Measure the widest part of your chest, under your armpits and around. Be sure that your arms are resting at your sides.
If the measurement is an odd number add 1" to get the next even number. Then refer to the size chart below. Please note all measurements are in inches.
Comment: Nice, but order a size larger than normal. Mine fits nicely with a shirt only, really tight with a light jacket.

New vest, crash test
Comment: I'd had this vest for several days when I took a corner too fast, hit gravel and laid my bike down. The vest protected my body. I got road rash on my arms and hands.
The vest doesn't seem any the worse for wear. I'd recommend this vest for the protection, but seriously consider a jacket for arm protection.
