Key Takeaways

Get set to upgrade your undies as we discover the best trunks for men. After poring over dozens and dozens of customer reviews, I’ve come up with the following list of best men’s trunks. In this guide, I’ll be looking at a range of designs, focusing on comfort, style, and functionality in order to separate the good from the bad. Whether you’re a seasoned trunk enthusiast or a rookie, together we’ll navigate the vast landscape of choices and highlight key styles such as CDLP’s antibacterial pair and the wallet-friendly option from Fruit of the Loom.

Why it’s great: The only thing that impresses more than CDLP’s creative eye is the awesome underwear that they sell. Simple, stylish, and oh-so soft, each pair is worthy of a place in any guy’s rotation. The boxer trunk is a super breathable style that offers silk-like softness and natural moisture-wicking properties. It comes with a low waist, short leg, and the label’s signature waistband stamped with CDLP branding.

How it feels: Made from a lyocell-blend fabric, these trunks have a seriously soft handle, with a hint of stretch for ultimate comfort. They’re breathable, antibacterial, and durable, promising to maintain their shape for a rather long time.

Flaws but not dealbreakers: For one pair of undies, they’re quite costly (but worth it). However, if you decide to invest in a few pairs, you’ll save up to 20% off.

Sizes Available: XS-XXL | Colors Available: 6 | Material: 95% Lyocell, 5% Elastane

Why it’s great: Whether you’re big or small, budget trunks are a possibility thanks to Fruit of the Loom (and you don’t have to sacrifice style or comfort either). These mid-rise undies are made from a breathable micro-mesh fabric that wicks away moisture and keeps you cool and dry. They’re cut shorter at the legs for a fantastic fit, while there’s a soft, flexible waistband for ultimate comfort.

How it feels: Soft, stretchy, and supportive, these best men’s trunk underwear feel great. Better yet, they stay just as comfortable (if not better) after every wash.

Flaws but not dealbreakers: Some customers have claimed they come up smaller than other similar options available. You may want to size up if you usually find your underwear quite tight.

Sizes Available: S-XXXL | Colors Available: 4 | Material: 57% Cotton, 38% Poly, 5% Spandex

Why it’s great: There’s a reason every man and his dog owns a pair of Calvins—they’re an iconic underwear choice that’s not just soft but impeccably cut and super stylish. These trunks for men are made from a stretch-cotton fabric that keeps your privates fresh and firmly in place. There’s a functional fly and contoured pouch, plus the label’s instantly recognisable logo waistband.

How it feels: Silky smooth, they’ll feel comfortable from day until night. In terms of fit, they’re designed with a full rise, so sit comfortably above the hip and fairly high on the thigh.

Flaws but not dealbreakers: Though they can be thrown into the tumble dryer, you should hang them to dry to extend their lifespan.

Sizes Available: S-XXL | Colors Available: 10+ | Material: 95% Cotton, 5% Elastane

Why it’s great: These truly best mens trunks help you bid adieu to wedgies thanks to the four-way stretch fabric that moves with you instead of seeking solace in your crack. They’re made from a performance-cooling fabric that wicks away moisture and dries faster than a rat up a drainpipe. Better yet, there’s no tags on the waistband and the seams are designed for zero chafing.

How it feels: Lightweight and stretchy, these seriously soft trunks are as comfortable as it gets—fitting snugly without feeling too tight.

Flaws but not dealbreakers: Trunks are generally cut quite high but this pair feels particularly short.

Sizes Available: S-XXL | Colors Available: 10+ | Material: 85% Polyester, 15% Spandex

Why it’s great: Life’s too short for uncomfortable underwear, so do the smart thing and invest in Lacoste’s stretch-cotton trunks. An excellent option for every day, they feature a contour pouch to keep your bits happy and a branded waistband that sits comfortably at the hip.

How it feels: There’s enough stretch for optimum mobility and the fabric is beautifully soft.

Flaws but not dealbreakers: The assortment of long tags inside are slightly annoying. I’d suggest cutting them off for improved comfort.

Sizes Available: XS-XXXL | Colors Available: 10+ | Material: 95% Polyester, 5% Elastane

Why it’s great: adidas’ stretch trunks for men are designed with the active lifestyle in mind, but they’re just as effective for daily wear. Made from a breathable mesh fabric for support and maximum ventilation, they offer unrivaled comfort whether you’re working out or running errands.

How it feels: Soft with plenty of stretch, they have a tagless waistband and streamlined stitching for superior comfort.

Flaws but not dealbreakers: If you’re used to wearing boxer shorts or briefs, it may take a little while to get used to the higher cut. These sit around the top of the thigh.

Sizes Available: S-XXL | Colors Available: 3 | Material: 91% Polyester, 9% Spandex

Why it’s great: While Shinesty doesn’t take itself too seriously, the brand’s underwear is no joke. Featuring a supportive and ‘enhancing’ pouch, these ball-pleasing trunks help to keep everything where it should be. They’re made from a breathable, moisture-wicking fabric that’s soft and has a hint of stretch for unbeatable comfort.

How it feels: Softer than a baby’s backside, the fabric is arguably smoother than cotton and has the ideal amount of stretch. They feel supportive enough and definitely don’t itch.

Flaws but not dealbreakers: They’re quite pricey but you can get them cheaper should you wish to sign up to the Shinesty subscription service.

Sizes Available: S-5XL | Colors Available: 14 | Material: 95% Modal, 5% Spandex

Buying Considerations for the Best Men’s Trunk Underwear 

Fit

The first commandment in the Book of Underwear: Thou shalt not tolerate wedgies. When on the quest for the perfect pair of trunks, prioritize the fit. Look for a pair that cradles your assets like a hammock rather than strangling them half to death. Remember, comfort is key, and you don’t want your underwear waging a war against your well-being.

Material

To find the best trunks for men, you’ll need to choose a comfortable material. Your downstairs deserves the VIP treatment, not a sauna experience. Opt for breathable fabrics like cotton or moisture-wicking blends that can handle the day-to-day chaos without you needing to reach for your ball deodorant or powder.

Style

Gone are the days when underwear was relegated to the shadows of fashion. Today, your trunks are as much a style statement as your favorite pair of jeans. Don’t just consider the cut, but the color and design. Because why settle for boring briefs when you can strut your stuff in something far fancier?

Why You Should Trust Us

In my experience, both as a writer for Fashionbeans and many years of wearing different types of underwear, most men find something they like and stick with it. And while this fail-safe method is as comforting as a thermal shirt, it also means you could be missing out on something better.

Alongside boxer briefs and the odd pair of thermals, I’ve been wearing trunks for the good part of a decade. Which is why I’ll tell anyone who’s willing to listen that they need to give them a try. To further fight my cause, I’ve sought help from hundreds of reviewers that are also flying the flag for the best men’s trunk underwear around.

Final Verdict

As I finish my deep dive into the best trunk underwear, one thing is abundantly clear: great trunks deserve a place in every men’s daily rotation. And whether you’re looking to fully commit to this thigh-grazing style or simply want to add a few pairs to your undergarment arsenal, CDLP’s version should be at the top of your wish list. Classic, easy on the eye, and silky soft, they’re a must-have for every guy—regardless of size or sartorial preference.
