The Buttersmooth Luxe material feels amazing! Sounds weird, but I couldn't stop running my hands along the sides LOL. It feels soft and smooth, but the material is sturdy and doesn't feel too thick or thin, and was nicely compressive. The length of these bikers are perfect and the shorts didn't ride up at all while wearing them during a HIIT workout. The waistband also didn't roll down or do anything weird like with previous high waist bands (Marble collection bikers). It was also nice because even though I sweat a lot, the sweat didn't show through the heathers color. I hope more collections are made with this material!
For reference: I'm a size M in bottoms, 130lbs, 5'3" , waist 27", hips 38"
