Customer Reviews
Good quality, minor shipping issue
I bought a few pairs of the Core Boxer Briefs during their anniversary sale. The quality is really solid, they feel durable and fit well. Shipping took about 8 days to get to me in Florida, which was a bit longer than I hoped. Customer service was responsive when I asked about the delay though.
Excellent Zen Briefs, fast delivery
I ordered the Zen Briefs last week and they arrived super fast, in just 3 days! The fabric is incredibly soft and the fit is perfect. I was looking for something really comfortable for everyday wear and these definitely delivered. I'm so happy with this purchase, I'll definitely be back for more soon!
Punt Briefs purchase experience
I decided to try out the Punt Briefs based on some online reviews. The ordering process was straightforward on their website. I got a confirmation email right away. Shipping said 5-7 business days, and it actually arrived on the 6th day, so that was accurate. The briefs themselves are pretty good; the material is breathable and the pouch design is supportive. I did notice after one wash that a small thread came loose on the waistband, but it hasn't unraveled further. Overall, a decent purchase, but maybe some room for improvement on the stitching detail.
C-In2 Community Discussion
Share tips, ask questions & help fellow shoppers save more
Can you use more than one promo code at checkout? Got a 15% off for signing up for emails and saw another one for free shipping.
Does anyone know if C-IN2 does anything for military discounts? My brother is looking to stock up.
Thinking about grabbing some C-IN2 stuff, but also considering Mack Weldon. How do these compare in terms of comfort and durability?
Anyone know how long shipping usually takes to, like, Phoenix? Trying to figure out if I can get some before a trip next weekend.
How are their return policies? I'm thinking of trying out some of the Zen collection but if they don't fit right, I don't want to be stuck with them.
