A range of stadium jackets or varsity jackets have been produced by Tokyo's BackChannel. Four colors are produced in bright purple, solid black, cool grey and Earthy brown. It is almost mandatory to have a patch on the chest or arms of varsity jackets and BackChannel have placed a large "B" on the left chest in matching color with a lion walking infront in light brown. The outer material is a blend of 80% wool and 20% nylon to ensure warmth and lined with 100% polyester inner lining in the same colors. Although the back of the jacket is left plain, the collar, cuffs and waist ribs are detailed with double stripes in two tone.
