Size Guide

Find your perfect fit

Most of our jackets use Asian sizing and run about one size small. To get the fit you expect, order one size up from your usual US size.

Exception: the Summit Fleece-Lined Jacket is labeled in US sizes (M = US 38, L = US 40, XL = US 42, 2XL = US 44, 3XL = US 46–48). Order your usual size, or one size up if you want room for a sweater underneath.

How to measure

  1. Chest: measure around the fullest part of your chest, under the arms.
  2. Shoulders: measure from one shoulder seam to the other across your back.
  3. Sleeve: measure from the shoulder seam to your wrist.
