Castelli Men's Core Tri Suit Short Sleeve

Castelli size chart

Castelli figures are the maximum body measurement for that size. Read down to the first number you are under. Jackets built to layer over a jersey (Perfetto, Gabba, Alpha) run closer to true than the rest of the range.

Men's and unisex

How to measure

• Chest: under your arms, around the fullest part, arms relaxed at your sides
• Waist: around your natural waistline, tape held loose
• Hips: around the widest part
• Inseam: from crotch to floor, no shoes

Measure over the underwear you would ride in and keep the tape horizontal. All measurements refer to your body, not the garment.

Two rules that work across every brand. Buying a jacket to wear over a jersey? Take your normal size or size up. Buying a thermal jersey to wear under a jacket? Size down if you are between sizes and want it close.
