VESTPACK SIZING

Osprey running and biking vestpacks come in a multiple sizes based on chest circumference. Depending on the product, the fit may be gender-specific or unisex, with two or three size options available.

To find your size:
Measure the circumference of your chest at its widest part—across your chest/bust, just below the armpits and around your back. Then, locate your vestpack on the chart below and use your chest circumference measurement to choose the best size.
