Men's Trunks

Scroll through the best range of men’s trunks from all the top brands to find the style that is right for you. Men’s trunks are undoubtedly our most popular style of men’s underwear. Key features to look out for are a pouch at the front to help keep everything in place and a leg cut to sit at the top of the thigh, so fabric is unlikely to bunch up. Made from either cotton or modal (a breathable fabric that wicks moisture away) trunks also contain a touch of elastane to help give a smooth and extra comfortable fit.

Men's trunks FAQs

Scroll through the best range of men’s trunks from all the top brands to find the style that is right for you. Men’s trunks are undoubtedly our most popular style of men’s underwear. Key features to look out for are a pouch at the front to help keep everything in place and a leg cut to sit at the top of the thigh, so fabric is unlikely to bunch up. Made from either cotton or modal (a breathable fabric that wicks moisture away) trunks also contain a touch of elastane to help give a smooth and extra comfortable fit.

How do trunks differ from other men’s underwear?

Trunks take inspiration from the styling of a boxer brief, but will have a much more square shape on your body due to their significantly shorter leg length, offering less material coverage. They operate, effectively, as a mid-point between a traditional brief and a boxer brief - with briefs having no leg material at all and boxer briefs extending down to just over half-way down the thigh. Trunk legs should extend to about third of the way down your thigh. Otherwise, they offer the same level of comfort and support as a pair of boxer briefs - holding your package softly in place, while giving you a bit of material length on the leg to play with and help fight the chafe. If you would like to know more about men’s underwear types and the differences between them, you can check out our handy article on men’s underwear types right here: https://pantsandsocks.com/blogs/post/mens-underwear-types

How should men’s trunks fit?

Men’s trunks should fit snugly on your body but should not be tight in any area. The material should sit close to your skin so everything is comfortably held in place - including the crotch area. You should feel comfortably contained within the material. There should not be any pinching or tightness at all across the trunks - especially at the waistband. You should be able to easily slip two fingers between your skin and the waistband. No matter the thickness of the waistband on your trunks, it should never be digging into your skin. The same goes for the leg holes. If you find that the leg holes dig into your thighs, you’ll need to go for a bigger size.

What size trunks should I get?

From XS to XXXL, each size of trunk will correspond to a size range in inches. As trouser waist sizes in the UK are usually measured in inches, you can look at the inside label of your most comfortable pair of trousers to find out your waist size in inches. Then, all you need to do is look at our size guide found on each of our product pages to see what size trunks you should buy. Different brands will have slightly different size ranges, but don’t worry - the size guide on each of our pages includes dimensions for every brand we offer, so you should be able to grab your perfect-sized trunks without any issues. Don’t forget to not skip this step!

How do I choose the best trunks for me?

This one all comes down to personal preference. While most trunks will operate in the same way on a purely mechanical level, you may want to experiment with the different aesthetics provided by the different brands we offer at Pants&Socks. Some favour vibrant patterns, prints, colours and designs, while others have thicker waistbands, a variety of soft materials used in their construction or a focus on providing even more support for your package. The only way to find out is to try different brands and see which best suits your needs. You can check out reviews of the brands that we stock at Pants&Socks on our Below the Belt Blog for more information on which brand may suit you best: https://pantsandsocks.com/blogs/post
