Best system yet...
I have always had problems with cold fingers. Temps below about 15 degrees would have me headed back to the truck after about 20 minutes, in a lot of pain.
I've got the cold completely beat with this setup...
Base layer: Thin stretch merino wool liner glove - I got mine at REI.
To the palm of my base layer glove, I stick a Grabber Toe Warmer - they're just the right size and they have an adhesive strip. They last about 6 hrs.
Over the base layer and toe warmer, I put an Under Armour Cold Gear liner - very thin, stretch material with a grippy palm & fingers - keeps my finger from slipping off the trigger. These two layers together still give me plenty of flexibility in my fingertips.
Finally, I put the Under Armour Mitts (I would imagine any glommit would do) - the kind with the flip-back top. I cut a slit in the top part that allows me to slip my trigger finger in/out with no trouble.
On the mitts, I turn the flip-back part inside-out and stick two more of the toe warmers in there - one on each side of the fingers.
This system keeps all my fingers toasty warm even when it's below zero.
It's a little bulky, but leaves your trigger finger free - and that's the trick, eh?
If the day warms up to about 25 or 30, I slip off the mitts, still have two thin layers and a warmer and that does the job.
Also, you should be aware that the toe-warmers sometimes puff up like a balloon when they heat - I always wait about 10 minutes in the truck after putting them in the gloves to make sure this isn't happening. If it does happen, you can smash the extra air out before you put the gloves on.
I go through a lot of the toe-warmers, but it's worth it! :thumbsup:
