Looking to buy Men's Underwear?

To remain comfortable, clean and confident, no man can rely on going commando - you need a selection of quality underwear! Whether you’re partial to tighty-whities or extra long long johns, the men’s underwear category at OnBuy is sure to have just what you’re looking for. 

Fits for every man

Our verified sellers can offer you a wide range of different underwear styles. You can select from standards like the micro brief and boxer short to more obscure cuts like hipster briefs and the enigmatically named Tanga brief. Whatever you choose, our selection will keep you (literally) well covered.

As well as a variety of cuts, you’ll also see a great many different styles among this selection. Yes, there are plain white and black men’s underwear for guys who want a classic, conservative look. Men who want more adventure under their trousers can shop underwear with all manner of checkers, stripes in a kaleidoscope of colours, from blood red to neon pink!

You can wear most men’s underwear all year round, but in the winter months it might get a little nippy down under. That’s where our cold weather underwear comes in! We’ve got a selection of ultra cozy thermal underwear and long johns that will keep the cold away from your most vulnerable parts without restricting your movement. 

From stylish to satirical

Not only will you find every kind of men’s underwear in this category, but you’ll also find underwear from top designers. Just because most people aren’t going to see them doesn’t mean you can’t get a set of stylish skivvies!

You’ll find selections from the top men’s underwear brands in our digital clothes shop, including the likes of Dolce & Gabbana, Emporio Armani and Diesel. Wearing one of these top brands underneath will give you a big confidence boost. Plus a set of designer undies lets the select few who do see you with your kit off know they’ve made the right choice!

As well as designer men’s underwear, you can pick up shorts and briefs featuring top pop culture properties too. Many of these men’s underwear choices have subtle designs, like a logo around the waistband, but others have truly striking designers, with riotous colours and illustrations covering the whole package! You can also find a good deal of seasonal and novelty men’s underwear here too - they may be in questionable taste, but they’re certainly memorable!
