The Most Comfortable Thongs for Men 2025

Underwear’s most highly sought-after characteristic: Comfort.

This installment in our Most Comfortable Underwear Series is all about the most comfortable thongs for men.

And when we use the term comfortable, you might be wondering what level of comfort we’re actually talking about here.

To make our Most Comfortable List, we’re talking about underwear that fits like a second skin.

Underwear that you’re actually happy to put on and then forget you’re even wearing levels of comfort.

Now, of course, we know that men come in all different shapes and sizes, not to mention have different preferences when it comes to support, fabric type, etc.

For this reason, it’s difficult to promise that each thong listed here is going to fit and feel perfect to you.

So, while there may be some scrolling and a little trial and error involved, we’re confident that you’ll find an incredibly comfortable thong on this list that fits you just right and becomes your new favorite.

Go ahead, grab one or a few, and step into your most comfortable thong.

And for even more great options, check out the best thongs available on Amazon.

How We Make Our Picks for Most Comfortable Thongs

Look, we get it. Determining what makes a great pair of underwear can be a pretty subjective thing.

So, how do we decide which thongs make our list for the most comfortable? 

We tested a wide range of underwear brands and put them through the rigors of daily life and active situations.

And, as a result, we can say for certain that 3 specific qualities make for an objectively more comfortable underwear experience.

Reviewing thongs from leading men's underwear brands.

1. Premium fabric blends that support active bodies.

Your body moves in a wide range of motion throughout the day, and it doesn’t take much for it to overheat or experience distracting irritation.

We prioritized options with naturally soft and breathable fabrics that add a touch of stretch (spandex, elastane, etc.).

We’ve also found that while you may end up paying a little more for premium fabric, it tends to stay in better shape for longer.

2. Comfortable waistbands that stay in place. 

It’s not enough to just have a comfy waistband, and it’s not enough to have a waistband that’s only focused on staying put.

Comfort and function need to work hand in hand here.

We went with thongs that paid extra attention to this crucial detail.

3. Ergonomic features that prioritize the male anatomy.

It’s crazy how many men’s underwear options don’t seem to properly consider the male anatomy in their design.

After all, you’re not a retail display mannequin yet some brands seem to design their underwear that way.

Thongs that pay attention to the human body tend to layer better under clothing, cut down on adjustments and bunching, and help you forget it’s even there.

Here, you can see us testing one of our top picks, the Intymen Sensual Thong, which features all three of these key qualities. 

1. Fabric: Silky soft polyamide fabric with added spandex for comfortable stretch.

2. Waistband: An incorporated design that’s soft, wide, and stays put.

What to Look for When Purchasing a Thong

If you’ve spent any time shopping for thongs these days, you’ve likely noticed that there’s no shortage of options available to you.

In fact, there’s a wide variety of fabric choices, garment features, specialty designs, and more.

This should come as no surprise, as lots of men have begun adding thongs to their underwear drawer lately thanks to the many benefits.

But if you’re a bit overwhelmed by all the options and not sure where to start, here are a few characteristics that high-quality underwear brands tend to focus on.

A great thong will pay special attention to design and construction.

Fabric is key here, so prioritize options with soft and lightweight fabric blends that are naturally breathable.

It’s also a great idea to find a thong that mixes some stretch (nylon, elastane, spandex, etc.) into its construction for a non-constricting full range of movement, as well as a waistband that won’t roll or pinch.

Even though thongs provide a much freer fit than more traditional underwear options, lots of guys prefer that their thong provide pouch support.

If you’re one of these guys, go for options that mention targeted support and stretchy fabric blends.

These features tend to make for a great blend of comfort, support, and durability that’s perfect for all-day wear and will last a long time.
