Best Men's Underwear for Your Body Type
Share
Finding the right underwear isn't just about style — it's about fit. The wrong cut for your body type can be uncomfortable, unflattering, and just plain annoying. The right one? Game-changing. Here's your guide to finding the best men's underwear for your build.
Best Underwear for Slim Guys
If you're on the leaner side, you want underwear that adds shape and definition rather than drowning your frame. Briefs and trunks are your best friends — they hug your body and create a more defined silhouette. Look for styles with a contoured pouch that adds volume at the front. Avoid loose boxers, which can make slim frames look shapeless.
Best styles: Briefs, trunks with contoured pouch, fitted trunks
Best Underwear for Bigger Guys / Larger Builds
Comfort and support are key for larger builds. You want a waistband that doesn't dig in, a roomy seat, and a supportive front pouch. Trunks and boxer briefs with a longer leg are ideal — they prevent thigh chafing and stay in place throughout the day. Look for moisture-wicking fabrics to keep you cool and comfortable.
Best styles: Trunks, longer-leg boxer briefs, supportive briefs with wide waistband
Best Underwear for Muscular / Athletic Builds
If you've got muscular thighs and glutes, standard underwear can feel restrictive or ride up constantly. Look for trunks with stretch fabric — at least 10% elastane — and a longer leg that stays put. A structured pouch is also important to accommodate your build comfortably without feeling compressed.
Best styles: Athletic trunks, sport briefs, jockstraps for training
Best Underwear for Average / Regular Builds
Lucky you — almost everything works! The key is finding what you personally find most comfortable. Trunks are the most universally flattering style, sitting mid-thigh and working under most clothing. If you want something bolder, briefs are a great option. If you prefer more coverage, go for longer trunks.
Best styles: Trunks, briefs, tanks & vests for layering
How to Get the Right Size
Whatever your build, sizing correctly is crucial. Too small and you'll be uncomfortable all day. Too large and the pouch won't hold its shape. Always check the brand's size guide and measure your waist rather than going by trouser size — they're often different.
The Bottom Line
The best underwear for your body type is the one that fits well, feels great, and makes you feel confident. Don't be afraid to try different styles — you might be surprised what works best for you.
