X4D Thong in Black: Cut from a single piece of fabric for minimal seams
This avant-garde X4D men’s pouch thong in black is the upgraded version of our previous best-selling X3D underwear designs: Now cut from a single piece of fabric and sewn together only in the pouch using flat-seam technology. Although similar in appearance to its predecessor, the new design of the black thong fits on your body like a glove and represents a technological achievement that makes us proud. But wait, there’s more to these pouch boxer designs….
X4D enhancing pouch
The X4D Thong in Black features our most advanced pouch design yet. It looks like other pouch underwear you may have tried, but it has various details that will make a huge difference. With a nose shape to hold your anatomy pointing downwards while enhancing its shape and size, it also separates your testicles from your thighs. This results in 3-dimensional support with the added benefit of unmatched comfort, the 4th dimension that makes this pouch design even more special.
You can wear it all year in any climate. However, for colder climates, we recommend styles with more coverage, such as mini boxers or midcuts.
Be sure to check out both our underwear and swimwear collections featuring this groundbreaking X4D pouch design.
4-way elastic microfiber
Thanks to the ultra-soft polyamide-elastane microfiber, which is soft, fast-drying and highly elastic, you enjoy full freedom of movement.
Concealed supporting waistband
The concealed but strong waistband allows easy access, while perfectly supporting the weight of your genitals. It is a myth that narrow waistbands will slide down – at least ours don’t.

X4D Thongs have been a staple for me. These new ones have upgraded elastic that is covered in both sides making it even softer and nicer to wear. Highly recommend!

There have been some nice tweaks to the X4D in this re-release of the black variant. There's a slight semblance of a waistband, maybe a centimeter or slightly less of elastic, so it's slightly more structured than any of the X4D variants before. This alone has been tempting me to grab another two pair, but I've already got six or so black X4D or X3Ds.

LOVE LOVE LOVE this thong. Amazing fit. So comfortable. Perfect for sports or all day wear. Great quality. Durable. Super sexy. Looks good. Feels good. I've tried all sorts of brands and cuts. Nothing comes close to the designs and products from Ergo Wear. I wont buy my thongs from anyone else.
