You don ’ t realize how much you need a heated base layer until you have one! It ’s been such a benefit to various aspects of my life. I wear it beneath my layers when spending time outdoors during winter in Wisconsin. But I ’ ve also worn it to work( in an office) during especially cold days. It fits true to size and is comfy. Somehow it seems to trap heat inside yet it ’s also breathable, I don ’ t sweat in it like I have with other base layers.

The Base Layer Shirt takes the bite out of any cold day! And the battery last for hours! Washed it in a cold wash then hung it to dry, easy peesey! Definitely worth it!
