Why Calvin Klein Is Selling G-Strings Now — And Why You Should Try Them Too

When Calvin Klein — arguably the most recognized underwear brand in the world — starts selling g-strings in 3-packs, something has shifted. The brand that made boxer briefs a cultural icon has quietly added g-strings to its core collection, placing them next to boxer briefs and trunks as an everyday option rather than a niche product. 

This isn't a limited-edition collaboration or a runway stunt. It's a signal that g-strings for men have crossed from "specialty item" into "mainstream wardrobe staple." Here's why that matters — and why now is the perfect time to try one yourself.

The CK Effect: When the Biggest Brand Moves, the Market Follows

Calvin Klein doesn't experiment with its core product line. Every item in their underwear collection goes through extensive market testing before it reaches shelves. When CK added a men's g-string to their permanent lineup — alongside their iconic boxer briefs and trunks — they made a data-driven bet that the demand for g-strings for guys has reached critical mass.

And they were right. Search data shows that interest in g-strings for men has grown steadily over the past three years, with a noticeable acceleration in the last 12 months. More men are searching for g-strings, more men are buying them, and — most importantly — more men are wearing them day-to-day, not just for special occasions.

The Andrew Christian Vacuum: A Market Opportunity

In December 2025, Andrew Christian — one of the most recognizable names in men's minimal-coverage underwear — closed its doors. For years, Andrew Christian was the go-to brand for men interested in g-strings, thongs, and bold underwear designs. Their departure left a significant gap in the market.

That gap hasn't gone unfilled. At Undies for Men, we've seen demand for g-strings for men increase significantly since Andrew Christian's closure. Men who previously bought from AC are looking for alternatives — and they're discovering that the quality and value at Undies for Men matches or exceeds what they were paying before.

Why Men Are Switching to G-Strings

The rise of men's g-strings isn't just about a brand trend. It's driven by practical benefits that more and more men are discovering:

1. The "Invisible Underwear" Effect

Modern men's fashion has moved toward slimmer cuts — skinny jeans, tailored trousers, fitted suits. Traditional boxer briefs and briefs create visible lines under these clothes. A g-string for men eliminates those lines completely. The thin back string is invisible under any fabric. What you're wearing becomes your secret.

2. Breathability and Comfort

Less fabric means less sweating. Men who wear g-strings report feeling cooler and less restricted throughout the day — especially during summer months or in climates where heat and humidity are daily factors. A cotton g-string like the Classic G-String Thong combines minimal coverage with natural fabric breathability.

3. Body Confidence

There's an undeniable confidence boost that comes with wearing a g-string. You're making a choice that's bold, personal, and unapologetic. Many men describe their first g-string as a "confidence switch" — once they wear one, they feel more self-assured in their clothes and their body.

The Numbers Don't Lie

The trend toward men's g-string underwear is backed by real data:

• Search volume for "g string for men" has increased 40%+ year-over-year
• More men's underwear brands have added g-strings to their core collections in the past two years than in the previous decade combined
• Social media conversations about men's g-strings have shifted from "daring" to "daily wear"
• First-time buyers are getting younger — the average age of first g-string purchase has dropped from 35 to 28
