The Best Seamless Briefs to Wear Under Compression Gear (2025)

Put them on. Forget about them. Give your best.

When you’re in the middle of competing, working out at the gym, or just out and about and being active, the last thing you want to worry about is your underwear.

An uncomfortable pair will distract you.

A pair that chafes can be painful.

And of course there are other worries too: Is it showing? Am I on display? Any of this can throw you off and keep you from performing your best.

So, a great pair is definitely not something to take for granted and spending a little time to find what works for you can make all the difference.

Our top picks feature seamless briefs specifically designed for athletic performance.

This might go without saying, but there are definitely right and wrong underwear options when choosing a pair to wear under compression garments (leggings, bikers, volleyball shorts, etc.).

Whether you’re going for a personal best at the gym or giving your all in competition, you want to be in the zone and reacting freely, not distracted or restricted by an uncomfortable fit.

So, on this list you’ll find popular picks from leading activewear brands specifically designed for high performance and proven effective for many athletes across the board.

And since this list is focused on seamless briefs for layering under compression fabric, all the picks below have these two key features:

1. Soft and stretchy fabric blend geared toward performance.

What you’re looking for here is underwear that’s soft, lightweight, and breathable to keep you cool and comfortable while you’re active.

But you also need to pair these qualities with a stretchy fabric blend that’s durable, holds up against sweat, and allows a full range of motion.

2. No seams for an undetectable fit and friction-free layering.

These can go by a few different names and styles: laser-cut, raw-edge, seamless design, etc.

But what we’re talking about are seam-free designs (i.e. no visible panty lines) for a smooth fit and appearance under snug-fitting compression fabric.

A few additional factors to keep in mind:

Of course, we come in all shapes and sizes and for this reason it’s difficult to say with certainty which underwear style or design is going to work best for you.

Beyond the two key features above, look for other characteristics that match your wants and needs when active.

For example, some briefs may offer no-slip grip on the waistband for a more secure fit while others tout great stretch recovery for long-lasting garment integrity.

A good rule of thumb for athletes: You’ll know you’ve found the right pair when you’re not giving them a second thought.
