Size Guide

Harness Sizes

Our harnesses are made from a premium, soft-touch elastic that has a natural amount of give, to comfortably fit a range of chest sizes. We use a standard chest measurement with arms resting by the side of the body as the basis for our harness sizing. All harness straps that extend down to the waist come with sliding adjusters, so you can easily set the perfect fit.
