Wacoal CWX These women's leggings offer full lower body support and comfortable wear. - Model Name: GENERATOR MODEL - Gender: WOMEN'S - Support Type: Full lower body support - Color: Black - Size: L When worn during mountain climbing or exercise, I feel like they definitely reduce fatigue (this is just my personal opinion, lol). I feel like I have less muscle soreness the next day! Also, I think they reduce swelling (*´꒳`*) The design is plain black, so I think it's easy to match with any kind of wear. I bought two in different colors, and since this one is unused, I'm putting it up for sale. Marathon Supporter Spats Sports Correction function
