This is a Woman's size medium Vest Top Racepants from a 2 piece snowmobile suit from the mid 1970s. Original Arcticwear from Arctic Enterprises Inc., of Thief River Falls, Minnesota. These racepants have the tough 420 denier nylon outer with a nylon lining and Dacron 88 insulation. Arctic Cat is well known for their premier vintage winterwear and accessories. They were among the best in that time period. This is one in my collection of vintage snowmobile suits and snowmobile clothing. I offer many of my items for sale on eBay and in my store at www.dollykamco.com
