C-IN2 has a long history with 2(X)IST, and its founder, Gregory Sovell, is also one of the founders of 2(X)IST, having served as the design director of 2(X)IST, and after leaving the company, he founded C-IN2 to return to the lingerie market and compete head-on with his old club.
 
Gregory Sovell is the design consultant of fashion brands Tommy Hilfiger and Ralph Lauren, and is the core of C-IN2's design team as the CEO of C-IN2.
 
Overall, the quality and design of the C-IN2 are at the mid-to-upper level, but lack of elasticity is a common problem with its products. Compared with other brands, C-IN2 seems to have extremely high requirements for the proportion of cotton, most of its products are made of 100% pure cotton, and only in a few products, the proportion of spandex only reaches 5%, so in terms of elasticity, C-IN2 is a little worse than most of the above brands.
 
C-IN2 also has a wide range of product lines, including skinny boxers, loose boxers, briefs and thongs, four common types of underwear, compared to 2(X)IST, C-IN2's biggest advantage when facing Chinese consumers is the convenience of purchase, major e-commerce platforms have their flagship stores, thongs are its advantage products.
 
6913P1 is its most characteristic product, although the official propaganda classifies 6913P1 as briefs, but from a structural point of view, 6913P1 is undoubtedly a thong. The 6913P1 belt is printed with a large logo, and the distinctive design style has also received polarized reviews in the market.
 
In terms of fabrics, 6913P1 is made of 95% high-quality cotton and 5% spandex, which is comfortable, but the elasticity of ordinary cotton is relatively poor, but from the perspective of fabrics, the price of 188 yuan is not cheap.
 
4002 is also a more popular thong, the raw material is combed cotton, compared with ordinary cotton, its fiber is slightly longer, the overall touch is also better, the design is not as flamboyant as 6913P1, the color difference between the print and the background color is smaller, it is easier to be accepted, and the price of 118 yuan is more pleasant.
 
What needs to be the body type is that the high proportion of cotton also means that the elasticity is poor, and the high comfort is not completely equated, and the standardized size and different body shapes cannot always be completely matched, when buying underwear and other clothes that cannot be tried on, moderate elasticity can also increase the tolerance range of the clothing.
