Actually, my current set of gear appears to be fine at 15F. As it gets colder I will need to replace a few items. Plus, my old ski gloves do not have much flexibility.

I was more curious about the handwarmers as an emergency measure.

Now if my Burley jacket ever gets here....
One month being backorder is a bit obnoxious. Come friday and it still has not shipped, I'm cancelling the order and visiting a LBS or REI.
