Standard Sizing

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

Custom Sizing

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

Notes:

• Down suits are sized to fit over thermal underwear and fleece.
• Shell Suits: D-type suits will fit over down clothing of the same named size: F-type suits will only fit over thermals and fleece.
• The arms of our suit 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 suits differ from street/fashion jackets.
