I work year round in Connecticut and spend many of those days outside. During the winter it can get terribly cold in some areas where we work. It may be 20 degrees in the urban area, but 20 miles north on a hill is a different story. Over the past 15 years, working with concrete, I've learned to wear layers. If you go out in the wrong clothes and work hard, you'll sweat all day. It's best to have multiple layers that can be added/removed as needed. Personally, I wear these thermals as a base layer and then a t-shirt, flannel, hoodie, etc. to let sweat build up. They're as comfortable as you could hope for and get the job done well. Not to mention they look great when worn solo. Every year I order another half dozen just to make sure I always have enough. One bad thing I've noticed about this thermal underwear over the years is that it shrinks quite a bit after enough wash cycles. For example, a medium-sized shirt will fit well out of the box and through the first few washes before feeling small. The large ones instantly fit into a larger size, but over time they start to feel like medium. I don't really care because I usually wear them under other shirts. I'd recommend buying one of whatever size you're anticipating and see for yourself where you end up.
