Our boxer briefs are extremely comfortable due to their 100% cotton construction. The model is wearing a US Medium (32-34 in.)(81-86 cm.) We have included a reference photo of the boxers in both black and grey. The image will stay the same although the design color may be changed for better contrast depending on the boxer color chosen. Message us for any custom orders or any concerns you may have. *Note: Keep in mind these are handmade and might have slight variances from order to order.
