Also wear a helmet if you're trying to triple cork. Seriously.
The DC Dryden Tech Hoody is what Torstein Horgmo was wearing when he did the first triple cork ever. Take that for whatever it's worth. Torstein likes it because it's water-repellent, has a long fit, and has thumb hole cuffs for when you're really getting wild. Double layers at the hood and sleeves make it appear as if you went to work in two hoodies to make one.
