Sizing for Ostroy

We have not yet published a measurement chart for Ostroy. If you are between sizes or new to the brand, contact us with your measurements and we will check the garment for you, or visit the Adelaide showroom.

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.

Compare every brand side by side in our full size guide, or visit the Adelaide showroom to try before you buy.
