C-IN2 rank low in my overall hierarchy of underwear because of the material they use. It's mostly cotton, which is fine for FTLs (-_-) but unacceptable for the $15-60 dollar pair of designer underwear that one can easily shell out.
For one thing, the colors don't stay vibrant very long with 95% Cotton/5% Elastane construction. The second thing is that they don't "breathe" the way they should or could were they made with a nylon pouch. The other thing is that these, like the 2(xist) line from C-in2, have too much fabric from leg opening to waist band. That's great if you have an unusually long crotch area, intend to sag and want to show off the waist band of your briefs, or enjoy that old timey grandpa's underwear fit. Most people don't though so beware.
They got it right with the interior cup (as opposed to their sling designed underwear) though. In an overall underwear shoot out?
I'd give these a 2 out of 10.
If they were only stacked against other C-in2 briefs? I'd give them a little bit higher mark for getting right what they did.
3 out of 10.
