@Bob Nelson 35Whelen — Bob, with 50 million “Sheep” where you live can’t you get some good WOOL to keep warm? I’ve paid big $$ for top of the line wool hunting clothes and worth every penny, lasts forever and nothing (Nothing) is warmer then wool. Some of the best quality use to come from King of the Mountain or Sleeping Indian —- their older stuff selling used on EBay can be excellent condition…and still cost $300 to $800 “used” for a shirt/pants/coat. 2nd best quality like Filson is also very good AND expensive. An older friend in Canada got me sold on wool back in the 1990s and later when I owned a cabin and acreage in NY Adirondacks I amassed quite the collection. That stuff kept me warm enough to stay on Stand for 5-6 hours in Zero down to -10 F. The downside (besides the cost) is the weight & bulk - it’s like carrying a “live sheep” on your shoulders, so I carried my coat when walking out to my Stand…then put it on. It also doesn’t pack easily for travel-away-hunts. But - Wool long johns, wool shirt & pants, wool vest, wool coat, wool hat and you’re ready to Hunt GREENLAND for Musk Ox in February !!
