The makings of a comfortable outfit starts with mens trunks from Banana Republic. Often an afterthought when it comes to building a wardrobe, trunks for guys deliver that essential smooth foundation layer that will comfortably support you from morning through night. Choose from a collection of different styles including briefs, boxer briefs, stretch trunks, and more. Whether you only stick to one style or like to change things up depending on what you're wearing, we fulfill all your underwear needs. Your preferred colour choice awaits, including classic white, navy, heather grey, and black. Once you feel how great they fit, you'll put more thought into your trunks going forward.

It All Comes Down To Fit

How well men's underwear trunks fit is as important as a great pair of shoes. Without the proper support, materials, and features, you're bound to be miserable sooner rather than later. Our mens underwear trunks are made from superior quality fabrics such as pima and jersey cotton, that have been combed for extra softness. A touch of stretch offers flexibility and also helps to maintain the fit and durability. Even after repeated wash and wear, they bounce back to like-new condition. The signature elastic waistband rests soothingly around the waist without troublesome pinching or digging into the skin. Looking for extra support? A closed pouch on many of our models do just that.

Men's Underwear Trunks For Different Trousers

The smooth, sleek lines of mens trunks makes them a popular choice to wear under every type of trousers or shorts. Briefs are the classic standard and for good reason: they provide just enough coverage and with your legs free of fabric, you eliminate unsightly bunching and irritating chafing when you're sporting your tighter-fitting trousers. They also provide great support when you're exercising or challenging friends to a game of football. When you're looking for a little more coverage, sports trunks or boxer briefs are the answer. Often described as the love child of briefs and boxers, these body-hugging silhouettes eliminate lines and bumps under many different types of trousers. They're a flattering design that's not too tight, not too lose and feel as great under a suit as they do joggers.

When you fill your collection of undergarments with mens trunks from Banana Republic, you treat yourself to all-day comfort.
