The coffee has a wonderfully soft and light knitted jacket that gets extra warmth from the coffee. With a smooth exterior and a warm brushed interior, the sweater is warmer than regular fleece. Carbon is used in the intermediate layer material of the sweater, which increases the warmth of the fabric, reduces electricity and odors. Coal, on the other hand, is obtained from used coffee grounds. The knitted jacket is easy to put on and perfect under rain and shell clothes.
