From Lululemon: Waistband drawcord keeps your shorts in place so you don’t have to pull them up Hidden pocket in the waistband has space for your card and keys Our fastest-drying fabric Breathable Sweat-wicking Four-way stretch Supportive Feels cool and sleek on the inside, soft and brushed on the outside Added Lycra® fibre for stretch and shape retention -- Like new. Worn twice. Washed in a garment bag with dye free detergent and hung up to dry both times. Selling because these unfortunately ride up on me. The Wunder Train is more compressive than the Align. If you have bigger thighs / hips, I would size up in these or get a longer inseam so they don't roll up. Color is very accurate to Lululemon's site. These are great for running and high impact exercise; the material is very sweat-wicking. They basically come out of the washer dry.
