Super cute and great quality but it runs large. I'm a size 6 and the medium as two to three inches too big in the waist. I exchanged it for a small.
Lost my favorite Smiths so bought the PIVLocks and loved them so much I bought another pair and recommended them to my friends. Great for tennis, running (even in the snow), XC and Alpine skiing, and mountain and road biking. Fit under all my helmets and don't fog up too bad in the cold. Love the warranty too.
