Fair overall quality but room for improvement with regards to quality inspection and design. One of the mens classic briefs i purchased online has defective stitching which is easily noticeable and it will probably unravel if I start wearing it.
And then speaking from experience... the waist band of the Jockey Tangas tends to unravel a bit and stretch out where the two ends of the band is stitched together and it's usually located on the side of the hip as opposed to the regular backside joint with label stiched over for improved strength and durability. The letters from the word JOCKEY on the waist band in the area of the joint is also stretched wide compared to the rest of the letters on the waist band.
