Our Top Picks
Why it’s great: In terms of affordability, quality, and comfort, you’re going to find it hard to beat these sweat-wicking boxers from Knocker. They’ve been given a five-star rating by over 2,000 customers and it’s clear to see why—they’ll keep you dry, fresh, and stop everything swinging around. Thanks to their seamless sporty design, you can use them as your everyday underwear choice or save them for exercise.
How it feels: Clearly made with comfort in mind, they have plenty of stretch while providing the perfect amount of support to keep your privates happy. In terms of fit, they’re tight but not restrictive. I find them similar to your favorite pouch styles.
Flaws but not dealbreakers: You can’t put these in the washing machine, so you’ll need to wash them by hand. Thankfully, they dry pretty quickly.
Sizes Available: S-3XL | Colors Available: 10+ | Material: 90% Nylon, 10% Spandex | Style: Boxer Briefs
Why it’s great: If you’re not comfortable spending a fortune on your undies, Hanes’ boxer briefs are an affordable option that don’t sacrifice style or softness. Made from a breathable, sweat-wicking fabric, the no-pinch waistband and tagless back promise to provide unrivaled comfort whether you’re wearing them daily or rotating them with your current underwear line-up.
How it feels: They are just like your favorite pair of thermals, without the annoying tags and excessive seams. The fit feels like a gentle hug more than an excessive squeeze.
Flaws but not dealbreakers: The cotton construction may make them soft, but it also means they lack a little stretch. I’d suggest investing in several pairs so you’re able to wash them less frequently and go longer between wears. It also means they’re less likely to turn baggy.
Why it’s great: Made from a premium micro modal fabric, these breathable trunks wick away moisture and keep your nether regions happy and fresh (you can hold fire on the ball powder). The 3D pouch will support and accommodate larger lads while the soft waistband sits comfortably on the hip.
How it feels: Fine, soft, and lightweight, you may even forget you’re wearing them. They don’t really feel like ordinary boxers—more like a second skin.
Flaws but not dealbreakers: They do tend to ride up a little and are fairly snug. If you prefer your underwear looser, they might not be your perfect match.
Sizes Available: S-XL | Colors Available: 8 | Material: 92% Micro Modal, 8% Spandex | Style: Boxer Briefs
Why it’s great: Suitable for big guys and skinny frame alike, Falke’s wool boxers are thermoregulating, so they’ll keep you warm in the winter and cool during summer. They’re moisture-wicking for cleanliness and mold to your body shape for ultimate comfort.
How it feels: Unrestrictive and beautifully soft, you notice the quality as soon as you slip them on. They feel quite sporty but I find them ideal for daily wear.
Flaws not dealbreakers: Admittedly, the price tag is steep. You’ll need to be working with a pretty generous budget to be able to justify the hit to the wallet. If not, it could be a good idea to pop them onto your birthday or Christmas list.
Sizes Available: S-XXL | Colors Available: 2 | Material: 55% Wool, 44% Polyamide, 1% Elastane | Style: Boxers
Why it’s great: I’ve been turning to Uniqlo for my everyday basics for as long as I can remember, so imagine my delight when I found out they offer some seriously good men’s seamless boxers. Made from AIRism with quick-drying properties (no need for ball deodorant) that’ll also keep you cool, they’re stretchy, soft, and perfectly fitted.
How it feels: Completely seamless, these are super stretchy and feel silky smooth. I find the fit to be just right—not too tight but supportive enough to hold everything firmly in place.
Flaws but not dealbreakers: Uniqlo’s seamless range doesn’t hang around for long. You’ll need to act fast before they sell out.
Sizes Available: S-3XL | Colors Available: 3 | Material: 71% Polyamide, 29% Elastane | Style: Boxers
Why it’s great: Designed with the active lifestyle in mind, Lululemon’s version of men’s seamless underwear is ideal for working out, but will also make the daily commute considerably more comfortable. My favorite feature is the breathable mesh that’s strategically placed in the areas most prone to sweat.
How it feels: Think of a pair of cycling shorts and then turn up the softness to the kind of levels you’d expect from a silk blanket. Impressive, right?
Flaws but not dealbreakers: Like many brands, Lululemon insists underwear can only be returned if unused and still in its original packaging. Unless you want to be stuck with a pair of boxers that don’t fit, it’s important you get your size right.
Sizes Available: XS-XXL | Colors Available: 3 | Material: 60% Nylon, 32% Polyester, 8% Elastane | Style: Boxers

And did I mention supportive? Designed without unnecessary stitching and seams, they’re a must-have for every guy, regardless of shape or size.
How it feels: Slip these on and you won’t want to take them off. They’re as smooth as a seal and feel really premium. I’m putting these firmly in the ‘luxury’ category.
Flaws but not dealbreakers: They’re not cheap, but you can save money if you buy them in bulk. Buy any five pairs and you’ll save 10%, nine for 20%, and 13 or more for 30% off.
Sizes Available: XS-3XL | Colors Available: 10+ | Material: Cotton/Modal | Style: Boxer Briefs
Buying Considerations for Men’s Seamless Underwear
The first commandment of seamless comfort is to prioritize the right fabric. Generally speaking, the primary characteristic of seamless underwear for men often involves synthetic materials like nylon or microfiber. However, some manufacturers have started combining these with cotton to offer a unique fusion of softness and a smooth silhouette.
Seamless doesn’t mean one-size-fits-all. Pay attention to the design and fit of the underwear to ensure it compliments your body shape (and private parts). Look for options with a contoured pouch for added support and a snug fit without the risk of sagging or bunching. Whether you prefer a boxer brief, trunk, or brief style, the best men’s seamless underwear should feel like a second skin, providing a sleek and invisible profile under your clothing.
As with all types of underwear, seamless styles vary in price depending on the brand, materials used, and several other factors. You should expect to pay anything from $10 per pair to $40. However, paying more doesn’t always mean you’re getting the best. The price can be a good indication of quality, but you should focus more on the materials and construction.

A blend of synthetic materials such as nylon, polyester, and spandex is generally considered best practice. These fabrics are chosen for seamless underwear because of their stretchability, durability, and snugness. The synthetic blend ensures that the underwear molds to the body, reducing the chances of irritation or visible lines under clothing.
Men’s seamless underwear offers the unbeatable combination of comfort and style. It eliminates the irritation caused by traditional stitched seams, providing a smooth, second-skin feel. The absence of seams means no visible lines under clothing, making it an ideal choice for those who value a polished appearance.
