If you thought the world of men’s underwear peaked when someone invented tighty whities, think again. In 2025, men are becoming more particular in choosing underwear, and there are trends to show for it.
Gone are the days when men grabbed whatever undies on sale at the supermarket. Today, new undergarments are making headlines, appearing on TikTok, and even influencing dating success (don’t quote us, but we’re 94% sure).
Men everywhere are demanding comfort, style, sustainability, and serious support while walking, running, or going about their day. Welcome to the big league of men's underwear trends. Let’s take a tour.
Trend 1: Everyday Comfort and Performance
Fabrics Matter
Still wearing undies that feel uncomfortable? In 2025, we see comfort reigns supreme, and today's underwear styles lean towards ones suited for everyday wear. Think cotton boxers with moisture-wicking fabric, or a snug-fit bamboo underwear.
While bamboo and cotton are strong, smooth, breathable, and undeniably iconic, there has also been a rise in modern synthetic fabrics. For example, SWAG's men's underwear range is made from Micropolyester/Elastane with Bamboo lining, making it incredibly breathable and sweat-wicking
Athletic-Inspired Styles
Athleisure has escaped the gym and infiltrated underwear drawers worldwide. Boxer briefs and trunks that are breathable have become the go-to for modern men. Performance underwear has solid support and stretches during physical activities.
Support and Comfort
Men's underwear has always prioritised maximum comfort and ample support, but we see these trends becoming more important than ever. Today's underwear helps men in their testicular health (hello, good sperm count!), has good leg coverage (even with form-fitting clothes), and is on a personal mission to prevent chafing.
Trend 2: Personal Style + Expression
Bold Colours + Patterns
Still wearing boring black-and-grey underwear? Those days are over. Bring on the beer undies, footy undies, stripes, zigzags, polka dots, and edgy prints that say, “Yes, this is my personality.”
Underwear styles, just like most trends in men's fashion, have shifted towards being fun and expressive. Men's underwear these days is a reflection of their individuality and personal preferences.
Visible Waistbands
Underwear isn’t just underwear anymore—it’s an accessory. Whether it's loose boxers or tight briefs, visible lines of waistbands with bold branding are popping up everywhere - peeking out of slim-fitting pants, loungewear, and gym shorts.
Trend 3: Sustainability
Eco-Friendly Materials
Eco-friendly fashion has made its way to many men's underwear brands, and most men now expect their underwear to be good for the planet and good for their skin.
Organic cotton, bamboo blends, and recycled fibres are all firmly at the front of the sustainability movement. These fabrics don’t just feel great; they carry far less environmental guilt than traditional options.
SWAG Boxers are ethically manufactured with transparent supply chains, low-waste manufacturing, and proper labour practices. These are non-negotiables as we create quality underwear.
Trend 4: Body-Type Specific Underwear
One of the most interesting trends is the shift toward body-type designs. Underwear brands are finally realising what men have known forever: not all bodies are built the same, and men's undies really shouldn’t be either.
Today’s designers are creating underwear made for different shapes, builds, and proportions:
- For larger thighs: Stretchy trunks or boxer briefs with anti-chafe are becoming hugely popular.
- For leaner frames: Shorter inseams and bigger pouches help create better comfort and a balanced look.
- For athletic builds: Performance fabrics with supportive waistbands that keep everything in check
-
For bigger bellies: Higher-rise waistbands that stay put are trending across comfort-focused brands.
- For longer legs: Longer inseam boxer briefs prevent ride-up and avoid the “underwear turning into hot pants” effect.
- For shorter legs: Trunks with a shorter cut create a more proportionate wear.
Underwear Styles Dominating 2025
1. Trunk Underwear
Trunks are like boxer briefs’ cooler, trendier, younger brother who travels, wears cologne you can’t pronounce, and knows how to make a mojito. They’re shorter, modern, and universally flattering. Perfect for men with shorter leg lengths who want something supportive but stylish.
2. Boxer Briefs
Still the reigning champion in global underwear sales, boxer briefs balance comfort, coverage, and performance. They work for men with bigger thighs in every situation, from office jobs to gym sessions. If it's not broken, why fix it?
3. Briefs
Men's briefs are making a huge comeback—especially with Gen Z, who have declared them “bussin” Briefs provide maximum support with minimal fabric. They are practical, airy, and surprisingly stylish, essentially perfect for all body types.
