Hello, I have a pair of pants that have the Lahco brand. It's a pair of stretchy pants that have a leather band around the bottoms with a square opening in the leather on the outer legs. It has CIS patch on the front. I don't know what year these are from or if these are ski pants or equestrian pants or???. Any help in dating these and what these were used for would be much appreciated. I've attached a photo of the label and leg bottom. Thank you.
