The draw: No drag (OK, almost)
This suit has quite a heritage. Sebastian Kienle wore it to Kona glory in 2014, and Andrew Starykowicz wore it to set Challenge Roth’s bike course record. The RS1 feels as fast out of the water as it looks, with a comfortable chamois that’s thin enough to disappear during the swim and run, and that never chafed during testing. The super-aero profile—which includes a place to tuck in the zipper pull—means you won’t find any pockets. So if you’re a pack rat on long-distance days, the RS1 isn’t for you. Rubber grips on the sleeves and legs keep them from riding up.
