Gay Men’s Underwear

Underwear made for confidence, comfort and self-expression

Gay men’s underwear is not one specific cut. It is a point of view: a better fit, a stronger silhouette and the freedom to choose what feels right for you. This collection brings together men’s thongs and G-strings, open-back jockstraps, low-rise bikinis, trunks, briefs and men’s bodysuits in everyday, sheer and statement-making styles.

Start with the occasion. A supportive brief or trunk works well under daily clothes. A thong keeps lines minimal beneath fitted pants. Jockstraps offer front support with an open back, while bodysuits create a smooth, body-hugging look that can be worn alone or layered. If you want more definition in front, explore our bulge-enhancing underwear with contoured pouches and stretch fabrics designed to shape without bulky inserts.

Fit matters more than the label on the waistband. Check the size guide on each product, consider the rise and pouch shape, and choose the larger size when you fall between measurements. Product pages identify the fabric, cut and care instructions so you can compare styles without guesswork.

Justin+Simon is owned by MaleBasics. Our house brands are designed and made by our team in Colombia, where we develop the fit and construct each style in our own factory. The wider collection also includes selected independent labels; each product page clearly identifies the brand and manufacturing details available for that item.

Build a useful rotation instead of choosing every pair for the same purpose. Keep a few dependable everyday cuts, add lower-coverage options for fitted clothing, and choose expressive fabrics when you want the underwear to be part of the look. For a more sensual direction, continue to men’s lingerie; for reduced-price options, check the sale collection.
