These blue Perfect Moment Aurora skinny ski trousers feature a slim fit, a soft fleece lining, a contour fit with protective kneepads, elasticated inner cuff with snap closures, and extendable flared hems with zips. Did you know that the Aurora Borealis is a display of lights that show the Earth's magnetic field interacting with charged particles from the sun? Sounds dangerous (but not as dangerous as you heading off on your next snow adventure without your Perfect Moment pants).
