Changes

Mizuno has a fabric they call 'Breath Thermo' that generates heat, which seems ideal for cold weather clothing[[Running in the Cold]]. The problem with this fabric is that it generates heat from your sweat and if you're sweating, your body is trying to lose heat. So Breath Thermo will generate heat when you least need it and not when you do. From a practical perspective, I tried the Mizuno Breath Thermo gloves and did not find them effective.
