This is my favorite fabric for designs that require a nice level of shine but remain one hundred percent functional in the cold. The compression on this fabric is medium, and the interior is soft to the touch, like fleece. The exterior shines across various planes: Whether it’s in sunlight or indoors, it will provide your musculature with sheen. It allows full movement for athletic activities because it stretches horizontally and vertically. It will keep you warm in colder training runs, rides and lifting sessions to protect muscles. Recommended for activities under 40F. If you’re headed outdoors, this is the fabric you want.
