I have one and they are bomb proof. He only uses Army wool blankets to make them. The first thing he does is wash and shrink the wool. There is a 45 minute video of him sewing one of them up on youtube all the seams are double or triple sewn. They are very well thought out piece of outdoor gear. If you want a pretty one you find an old Hudson Bay or Pendleton blanket he will "murder it" his term. I do not own any of Asbel's Wool so I can not give a side by side comparison.
Be sure your able to still do "pull overs". I found I can't. I bought one of Teresa's and ended up taking to a local seamstress and having it split up the front and put a zipper in it.
Looks interesting but super expensive. I tried to read the description and couldn't make it thru the first 2 paragraphs. They must speak a different language up there. What's a fat bike? Is that like what napoleon dynamite used to make his killer jumps with? R
Sounds like he is catering to the well off "young sports", not so much hunters.
He is heavy into biking mainly offroad, a Fat Bike is a fat tire bike. They are used for riding soft surfaces sand and snow. He mainly makes for hard core winter campers and bushcrafters. He does have that Northern MN, Iron Ranger vernacular though. They are expensive but you get what you pay for. If you want to watch his process on sewing them here is a link.
