Castelli Core Tri Top and Shorts

$70 and $80 (respectively),

The draw: Short-course speed—and style points

Testers loved the sharp, Euro-cool look of this kit, with the top and shorts cut just a bit shorter than the rest. Super-silky material makes it look expensive and feel comfortable while “speed hooks” (we’d call it Velcro on steroids) on the back lock into the top of the shorts to keep the top from riding up and create a more aero profile. Side-access back pockets don’t take on water while swimming, making this the only two-piece kit testers would swim in without a wetsuit.
