Men's Thermals
Long johns and thermal sets for cold weather.
Base layers for cold weather. A thermal works by trapping air against the skin, which only happens if it fits close — a loose thermal is just an extra layer, not a warm one.

What to check
- Fit — close to the skin, or the insulation does not work
- Fabric — brushed insides hold more warmth
- Seams — flat seams matter more under other layers
Sizing
Sizing follows waist measurement rather than the size you usually buy — cuts are graded differently between makers, and two pairs labelled the same can sit very differently. The measurement for each style is on its product page.
