- Insulating Thermolite® technology
- Moisture-wicking interior
- Casual fit & length
Powered by Thermolite® technology, our lightweight flannel is engineered to trap heat, but release moisture—so you’ll stay warm and dry all weekend.
Materials & care
- 75% Polyester / 21% Thermolite® Polyester /
4% Merino Wool
- Machine wash cold. Do not bleach.
- Tumble dry low. Cool iron if needed.
Our blend is powered by Thermolite®, a hollow-core fiber that traps heat without adding weight. To make sure you stay comfortably dry, we also added moisture wicking to the interior. Then we brushed our flannel for a soft, smooth feel.
