Try this wool.
This medium thick 100% Merino wool interlock knit is perfect for all base and midlayer clothing. It works for both active sports and providing warmth over a long period of use. Merino wool does not scratch, keeps you warm even when damp, and is odorless. The great 2-way stretch of the material does not limit your movement.
You don't have to wash this fabric as often as artificial fibers. Airing usually is enough.
