Riddell has launched a new series of NFL licensed collectible helmets. The Blaze Alternate Collection uses teams' current designs but with alternate colors in a new anodized satin finish. These League-approved alternate designs are available in full-size and mini helmets and can be purchased on the League store. Purchase your own at NFL Shop.
I think these are freaking awesome.
