Our take on the Ergowear EW1766 X4D SW Swim Briefs

The Ergowear EW1766 X4D SW is a men's swim brief built around Ergowear's X4D ergonomic pouch, which lifts and separates for support instead of pressing everything flat. It is a polyester brief with a drawstring waist, sold in S, L and XL. At $36.95 at eBay as of November 4, 2026, it is the lowest of the four stores listing it new, and that price sits at the bottom of its recent range rather than above it.

Best forMen who want pouch support in a swim briefLap swimmers who prefer a low-drag cutBuyers replacing a worn competition-style briefGym and pool users who want a drawstring waist
Pros
  • X4D pouch gives lift and separation rather than compression
  • Drawstring waist holds the brief in place off the blocks and in surf
  • Polyester dries fast and resists chlorine better than cotton blends
  • Low-cut brief shape means less drag than trunks
  • $36.95 at eBay as of November 4, 2026 is the cheapest of four new listings
Cons
  • Brief cut is not for everyone; many men prefer trunks or jammers
  • Only S, L and XL listed, so M and larger sizes may be hard to find
  • Polyester has less stretch than the nylon-lycra most swim briefs use
  • Limited color and pattern choice compared with big swim brands
  • Pouch design adds seams that some wearers find noticeable

Questions and answers

Is the Ergowear X4D SW brief worth $36.95?
If you want pouch support in a swim brief, yes. At $36.95 at eBay as of November 4, 2026 it is the lowest of the four new listings, and plain competition briefs from big brands often cost less but offer no pouch.
How does the X4D pouch compare with a standard swim brief?
A standard brief presses the front flat against the body. The X4D pouch is cut with extra room and seams that lift and separate, which most owners find more comfortable for long pool sessions.
What size should I order?
Ergowear lists S, L and XL here, and owners often report the fit runs small. If you are between sizes, take the larger one, and check the store's size chart since the cut is regular, not relaxed.
Does the drawstring waist stay tied in the water?
Yes. The drawstring lets you cinch the waist so the brief stays put during dives, turns and surf. Tie it before swimming rather than relying on the elastic alone.
Is polyester good for chlorinated pools?
Polyester resists chlorine and dries quickly, which suits regular pool use. It has less stretch than nylon-lycra, so the fit feels firmer and the brief may not hug quite as closely as elastane blends.
When is the price lowest?
Swimwear usually discounts at the end of summer and around clearance events. The current $36.95 at eBay as of November 4, 2026 is already the lowest of four new listings, so waiting may not save much.
Where is the Ergowear EW1766 X4D SW Swim Briefs cheapest?
At eBay, for $36.95, as of our latest check.
Where can I buy the Ergowear EW1766 X4D SW Swim Briefs?
11 stores we checked sell it, including eBay, Freshpair, MensUnderwearStore.com, SexyMenUnderwear.com, Byron's Britches.
