I like my Hobart full leather jacket from Tractor Supply Company. The sleeves are lined and it is very comfortable. I'm also in school and it did get a bit too hot for a few weeks after we started class back in Sep. Then I used my leather cape I bought from the LWS but the sleeves are not lined and on hot days my arms looked like I had one of those cheap spray-on orange tans. I only really use them for welding overhead. Though right before Christmas break I wore the jacket just because it got so cold in the shop!!
