Customer Reviews
Good deal on quality items
I was looking for some new boxer briefs and saw C-IN2 had a clearance sale. I picked up a few pairs of their Throwback Boxer Briefs at a really good price. I always try to get the most for my money, and these were definitely a solid find. They're comfortable and seem well-made. The value for what I paid was excellent, especially with the discount. Shipping was reasonable. I'd definitely check out their sales again for good deals.
Love the fit and feel!
I got the Profile Boxer Briefs and they are amazing! The fit is just perfect and the fabric is super soft. I've never had underwear that felt this good. The delivery was quick too. I'm definitely going to buy more of these, maybe try some of their other styles next time. So glad I found this brand!
Happy with my first order
I needed some new athletic supporters and decided to try C-IN2. I got two of their Performance Jocks. The ordering process was straightforward on their website, no issues there. Shipping was pretty standard, it arrived in about a week. I had a question about sizing before I bought, so I used their contact form and got a helpful response within 24 hours. The jocks themselves are well-made and very comfortable for workouts. The material feels durable. I'm definitely considering another purchase, maybe a few more of these or some of their boxer briefs next time.
Decent underwear, delivery was okay
I ordered some Zen Briefs during their last sale. The underwear itself feels really good, very soft material. They fit as expected, which is always a plus for online clothing. My order took 5 days to reach Denver, which isn't terrible but not super speedy either. I wished they had better tracking updates, it was a bit vague for a day or two. Good value overall for the price I paid.
Comfortable jockstrap
Got a Core Jockstrap. Fits great. Material is soft. Shipping was fast. Would buy again.
Good quality, quick shipping
I grabbed a few Core Boxer Briefs from C-IN2 a couple weeks ago. They came pretty fast, like 4 days to get to my place in California. They fit well and are comfy, so I'm happy with them. Nothing bad to say really, just a solid purchase.

Share tips, ask questions & help fellow shoppers save more
Hey, I'm looking at getting some of the Zen briefs. How do these compare to the Core line? Like, what's the actual difference?
Are their jockstraps generally true to size? I'm usually a medium, but sometimes brands run small.
Just wondering about shipping times to LA. Need a few jockstraps for a party next weekend. Will they make it?
can you combine discount codes on this site? trying to use a first-time discount and a free shipping one.
