I'm sure it will be. I'm just saying that I'd wear some half-decent gloves. Your hands get plenty of blood supply, and it's relatively easy to keep them warm.
Your toes, OTOH, don't get the best blood supply, and it can be really hard to keep them warm. I've worn cheap fleece gloves that let the wind through, camping and hunting in Montana when it was 0 to 20 degreees, and my hands were fine. My toes, OTOH, felt like they were going to fall off, they were so cold, and I was wearing 600 gram Thinsulate boots.
So I reiterate, just get gloves for your hands, but spend your time and money making sure you are keeping your FEET warm. You can hold your bare hands near the campfire in the evening, for that matter, but you will melt your boot soles trying to re-heat your toes that way.
And UnderArmor ColdGear long underwear is great stuff, worth the $100 a set, because it doesn't bunch up at all under your clothes, but adds a great layer of warmth.
I've spent most of my life in the Soutwest, and Boise's climate is not like Northern Idaho or Western Montana. It's desert hot here half the year, then it's mild but can turn fairly cold for a few months. So I'm not all
that much more acclimated to cold than an Arizonan.
Toes, my friend. Take care of your TOES!
