First off, the service: ordered these at midnight Dec 21st. They were dispatched by 4am and were with me before Christmas. Given the time of year I was fully expecting to get these after Christmas or even New Year, so very impressed.
The leggings themselves are very well put together. I'm 6', 75kg and 31" waist and the small are a perfect fit. Having recently had knee surgery my legs are pretty skinny so the fit is not overly tight but I'm sure once I'm back to training the compression will be spot on.
