Description

The CASTELLI PR 3 SPEED SUIT triathlon suit White/Black is Castelli’s fastest race suit. Its design, developed using computational fluid dynamics (CFD) analysis, optimises fabric and seam placement to reduce drag in the racing position.

The upper is made from ultra-lightweight 50-denier fabric, the thinnest and smoothest Castelli has ever used. The ribbed sleeves reduce CdA at race speeds, while mesh inserts under the arms help manage moisture.

The KISS Tri chamois provides comfort while swimming, cycling and running. The suit has a full-length front zip and pockets for carrying nutrition. Close fit, for warm conditions between 18 and 35 °C.

Measuring your hips: keep the tape measure level and measure around the widest part of your hips, with your feet together.
Measuring your inside leg: using a pair of trousers that fits you well, measure from the crotch seam to your ankle bone.
If your measurements fall between two sizes, we suggest choosing the larger size for a better fit.
