Starting with a good baselayer is a necessity. A bad baselayer means moisture is stuck against your skin, which is the last place you want it. Wet skin means cold body. For this reason, we recommend merino wool. Wool is a natural fiber made to keep sheep warm in the winter, so why wouldn’t it do the same for you? Merino wool is the softest, smoothest wool available, meaning it’s the most comfortable to wear against your skin. Forget the itchiness of your grandmother’s layers, this is soft and warm.
Wool is naturally anti-micorbial, which means you’ll have to work pretty freaking hard to make it smell. While wool holds onto moisture longer than polyester, polyester stinks and its warmth retaining characteristics leave much to be desired. Combine them and you get the best of both worlds with a little added stretch and shape retention.
Lastly, make sure your baselayers fit snug, though not so tight they are restrictive. Keeping the material against your skin will ensure the moisture moves away from your body as quickly as possible, which is the goal of the entire layering system.
The North Face Stretch Softwool tee and tight are a lightweight merino/nylon blend that is comfortable on both warm and cold days.
