Should You Wear Underwear With Compression Pants?

Written by Bill M.Published on July 10, 2025

Alright, let’s cut to the chase: compression pants are the unsung heroes of your workout wardrobe. They hug your muscles, boost circulation, and keep you feeling like a superhero in spandex. But here’s the million-dollar question that’s been bugging everyone from gym rats to casual joggers — should you wear underwear underneath these bad boys? We’re diving deep into this sweaty, stretchy debate to give you the lowdown, Shinesty style. Spoiler alert: it’s not just about comfort; it’s about performance, hygiene, and yes, your dignity.

You Should Know

Before you decide whether to go commando or suit up with your favorite pair of briefs, here are the three most important facts you need to keep in mind:

  1. Compression pants often come with built-in liners or antimicrobial fabrics that reduce the need for underwear, but not all are created equal. Knowing your gear is key.
  2. Wearing underwear can sometimes cause extra friction and moisture buildup, leading to chafing and discomfort — the exact opposite of what compression pants are supposed to do.
  3. Choosing the right underwear fabric and fit is crucial if you decide to wear them under compression pants. Shinesty’s MicroModal fabrics and seamless designs are game-changers here.

Why Wearing Underwear With Compression Pants Is a Personal Choice

Let’s get real: whether or not to wear underwear under compression pants is a personal call, but it’s one that deserves some serious thought. Compression pants are designed to be tight and supportive, often made from moisture-wicking, breathable materials that keep you dry and comfy during your sweatiest sessions. Because of this, many people find that going underwear-free actually enhances the benefits of compression wear.

However, not all compression pants are created equal. Some come with a built-in liner that acts like underwear, providing a barrier between your skin and the fabric. If your compression pants have this feature, you might not need anything else underneath. But if they don’t, wearing underwear can add an extra layer of protection, especially if you’re prone to irritation or want a little more coverage.

Here’s the catch: wearing regular cotton underwear under compression pants can trap moisture and cause friction, which leads to chafing — the enemy of every athlete and casual mover alike. That’s why we at Shinesty recommend our MicroModal underwear, which is silky soft, breathable, and designed to keep you dry and chafe-free. Plus, our seamless construction means no annoying lines or bunching under your compression gear.

Built-In Liners: Yay or Nay?

Compression pants with built-in liners are like having your cake and eating it too. They provide the support and moisture control you need without the bulk of extra underwear. But not all liners are created equal — some are thin and breathable, while others can feel restrictive or less hygienic if not washed properly.

If you’re rocking compression pants with a liner, you might want to skip underwear altogether. Just make sure to wash them regularly and choose pants made from antimicrobial fabrics to keep funk at bay.

Fabric Matters: Why Shinesty’s MicroModal Underwear Rocks

When you do decide to wear underwear under compression pants, fabric choice is everything. Cotton? Meh. It soaks up sweat and stays wet, turning your workout into a swamp fest. Synthetic fabrics? They can trap heat and cause irritation.

Enter Shinesty’s MicroModal underwear — the silky, breathable, moisture-wicking miracle your nether regions have been begging for. Our MicroModal fabric is softer than a cloud, dries fast, and fights odor like a champ. Plus, our no-VPL seamless panties and Ball Hammock® pouch underwear are engineered to eliminate friction and keep everything in place, so you can focus on crushing your workout instead of adjusting your gear.

How to Rock Compression Pants With or Without Underwear

Whether you’re team underwear or team commando, here’s how to make the most of your compression pants experience:

  1. Choose the right fit: Compression pants should be snug but not painfully tight. Too tight, and you risk cutting off circulation; too loose, and you lose the benefits.
  2. Pick the right underwear: If you wear underwear, go for breathable, moisture-wicking, and seamless options like those from Shinesty. Avoid cotton and bulky seams.
  3. Keep it clean: Wash your compression pants and underwear after every use to prevent bacteria buildup and funk.
  4. Listen to your body: If you notice chafing, irritation, or discomfort, switch up your underwear or try going without it for a session.
  5. Consider the activity: For high-intensity workouts or long runs, moisture control is king. For casual wear or yoga, comfort might take priority.

Tips for Preventing Chafing and Discomfort

Chafing is the ultimate buzzkill, but it’s totally avoidable with the right gear and habits. Here’s how to keep your skin happy:

  • Use Shinesty’s moisture-wicking underwear to keep sweat at bay.
  • Apply anti-chafing balms or powders to hotspots before workouts.
  • Make sure your compression pants fit properly — no sagging or pinching.
  • Switch up your underwear regularly to avoid bacteria buildup.
  • Opt for seamless designs to eliminate friction points.
