"I recently bought a few pairs of Calvin Kline briefs, cheaper than Ergowear which have been favourites for years. Have to say there not a patch on any EW product, amazes me that such a popular brand is so uncomfortable, pull EW pants on junk drops into the pouch with no crushing just gentle aground support, lovely!"

"I have purchased several of Ergowear styles from DGU- thongs, bikini briefs and mid briefs. They all very comfortable and well made. However, I find the sizing runs small. I take a size L in Hom and Olaf Benz and a size M in Impetus, but i really need a size XL in Ergowear. These XD 4 briefs are extremely comfortable and i will be purchasing more. The colours and fit are great! "

"Just received my first pair of X4D pants, bought on Black Friday at a good discount. Slightly fuller cut than X3D, so not as skimpy. Very comfortable to wear, as always plenty of space and support for your tackle, pink is a nice subtle colour . Love Ergowear, these pants look great, create a nice bulge, perfect support and quality which justify’s the price "

"Yet again, the most comfortable pants I have ever worn."
