I am pretty new to the MYOG community, so bare with me as I try to be clever and original (and probably fail miserably) by stepping away from the tried and true methods and materials.
Since winter is coming, I'm focusing alot of my attention on mountaineering gear. And I'm making some Goretex overmitts, and I was wondering what the collective opinion of using spray rubber over the goretex for grippy palms.
Is it durable and flexible enough in sub zero temps? Is there a particular brand that would work best? Or should I just stick with slip-not?
