Standard Sizes

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.

Notes:

  • Down suits are sized to fit over thermal underwear 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.
