Nylon can be found in everything from toothbrush bristles to phone lines, not to mention boxer briefs! This silky synthetic fabric is often used by underwear manufacturers to produce some of the softest boxer briefs they offer. Calvin Klein’s popular Steel collection wouldn’t be popular without it! It is almost always found in any microfiber blend fabric on the market. Its ability to expand and contract makes it an ideal fabric option for boxer briefs. In addition to the incredible lightweight softness it’s also surprisingly durable and doesn’t exhibit after multiple washes. Chances are you’ve already worn something with nylon in it, and now that you know why you liked those boxer briefs so much you can find more favorites here at HisRoom!
