Merino base layer

Stealth

Noticed by nobody, including you.

Stealth

Thermal underwear has a reputation.

Traditional base layers fit poorly, and modern base layers feel needlessly tight. Stealth is something else entirely: an unnoticeable, thin and light layer that is also warm.

An ordinary morning, wet and rainy

Getting wet does not matter

Then eight hours in an office with the heating on. Same shirt, same layer underneath, all day.

Worn alone

Some days it is the outfit.

The Highland Smoothshell™ in Stealth responds to both your body temperature and the temperature outside. It feels warm and dry in cool air, but doesn't raise your body temperature in warm weather either, whatever your body type or what you wear it for.

When you stop. Still

When you stop.

When you don't. Moving

When you don't.

Highland Smoothshell™

Merino outside, ECONYL® inside

The wool keeps the warmth. The side against your skin is the reason you forget it is there. How the two become one fabric is on the materials page.
