Wolven is a wonderful fitness brand and these are three lightly used sets (minus the black shorts) of mine from them. Here's what the website says about their materials: "Ultra Soft Breathable Quick-Drying Odor Resistant Four-Way Stretch Made from 84% rPET and 16% spandex, our signature four-way stretch fabric is ultra soft, breathable, quick-drying, and good for the planet. Our fabrics feature a vegan suede finish and are odor resistant." Any further questions, please ask Selling all three SETS together, minus the black shorts as that was recently sold separately.
