How about punching some holes in the leather to cool your arm
I just recently punched out holes where it was possible. I didn’t want to punch out any to where the sting could hit the arm.
This is the second arm guard; it is the 1st that I lined with deer skin thinking that would fix the problem.
I don’t think it’s the tanning or dye, I used it for 30 minutes and took it off and it was already soaked. It actually fits well on my arm or should I say it lays flat. I will try baby powder, I just didn’t know enough about leather and wasn’t sure if it was ok using powder.
