How to Measure
To determine hipbelt size, measure around the hips at the iliac crest, not the waist. The padded portion should wrap well around the hips, leaving a gap of 3" to 6" between the tips of both hip pads when securely tightened.
Adjustable and custom packs allow you to make sizing adjustments to the hipbelt.

How to Measure
Osprey running and biking vestpacks come in 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.
