X4D Bikini in Navy Blue: Cut from a single piece of fabric for minimal seams
This avant-garde X4D men’s pouch bikini in navy blue 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 navy blue bikini 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 Bikini in Navy Blue 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.

I love the X4D in general due to an extremely comfortable pouch and general high quality of workmanship. This style has a finer fabric from the other styles which [at least in the navy and pink colors] which makes it even more comfortable. This style runs a bit small [I normally wear a medium in ergowear styles but the large fits better for me]. The only thing that I would change is the center seam in the pouch – I like a clean pouch feel and look. I know that ergowear has a seamless design in the Feel collection but that pouch is not at all comfortable for me [pushes the anatomy to the side instead of comfortably lifting forward].

I had ordered the X4 D Navy Bikini M (not L) but the size fits like an S. The same issue arose with the Smoke blue colour bikini. No wonder ergowear announced a store wide discount on these two :joy: Disappointing given that I've been a regular customer since 2017 and have purchased items worth hundreds of dollars.
