This is a superb ski pant. It works well in regular temps with a light capilene layer beneath, but the adjustable waist that stays up on a nice day (not recommended for dude riding) can also accommodate my superwarm fleece bibs underneath when the temps get bitter. I ordered the med size at a waist of 33 to 32 depending on brands and adding fleece was fine, and still had good mobility. and if you get too hot, the side vents blow the steam out fast. The only caution I might add without dinging a star rating is be careful putting them on in a rush, the hook on the gaiter will catch your toenails. Otherwise, buy them and go to fun cold places in them with confidence.
