for a snow filled sledding night. The review on this shirt was mixed from my child. Not sure we are keeping because it would need to be worn on it's own and that is not what we are looking for.
