Is the Thermolator 2.0 a base layer or a mid layer?

It is designed as a next-to-skin base layer. The brushed interior and moisture-venting build work best worn directly under a mid layer or shell.

How warm is the midweight 2.0 version?

It is a midweight top aimed at cold conditions such as skiing and snowshoeing. It runs warmer than lightweight crews, so it suits winter use more than mild-weather activity.

Does it have thumbholes?

Yes. The cuffs include thumbholes to keep sleeves in place under gloves and jackets.

What is ClimaSense thermoregulation?

Does it offer sun protection?

Yes, the fabric is rated UPF 25+ for protection from the sun on exposed snow and rock.

How does it compare with a lightweight base layer?
