I've worn these twice, but they don't fit, so I'm selling them. I've removed the drawstring from the waist and have lost it, so please be aware of that (see photo 4). These are tight tights, so you can still wear them without the drawstring. These are lightweight and cool support tights, recommended for hiking, trail running, running, and other activities in warm weather. Mesh material is used extensively in areas that tend to trap heat, such as the groin and thighs. The high breathability reduces heat buildup and stuffiness. Furthermore, they support the lower back to stabilize the core, and are designed to firmly support the knees from above, below, and the sides, which can be a source of anxiety. The weight is 112g (men's M size), the lightest model in the existing C3fit tights lineup, while still maintaining a solid support effect.
