5 Mens Underwear Styles Growing in Popularity Fast

Trunks are winning the mens underwear aisle. Here are the five styles driving the shift, the fabrics behind them, and how to pick the right one for daily wear.

Quick Summary

  • Demand for mens underwear is shifting fast, and mens trunks are leading the change as men move away from traditional briefs.
  • Fabric-forward styles — micro-modal and bamboo trunks for men — are the fastest-growing picks among online shoppers this year.
  • Boxer briefs and no-show trunk fits are gaining ground for their gym-to-daily versatility.
  • Freecultr's trunk collections are built around exactly these five rising style categories, in breathable, skin-friendly fabrics.

The Mens Underwear Aisle Is Changing Fast

If the last pack of underwear you bought was a generic three-pack of briefs, you're not alone — and you're also behind the curve. The mens underwear category has quietly become one of the more dynamic parts of a man's wardrobe, with new fits, fabrics, and silhouettes replacing the "buy what my dad wore" default.

Search and sales trends across Indian D2C innerwear brands point to a clear pattern: men are trading coverage-only basics for styles that balance comfort, support, and a cleaner fit under everyday clothing. Five styles in particular are pulling ahead of the pack, and understanding why can save you from buying the wrong pack again.

Classic Trunks: The Style Leading the Shift

Classic trunks are the single fastest-growing style in mens underwear right now because they solve the one thing briefs and boxers each get half-right.

Trunks combine the secure, no-ride-up coverage of briefs with the longer leg and squared-off cut of boxers, so they sit flat under jeans, joggers, and formal trousers alike. That "just enough coverage, just enough freedom" balance is exactly why mens trunks have become the default recommendation for men buying underwear for the first time in years, rather than restocking the same old style out of habit.

Micro-Modal Trunks: Why Comfort Fabric Is Winning

Micro-modal trunks are gaining share because the fabric itself outperforms standard cotton on the two things that matter most in daily wear: softness and moisture handling.

Micro-modal is spun from beech tree fibers into a yarn that's finer than regular cotton, which gives it a noticeably smoother hand-feel and better shape retention wash after wash. For men in hot, humid climates, that translates to less chafing and less midday discomfort — which is a big part of why fabric, not just cut, is now driving repeat purchases.

Fabric Feel Best For
Standard Cotton Breathable, slightly coarser Everyday budget wear
Micro-Modal Silky-smooth, stretch-retentive All-day comfort, sensitive skin
Bamboo Ultra-soft, naturally cooling Humid climates, odor control

Boxer Briefs: Bridging Gym and Daily Wear

Boxer briefs are growing because they're doing double duty — men are increasingly buying one style that works for both a gym session and a full workday, rather than separate drawers for "activewear underwear" and "regular underwear."

The longer leg gives extra coverage during movement, while modern stretch fabric blends keep the fit close enough to wear under fitted clothing without visible lines. For men who want fewer categories to shop for, boxer briefs are becoming the practical middle ground.

Bamboo Trunks: The Sustainable Style Gaining Ground

Bamboo trunks are trending for a mix of reasons that go beyond sustainability marketing — the fabric is naturally moisture-wicking and has inherent breathability that suits India's warmer, more humid months.

Men who've struggled with sweat-related discomfort in synthetic or heavier cotton blends are increasingly switching to bamboo-based trunks for the cooling effect alone, with the lower environmental footprint as a welcome bonus rather than the primary driver.

No-Show Trunks for Men: The Low-Profile Fit Trend

No-show trunks for men are rising because they solve a very specific, very common complaint: visible underwear lines under fitted trousers, joggers, or thin summer fabrics.

These trunks use a lower-rise waistband and a closer, second-skin fit designed to disappear under clothing rather than announce themselves. As more men wear slimmer-fit bottoms day to day, this near-invisible fit has gone from a niche preference to one of the most requested styles in the category.

Step-by-Step Guide to Choosing the Right Mens Underwear Style

Step 1: Identify your primary use case — daily office wear, gym and workouts, travel, or a mix of all three — since that narrows down cut and fabric fast.

Step 2: Decide on coverage and length. If you've never worn trunks before, start with a classic trunk length as your baseline before trying boxer briefs or no-show cuts.

Step 3: Pick a fabric that matches your climate and skin sensitivity — cotton for everyday budget wear, micro-modal or bamboo if comfort and breathability matter more.

Step 4: Check the waistband. A wider, soft-elastic waistband holds better through the day without digging in, especially for longer wear.

Step 5: Buy one trunk style first before committing to a full wardrobe switch, wear it through a full day, and use that as your benchmark for future packs.
