These things are a bit on the old side, but Siver was a SWEET company and these are in great shape. Good venting, barely any scratches from skis or anything, perfectly warm but not overly so, very comfortable. Size medium, with an adjustable waist, fit my 32" waist perfectly. Great pants but I'm patrolling full time this winter and upgraded to some Patagonia Rubicon pants that'll hold up to the abuse of 100+ days of skiing more or less in a row.
