Greatest Underwear

You won’t be disappointed with any of the products from C-IN2…. I only wear two brands and C-IN2 is top notch for those looking for style (looking their best) and comfort!

Been buying from you guys going on 10 years

Only company I will go for when it comes to purchasing underwear. I've tried other companies and the comfort and fit of the products are uncomparable. These are awesome and will be buying more!

Great Underwear.

I love these. They wear like iron. Have been wearing these many years. Just wish the pouch was a bit bigger. I had the Core series several pairs ago and the pouch seemed to have shrinked a bit over the years.

Perfect pair

Good material. The underwear fit me perfectly. It feels so soft and comfy! The inner adjustable cockring is such an enhancement feature for adding an extra bulging, eye grabbing attention.
