Kinda curious as well. I'll have some input as to the pipe gloves after Christmas most likely. But they're pipe gloves, so I don't really care too much about the warmth factor...
I have two sets and I think most in the line use a Primaloft insert. My hands usually get cold but the Sonora & Convict have kept my hands toasty. No rips, cuts, or blemishes so far and the palms are super soft with a great feel!
