Best Underwear For Working Out: Comfort Without Chafing

Written by Bill M.Published on June 26, 2025

When it comes to crushing your workout, the last thing you want is to be distracted by uncomfortable underwear. Chafing, bunching, and sweat-soaked fabrics can turn a killer gym session into a miserable experience. That’s why choosing the right underwear for working out isn’t just a nice-to-have — it’s a game changer. At Shinesty, we’ve made it our mission to design underwear that keeps you feeling fresh, supported, and downright sexy, no matter how intense your sweat session gets. Say goodbye to irritation and hello to comfort that moves with you, not against you.

You Should Know

Before you dive into the world of workout underwear, here are the three most important facts you need to keep in mind:

  1. Fabric Matters: Breathable, moisture-wicking materials like micro-modal and performance blends are your best friends. They keep sweat at bay and prevent that sticky, uncomfortable feeling.
  2. Fit is King: Underwear that fits snugly without being restrictive stops chafing dead in its tracks. Look for designs with flat seams and stretchy fabrics that move with your body.
  3. Special Features Count: Pouches like our signature Ball Hammock® for men provide targeted support and separation, reducing friction and boosting comfort during any workout.

Why Fabric Choice Is Everything For Workout Underwear

Let’s get real: cotton might be comfy for lounging, but it’s a nightmare when you’re sweating buckets. It soaks up moisture and holds onto it, turning your underwear into a damp, chafing mess. That’s why we at Shinesty swear by micro-modal fabrics and high-tech blends that wick moisture away from your skin like a boss.

Micro-modal is silky soft, breathable, and lightweight — basically the superhero of workout underwear fabrics. It keeps you dry and cool, even when you’re pushing your limits. Plus, it’s naturally odor-resistant, so you can trust it to stay fresh through multiple wears.

We also incorporate spandex and polyester blends to add stretch and durability. This combo means your underwear won’t sag or lose shape after a few rounds of squats or sprints. Instead, it hugs your body in all the right places, giving you freedom of movement without any pinching or bunching.

Why Shinesty’s Ball Hammock® Pouch Is A Game Changer

Men, listen up: the Ball Hammock® pouch isn’t just a clever name. It’s a revolutionary design that cradles your boys in a way that traditional underwear simply can’t. By providing dedicated space and support, it prevents everything from getting smooshed together, which is a major cause of chafing and discomfort during workouts.

This pouch also helps with airflow, reducing sweat buildup and keeping you cooler down there. It’s like having a personal air conditioner for your nether regions. And because it’s built into our outrageously soft fabrics, you get all this tech without sacrificing style or comfort.

Finding The Perfect Fit: What To Look For

Fit isn’t just about size — it’s about how your underwear moves with you. Too tight, and you’re asking for chafing and restricted blood flow. Too loose, and you’re dealing with bunching and constant adjusting. At Shinesty, we nail the sweet spot with cuts designed to hug your body without squeezing it.

Look for underwear with flatlock seams that won’t dig into your skin or cause irritation. Seamless options are also fantastic for those who want zero distractions during their workout. Our women’s cheeky cuts and men’s briefs are designed with these features in mind, so you get maximum comfort and style.

Don’t forget about the waistband! A soft, wide waistband that stays put without pinching is crucial. Shinesty’s waistbands are made to flex and hold, so you can jump, run, and stretch without worrying about your underwear riding up or down.

Tips For Preventing Chafing During Workouts

Even the best underwear can’t do all the work if you’re not careful. Here are some pro tips to keep chafing at bay:

  • Keep your skin dry — use a sweat-wicking powder or anti-chafing balm if you’re prone to irritation.
  • Choose underwear with moisture-wicking fabrics like Shinesty’s micro-modal blends.
  • Make sure your underwear fits properly — no sagging or tight spots.
  • Wash your workout underwear regularly to prevent bacteria buildup that can cause irritation.
  • Consider seamless or flat-seam designs to minimize friction points.

What makes Shinesty’s micro-modal fabric better for workouts?

Our micro-modal fabric is ultra-soft, breathable, and moisture-wicking, which means it keeps you dry and comfortable even during the sweatiest workouts. Plus, it resists odors naturally, so you stay fresher longer.

How does the Ball Hammock® pouch improve comfort for men?

The Ball Hammock® pouch provides dedicated support and separation for your boys, reducing friction and chafing. It also enhances airflow, keeping you cooler and more comfortable during intense activity.

Absolutely! Our women’s underwear features cheeky cuts and performance fabrics designed to prevent chafing and provide all-day comfort, whether you’re hitting the gym or running errands.
