I was really pleased to see a ""basic"" brief being offered in a 95% cotton/5% spandex-type material. C-IN2 has WAY too many options in the 100% cotton version, which I find to be too boring by itself. I currently wear the Prime brief, and the material composition of those are 59% cotton, 39% modal/rayon viscose and 2% spandex/elastane/lycra, but they still aren't as ""smooth"" as I'd like them to be. When I saw the 95% cotton and 5% spandex on these ""Slash"" briefs, and they were offered in white, I immediately bought them. The material composition is EXACTLY the same as some higher-end designer briefs I used to wear for years prior to C-IN2. Those briefs fit amazingly well and felt even better! When the ""Slash"" briefs arrived, they even felt the same as the designer ones I just referenced, and I thought I found a winner. While they feel as if you almost have nothing on at all, the material is just way too thin! In addition, there's something about the cut of the front of these that is just downright sloppy! When using the fly throughout the day, it stretches the front of the brief and literally everything is just ""hanging low."" There's absolutely no support whatsoever with these. The fly doesn't even ""snap back"" into place... it's just wide open! Very poor design and fabric quality! It'd be nice to see C-IN2 focus more on quality pieces and collections vs. all the ""novelty"" stuff they seem to adept at pumping out. An example... taking the ""Core Profile Brief,"" and making it in something other than just 100% cotton so it's a bit more smooth in feel. The waistband size on that is PERFECT, and the color white availability with the design/cut would make them perfect! If C-IN2 stopped with all the novelty and ""stripper wear,"" maybe then, a product like this with a nice material composition could actually be produced with a bit more attention to detail and quality.
