I was really surprised how comfortable these are! They feel like a high quality blend of cotton or merino. I found that they are a perfect blend of sexiness and comfort. Sometimes I like to wear them just because they have great support and are more feeing that traditional briefs. Other times it's to feel sexier. And I've worn everywhere from working out to under a suit. Usually jock straps are either just cheap and sexy, or athletic and ugly. These are both!
