The C-IN2 Core collection brings you 100% combed cotton basic underwear in white, black and heather grey. If you’re looking for everyday underwear, the C-IN2 Core briefs, thong, jockstrap, boxer, long john, and trunk are the most reliable, comfortable products on the market.

By crafting our underwear with 100% combed cotton, we ensure that you will be comfortable all day long. Unlike other companies for which “basics” implies “lower quality,” C-IN2 Core basics match the high standard of design and construction we guarantee with each pair of underwear.

The microfiber waistband keeps your underwear in place while subtly showing off the C-IN2 logo – a recognized promise of quality and style. Easy to wear and simple to care for, this is underwear for the busy man who prefers classic style.

All C-IN2 Core shirts are made in 100% pima cotton. Perfect on their own or under a button down, the C-IN2 Core crew neck, v-neck, and tank top are your ultimate go-to shirts. Unique with its non-torque design, your tee will always keep its shape, not twisting to one side after a few wears. Layer it, wear it on its own, and love its soft, luxurious feel every day.

Highly rated by customers, the C-IN2 Core collection is a fan favorite. Men who care about their undergarments choose these garments because they are the best fitting everyday basics around. No matter where you’re going, how you dress, or what you enjoy, this collection will never let you down. Try a pair of underwear or a shirt from the C-IN2 Core collection, and see if you don’t become a convert.
