That looks really good. And personally, having some of those good Highlander genes, I have a very high tolerance for cold, so I prefer the 13 oz material.It looks great, and I don't die of heat exhaustion in them. Except in the summer. I made the mistake of wearing a 13 oz'er to the Highlands Ranch games last August. It broke 100 and I thought I was going to DIE. We had to leave early. I have never left a festival early before...
