When was the last time you upgraded your underwear? It's a personal question, I know. And one that most guys don't think about very often. A lot of men end up picking their underwear type during their adolescence and just sticking with it—out of convenience, familiarity or laziness. But have you ever considered that there could be something better out there? Something that suits your needs, provides ultimate comfort and maybe even helps you look better in your clothes?

I'm talking about seamless underwear, which is exactly what it sounds like. It's underwear with little to no seams. What's the benefit to cutting out all that stitching? Well, for starters, it's a whole lot more comfortable. Nothing rubbing up against your junk or seams riding up or twisting when you sit down. Plus, there are no protruding stitching, which can cause visible lines in your pants. And since these modern boxers are often made from athletic-infused fabrics, they're stretchier, more supportive and are much better at retaining their shape without stretching and sagging over time. Plus, these enhanced fabrics tend to absorb less sweat and wick away moisture better than your standard underwear. That means you feel (and smell) a whole lot fresher throughout the day and night.

Simply put, switching to seamless underwear gives you all the freedom and ease of going commando, with added support.
