C3fit is a sports compression clothing brand from Japan, and its concept is to shape the body through 3 "Cs", which stand for Compression, Conditioning and Comfort.

Chinese sports enthusiasts may be relatively unfamiliar with C3fit, but in fact, it has received a high evaluation in the Japanese technology sports equipment market. C3fit's long stretch leggings, leggings and stockings have been certified as "General Medical Devices" by the Ministry of Health, Labor and Welfare, which can effectively strengthen the return of venous blood from the peripheral to the center, and reduce and prevent the poor flow of venous blood and lymphatic circulation.

IMPACT is the flagship series of C3FIT, the product has the strongest compression performance, and has support for the thighs, calves, knees and waist, which is suitable for sports enthusiasts with knee injuries and back injuries, as well as runners who like high-intensity trail running. IMPACT is also subdivided into two sub-series, IMPACT and IMPACT AIR, where IMPACT has a higher compressive strength, while IMPACT AIR has a slightly lower compressive strength but is more breathable.

C3FIT also lays out the basic INSPIRATION series in China, which has a spandex content of 25%, moderate compression, easy to put on and take off, and good comfort. As a basic series, INSPIRATION does not have support strips on the knees, waist, legs, etc., so it is suitable for speed runners or runners who do not need support protection.

In addition to the basic INSPIRATION series, the ELEMENT series is also a popular series. Compared to the flagship IMPACT, the ELEMENT collection also has a supportive design for the waist, legs and knees, but it has a more athletic fit at the knees and a placket zipper that is easier to put on and take off, making it suitable for first-time compression wearers.

C3FIT has only more than 10 stores in China, which is relatively more convenient to buy online, and the price of its compressed clothes is concentrated between 500-1000 yuan.
