Featured Review: ( Of 29 Reviews )

Size : M
These are so comfortable that I just bought another half dozen. Super soft cotton. The band up front rides just above the pubic bone which feels awesome. The pouch is key, contains but does not compress, still allows the lads to extend away from the body. Will probably fit best for guy parts towards the top of the bell curve. I’m a couple sizes above 32, still use a medium, because I have a smaller butt.

About C-in2

C-in2

C-in2 men’s underwear delivers quality, fit and trend-setting style that are pure and simple. C-in2 offers a large selection of briefs, boxers, boxer briefs, t-shirts, and athletic wear for men of all ages. Some popular C-in2 items include the Sling Support Lo No Show Profile Brief and the Profile Boxer Brief. C-in2 is poised to become the industry leader in innovation.

A relatively new brand to the market, C-IN2 was launched in 2005 by Gregory Sovell, one of the founders of 2(x)ist. It didn't take long for C-IN2 to become widely known and very popular. The C-IN2 line includes briefs and trunks, designed with a low-rise cut and contour-enhancing pouches. The brand also offers lean-cut tanks, and tees inn both a classic and slim cut. C-IN2 uses fabrics that feel ultra-soft against the skin, including 100% cotton, a high-tech modal material and cotton/modal blends. Customers rave about the softness of the fabrics.

C-In2 also features bold colors, along with basic black and white. Expect to find styles in neon yellow, bright red, navy, chocolate, citrus green and more. The brand also offers eye-popping stripes in briefs and trunks.

It didn't take long for men to find this exciting new brand. With Sovell as Creative Director, we can expect to see a continuing trend of exciting designs, high-quality workmanship and innovative uses of modern fabrics.
