I am always surprised by the wide comfort span, temperature wise the double mack has. How can something that comfortable at 40 degrees be warm at zero? However, my camo Fison with the wool ljs,wool shirt, wool vest,plus mac gets possitively intolerable when I put that Norwegian shrunken wool sweater with it. It has to be below ten degrees to add the sweater. I bought mine large enough so that a sweater could go on the inside and still allow movement. They are quite adjustable with the inner sleeve length to a point. That is one can clip the stitching and pull the inner sleeve up, but there is a point where it causes a folding above the tack stitching. Since I am wide in the shoulders and short on the arms, I had a seamstress shorten the inner sleeve at the cuff and retack the inner sleeve, it fits me perfect now. I like how the back game pouch holds all of my stuff, no need for a man purse.
A while back I had to fight to get my coat back. The lady that use to manage the local gas and puke, put it on and wouldn't take it off. She always thought that I was the fanciest dresser that came in there,when she managed it the food was great, I was wearing my Fison pants, shirt and brown wool vest combos, no coat. She thought that I was crazy for dressing up just to go hunting. The other day she saw the whole ensemble and wanted to try on my coat, now she is a pretty lady, but I just couldn't let her make love to my coat the way she was going on about it. she has one that fits her for herself now and she came by to show me how it looked on her. I have been trying to get my wife to get a Filson for years, she will have no part them.
