Core Tri Shorts - Women's

If you're dipping your toes into the multi-discipline world of triathlons, then you've probably already determined that tri jerseys aren't much different than their road counterparts. They're a bit tighter, maybe, with a bit less (or more) sleeve, but ultimately interchangeable. Triathlon shorts, on the other hand, are a radically specialized affair, and despite Castelli's relatively new status in the world of triathlon kit, few specimens illustrate this fact better than the Core Tri Shorts.

The shorts' body is made from Pace 3 material, which is compressive for aerodynamic and muscle stabilizing purposes. It also dries quickly for a comfortable transition from swim to bike and an ongoing defense against irritating moisture build-up through the run leg. The shorts also incorporate Castelli's speed hooks, which allow you to link the back of the shorts to compatible jerseys for a fit that mimics a body suit's aerodynamics and coverage without the corresponding restriction of movement.

The included Kiss3 Tri seat pad is also designed with triathlons in mind, and it's the same insert used in Castelli's Rosso Corsa line. It eliminates any excess material for a minimalist chamois that maintains the support you need on the bike while all but disappearing during the swim and the run. Its soft outer layer stretches to move with you whether swimming, running, or cycling, and its minimal bulk also makes it the fastest drying chamois in Castelli's line, so you'll be riding dry by the time you leave T1.

If your Core Tri Top's two pockets runneth-over with spare tubes and CO2, the Core Shorts' rear envelope pocket gives a bit more room for easily-accessible gels so you don't have to resort to strapping a parachute-shaped bento box to your top tube or tucking them into your leg bands. The latter benefit is especially welcome, since the Core Shorts feature a lie-flat elastic leg band, which grips for a secure fit without creating a transitional ridge to catch the wind.
