This soft and stretchy jock has an internal pocket and a reinforced O-ring that will accommodate most soft packers (packer not included). The pocket has a 2-panel design that will accommodate most STP packers. Machine or hand washable in cold, line dry. 95% Cotton, 5% Spandex.

Available in five sizes: XS/Small (fits approximately 27"-29" waist), Medium/Large (fits approximately 30"-33" waist), Large/XL (fits approximately 36"-40" waist), XL/2XL (fits approximately 41"-46" waist), and 2XL/3XL (fits approximately 47"-52" waist).

A quick way to determine your best size is to grab a pair of underwear that fit you well, and lay them flat on a table to measure their waistband width.  Then you can choose the size that best matches from the following flat measurements:

XS/Small: 13" wide waistband when measured flat
Medium/Large: 15" wide waistband when measured flat
L/XL: 17" wide waistband when measured flat
XL/2XL: 19" wide waistband when measured flat
2XL/3XL: 21" wide waistband when measured flat

Please note: This will fit most soft packers, like the Mr. Softie, the Pack It, all the Packer Gear Packers, the Archer, the Pierre, Sam the STP, and the STP Fitz. However, the stitching pattern on the jock is such that fitting a packer with very large balls (like the Mr. Right) will be difficult-- the Boxer Brief version of this product does have additional room for the balls, so if you're trying to fit a Mr. Right, you might want to go with the Boxer Briefs.
