C3fit Inspiration Long Tights Men's S size, Black Brand new, unopened I am selling these as I haven't used them and they have been in storage. These long tights are a medical device ("elastic stockings") with graduated compression design. The compression promotes blood circulation, reduces swelling, and leads to better physical condition. They use a soft, skin-friendly nylon-based material. Special tape is applied to the seams (Smart Seam processing) for a flat skin surface. The waist area has a stretch core bonded to the fabric, improving the feel and fit against the skin. They are comfortable to wear for long periods with minimal stress. In addition, C3fit's unique three-dimensional design prevents slippage during exercise and bunching of fabric behind the knees. They also have UV protection (UPF30-50+, UV protection rate of 90% or more *data at 30% extension). They are useful for sports such as running, trekking, and golf because they improve exercise efficiency by suppressing unnecessary muscle and fat movement. Furthermore, they are widely useful for everyday standing work and long periods of travel.
