The Best Seamless Thongs 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.

Spending a little time and effort to find what works for you can make all the difference.

Here, we’ve picked out seamless thong options that work great under compression gear, whether it’s your leggings, yoga pants, compression tights, compression shorts, and more.

What Underwear Is Best for Under Leggings and Tights?

Well, for starters, it’s worth mentioning that some women prefer to go without underwear beneath their leggings, tights, and compression gear, which is totally fine.

In fact, compression wear is intended to be worn as a base layer (i.e. worn right against the skin), so adding a layer of fabric between your compression and skin, even underwear, can slightly hinder the benefits of compression.

However, there are many women that prefer to wear underwear beneath their compression garments.

The reasons for doing so usually revolve around matters of comfort—an important factor in athletic performance that should never be overlooked.

With that in mind, there are definitely certain underwear options better suited to wear under compression gear than others.

Here, we’ve highlighted seamless thong options designed for activity that work great under your running tights, workout leggings, volleyball shorts, soccer shorts, and much more.

Criteria for Our Top Seamless Thong Picks

1. Comfort. Underwear that fits and feels comfortable under snug-fitting compression garments. We’re looking for a seamless design and material that’s soft, durable, and lightweight.

2. Functionality. Underwear that’s functional during activity. We want it to stay in place, have performance-minded features, and not require a second thought.

3. Appearance. Underwear that you don’t ever see. We’re talking no visible panty lines here (no VPL). One less thing to worry about will help keep you focused.

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.

There’s always going to be some trial and error involved.

But we gathered these picks based on what met our criteria and worked well for many women across the board.

And we’re confident you’ll find a seamless thong on this list that fits just right and becomes your new favorite.
