The Glacierider jacket has the tough 420 Denier tight weave Nylon outer shell, the same as the EXT suits, and warm high density Dacron® 88 Polyester insulation to keep you toasty warm in sub-zero temps and wind chills. The Glacierider suits were Bordow coated to repel rain, wind, and snow. You can find a 1975-1976 Glacierider Woman's Medium Jacket in Black in the morning in my eBay auctions. https://www.ebay.com/usr/dkc_licdist?_trksid=p2047675.l2559 If it doesn't sell there it will be added to my Auctiva store, DollyKamCo-Vintage Snowmobile Collectibles @ www.dollykamco.com or direct https://dollykamco-the-private-collection.auctivacommerce.com/Default.aspx
