I found these at a sporting good store on sale. I bought two pairs in black and ended up buying two more. I am 5'3 and normally weigh between 132 and 140 lbs. I bought these in size medium.
They are made of cotton and Lycra and they have superior wicking qualities and they also dry quickly. These capris provide really good coverage, aren't too clingy, comfortable, and are adequately long to cover the scars on my knees from surgery.
While these are great as work out pants, I also wear them around the house and have even slept in them. I normally buy a pricier brand that is comparable but also cost almost double for what I paid for one pair of these.
Good fit, quality, and price make these a no-brainer.
