How To Measure
For best results, take measurements over your underwear.
Chest: Measure under your arms, around the fullest part of your chest
Waist: Measure around narrowest part of your waist
Hip: Measure around the fullest par of your hips
Sleeve: Measure from the center back of your neck, across your shoulder to your wrist bone
Inseam: Measure from your crotch to the floor
Considerations: Your waist & hip measurements will not necessarily correlate with your actual pant size. Most people wear their pants below their waist, but above their hip. For example if your waist measures 31 1/2" & your hip measures 39 1/2", you would fit best in a M (or 32-33). Also, all of our pants have internal waist adjusters and the bibs are meant to be a bit roomier for fitting layers. Inseams are a bit complicated for the same reason (you wear your pants low on your hips, the crotch drops). Also remember, in outerwear you generally want a longer inseam.
