The Public Rec Men's Daymaker Shorts in navy blue are designed for casual occasions with a comfortable and stretchy fabric blend of polyester, nylon, and spandex. These athletic style shorts feature an elastic waist and drawstring closure, along with pockets for convenience. The 8-inch inseam and regular fit make them suitable for summer, fall, and spring activities such as gym training and running. The solid blue color and list of features make these shorts a stylish and practical choice for men size 40 who appreciate a blend of comfort and functionality in their activewear. I know the tag reads 38 but the shorts measure 40.
