The orginial bearpants are made of a very high-quality, high-tech fleece fabric, with high quality stitching.
My manufacturer makes high end clothing for a number of European clothing companies and I insisted on using high quality materials.
The goal, obviously, was to make them look like bear fur, hence the name, Bearpants. Do not worry, they are 100% fleece and no bears were actually harmed.
Washing Instructions: Machine wash cold like delicates, and tumble dry low with delicates.
