Technically this is a piece of equipment, since it will reside in my hockey bag. I had some tongue scraps laying around so I made a coozie. Features you ask? It has a black matte microfiber "upper", 3/8" white felt padding keeps your beverage of choice cool, all sewn up with a Speedy Stitcher. Eyelets on either side for putting a lace through so you can wear it, and yes... it has a 100% carbon fiber outsole. I'm not saying my coozie is better than yours, but...
