I was looking at simmon bliz just because of configurations that they offer. But I am open to any maker price is not an issue. I also really like Eastman leather 1942 Irvine. But sadly my size 42 is sold out & have to wait for two month to get that. Is there advantage of horsehide vs regular steer. I mean I know horsehide give it more structure & support etc. But would regular steer be that bad? And you think I should up my sheepskin to 22 mm? Kind of surprised that you get cold at 5f with 3/4 inch sheep skin.
