The chest sizes listed in the chart below are from Klim’s chart and I’ve double checked the actual jackets against the chart and it is accurate. But be careful… while the size Large is exactly what you’d expect with a 44” max chest, the smaller sizes are a bit smaller than normal and the bigger sizes are bigger than normal. For example, a men’s size Medium usually is styled with a 42” max chest and Klim’s medium is a 40” max chest. Same goes for larger sizes… an XXL is typically a 48” max chest, but Klim’s is a 52” max chest.
Given the variation from “normal” for smaller and larger sizes, I’d highly recommend you measure yourself and/or measure a jacket that fits you well (take the link below on how to do that). Then choose a jacket that is big enough for your chest.
This jacket is geared toward more off road use than on road, so the cut is just slightly different. I find the body to be just a bit more roomy than their other jacket styles. I found the belly area in the jackets to be the same max dimension as the chest.
Overall sleeve and torso lengths are generous and will work for most average height or taller riders. Those of shorter stature may find the sleeve and torso lengths to be longer than ideal.
