Measure around the fullest part of your chest with a soft tape, arms relaxed. Compare with the chart below.
Chest measurements (inches)
- XS 33–35 · S 35–38 · M 38–41 · L 41–44 · XL 44–47 · XXL 47–50
Between sizes?
The Hollow Pine down jacket and Talus Rain Shell have room for a fleece underneath. If you like to layer a lot, size up; for a trimmer fit over a base layer, stay with your usual size. Merino base layers are close-fitting by design.
Sleeve length
Shells and down jackets are cut with a little extra sleeve so your wrists stay covered when you reach for a trekking pole. If you have shorter arms, the adjustable cuffs take up about an inch.
