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.
The Stealth base layer
Shirt and pants, for him and for her.
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.
When you don't.
Highland Smoothshell™What Stealth is made of
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.
