We poured blood, sweat and beers into the creation of our most extreme coolers ever. Influenced by Slayer — the masters of thrash metal — this wearable 6-can single-barrel sling cooler bag channels Reign in Blood, the band’s boundary-pushing third album and arguably the greatest speed metal album of all time. (And by divine invention, this can matches the Reign in Blood KoolTunes, Playmate Classic and 16 Oz Can.)
