A Dakine Thrillium S/S Jersey should be included in every DH bike purchase. It's not required to get in the lineup at Whistler, but it will help calm your jitters knowing you're on point fashion-wise. This jersey has raglan sleeves and a slightly loose "gravity cut" that's perfect for riding, and the odor-control treatment allows you to go straight to the post-ride patio session without a costume change.
