my problems with Tillman date back to when they first started producing in china. (early 90s?)
first, I noticed the white gloves would bleach my skin whiter when new, really disturbing.
second, the leather was very inconsistent it thickness, and some pairs would have a finger disintegrate in a matter of days.
I stopped buying Tillman, and now buy Steiner or Weldas. I like the Steiner megatig 0230, it has a layer of insulation on the back of the fingers, that gives them a little more protection without compromising feel much.
the Weldas green and white gloves made out of buffalo hide are nice, a bit thicker, but they do seem to last longer. I don't have a pair around, so don't have the number.
