Standard Sizing

The PHD Sizing Chart below is based on measurements without clothing, exactly the way you would buy a shirt or a sweater. A 42" (107cm) chest means that your bare chest uninflated measures 42". Inside Arm is measured from armpit to wrist-bone.

Custom Sizing

Once you've selected a Body Width you can choose Body Length and Arm Length up to two sizes bigger or smaller. For example, a jacket with a medium (M) Body Width can be XS, S, M, L, or XL in Body Length and XS, S, M, L, or XL in Arm Length. If you have any questions about your size, please contact us.

Inside Arm -- can be two sizes up or down from Body Width. Inside Arm is measured from armpit to wrist-bone without clothes. When you measure your inside arm let your arm hang loosely by your side. Don't extend it horizontally.

N.B. PHD clothing is unisex.

Notes:

• Down Jackets are sized to fit over thermal underwear & fleece.
• Shell Jackets are sized to fit over thermal underwear & fleece or light down clothing (e.g. Minimus Jacket): to cover thick down clothing, go up one size.
• The arms of our outdoor jackets are designed to be long enough to keep your wrists warm when your arms are extended horizontally (when using trekking poles, for example) or when you are reaching above yourself (when climbing, for example). In this respect the arm lengths of our jackets differ from street/fashion jackets.
