The sleek, non-bulky design allows it to fit comfortably under mid-layers or heavy outerwear without restricting your range of motion.

Care & Safety

This high-quality Merino wool is designed to be machine-washable and is engineered to resist deforming or losing its shape. To maintain the integrity of the 19.5-micron fibers, it is recommended to use a wool-specific detergent and a gentle cycle. Avoid using bleach or fabric softeners. For best results and to preserve the 4-way stretch, air dry the garment flat and keep it away from direct high heat.
