Between you and me, most guys overlook one simple garment that could seriously elevate their fitness game: their underwear. You know what’s funny? We obsess over gym shoes, workout shirts, and high-tech bottles—but when it comes to what to wear under gym shorts, underwear often gets treated like an afterthought.
Isn’t it weird that something literally worn on your skin, beneath everything else, has such a huge impact on how you feel, move, and perform — yet is dismissed as purely functional? Let’s dig into why the best athletic underwear for men isn’t just about support; it’s about mindset, confidence, and even preventing common workout nuisances like chafing.

The Psychology of Unseen Clothing: Enclothed Cognition
You’ve probably heard about enclothed cognition, right? It’s the psychological phenomenon where the clothes you wear influence your attitude and performance. Usually, people talk about sharp suits or power ties, but here’s the twist: it starts with your base layer.
Imagine slipping on a pair of compression shorts or quality athletic underwear before a workout. Even if no one sees it, your brain recognizes something different. The snug fit, the smooth fabric, the intentional design all send subtle signals—like a secret pep talk—that prime you to move better and feel more *ready.*
Companies like Erogenos understand this well. They craft underwear not just to hold you in place, but to foster a sense of empowerment through comfort and fit. Likewise, the School of Self Image, although primarily a personal development academy, emphasizes how clothing choices—even unseen ones—shape self-perception and confidence, proving it’s not just surface level.
Why It Matters Even if No One Sees Your Underwear
- Mindset Boost: Wearing something thoughtfully designed helps you feel more intentional and less sloppy.
- Physical Cue: The tightness or smoothness can serve as a bodily reminder to stand tall, engage your core, and prepare for action.
- Self-Care Ritual: Choosing the right underwear is a daily habit that promotes discipline and a little moment of self-respect.
Men’s Underwear: From Utility to Self-Expression
Let’s face it: for decades, men’s underwear has been boxed into one role—containing and supporting. But the modern landscape is different. Men’s underwear is now a tool for self-expression and performance, mirroring daily habits for self-confidence style sensibilities and personal values.
Ever notice how some athletic underwear blends sleek aesthetics with cutting-edge fabrics? That’s no accident. Performance underwear companies focus on breathability, moisture-wicking properties, and ergonomic design, which isn’t just for function—it’s for making you feel good.
For example, compression shorts benefits go beyond muscle support and blood flow. They reduce muscle fatigue by limiting vibration, but they can also make your silhouette look sharper under gym clothes, subtly boosting your confidence. And that confidence matters because there’s a psychological interplay at work. Feeling good right at the base layer creates an invisible armor of motivation.
Common Mistake: Treating Underwear Purely as Functional
Most men fall into the trap of choosing whatever is cheap, available, or “just comfortable.” But here’s what they miss:
Once you start seeing briefs, boxer briefs, or compression shorts for what they really are—a performance tool—you’ll approach your workout with a new level of intentionality.
Building Confidence from the Base Layer Up
Confidence isn’t just a feeling; it’s a state that feeds off physical sensations. Wearing the right underwear is like laying down the foundation for that feeling.
Think of it as the groundwork of a house. If your base is shaky—uncomfortable underwear, chafing, or constant adjusting—you won’t stand tall no matter how handsome your jacket or shoes are.
With the right choices, you create a subtle but constant reminder that you respect your body and your workout regimen. When you internalize that respect, it shows in your posture, your movements, and your endurance.

What to Look for in “Best Athletic Underwear for Men”
The Daily Ritual of Choosing Your Undergarments
Between the frenzy of mornings, it’s easy to rush through underwear selection like it’s a mental checklist item: clean pair, check. But what if choosing your base layer was a moment of mindfulness?
Ever notice how habitual choices shape your mood for the day? Establishing a moment to consider your underwear — *really consider* it — can instill a quiet sense of discipline, preparing you mentally for whatever challenge lies ahead.
A simple ritual: pick underwear that fits well, feels soft against your skin, and aligns with your workout plan. By doing this consistently, you’re training more than muscles—you’re training your brain to associate comfort and readiness with physical effort.
Bonus Tips to Prevent Chafing During Exercise
- Choose seamless or flat-seam underwear to minimize friction points.
- Look for fabrics with moisture-wicking properties to keep skin dry.
- Consider compression shorts as a base to hold everything snug without restriction.
- Use anti-chafing balms or powders if you’re prone to irritation in sensitive areas.
Brands like Erogenos are pioneering underwear designed to prevent the annoyances that ruin workouts before they start. Meanwhile, resources from School of Self Image help men rethink how they own their style—starting with what no one else sees.
Conclusion: Underwear Isn’t Just Underwear Anymore
So, can a good pair of underwear improve your workout? Absolutely. From boosting confidence through enclothed cognition to preventing chafing and improving physical performance, delicate details beneath your gym shorts matter. Your base layer is the foundation for your entire workout experience—ignore it at your own peril.
Next time you ask yourself, what to wear under gym shorts?, don’t settle. Think quality fabrics, ergonomic fits, and even the psychology behind your choice. Your body and mind will thank you.
Remember, style is more than a surface game. It’s a conversation between your environment, your attire, and your self-image—starting with socks and underwear, and working all the way outward. When you get this right, you’re not just dressing for the workout; you’re dressing for success.
