Looking for ideas that have worked well for you. Looking to keep hands warm between the temps of 20 degrees down to -15 F. Do you wear a pair of liner glovers like a Merino wool inside a heavy duty glove or do you try and go with just a single pair? How do you attack the cold? All within the context of trying to shoot too.
When I'm snowshoeing into a spot I wear thick wool mitts or some lined snowmobiling type gloves that go well past the wrist, then swap out thin leather "lined" gloves like driving gloves for my shooting. The key is assure your gloves go well past the wrist so you're not losing heat from the wrist area while gloved.
The leather ones are the same ones I use for cool weather so I'm used to working with the camera in them. You don't want wool contacting your equipment in those temps (think tongue on flag pole).
Be sure to store the off pair where they won't get moist, like from condensation. I generally use an outside pocket in either coat or pack.
Using a simple wired cable release for landscapes is a huge advantage since you're not touching the body/lens after you have it set up on the tripod.
On my two extreme cold photo trips I had different strategies: In late winter in Svalbard I had "The Heat Company Heat 3" gloves. Very nice, and despite temperatures of -20F I was cold only twice (without any heat packs added; borrowed a heat pack once).
On my recent trip to Antarctica in (their) early spring I had electrically heated gloves. What a game changer. I had no problems staying on deck for as long as I wanted, and the 3am outing to the mainland wasn't an issue either. Everyone was jealous. They're definitely coming with me next time (and the Heat 3 as backup )
For the base layer, get glove liners available at REI. And over it I put woollen gloves (mitts) with removable flaps so that you can still operate the camera controls with your digits through the liners. The flaps stay attached to the gloves. As soon as you are done with adjusting your settings you can slide the flaps back into position to cover everything. I bought these in Iceland and this strategy works well to as low as -10º C (for some it may be -5º C - will depend on your tolerance to cold). For anything lower, you need to go with something like Stan's solution above.
Unfortunately, my hands become cold fast. Extreme cold temps I’ll use battery powered glove lines like the Venture Heat brand plus the Heat3 mitten/glove over the liners. When walking to and from my car I only wear Black Diamond Meteor mitts or their mountaineering mittens. I’ve found they keep my hands warm while moving around and setting up my tripod, etc.
Make certain you buy the mitten or gloves big enough to hold a thin liner. My hands XXL and tough finding gloves/mitts my hands fit. Before our current chaos I spent cold nights out photographing the Milky Way and temps do get cold. I’ve tried so many different mittens and gloves plus gave away many. Good luck, I hope you find a pair and system working for you.
A couple of steps can help most people deal with the cold. First it is easier to keep the hands warm if you dress well and do not become cold. Second a decent pair of gloves works for many. There are choices for relatively light gloves or fingerless gloves that will work for many people even when temps drop down pretty low.
I have Raynauds and my hands do not tolerate even moderately cold weather. For temps in the 40s or below I need heavy electrically heated gloves or mittens. I am not able to use them for photography and taking them off and on is slow and does not work well. Instead I do not wear any gloves, but keep my hands in jacket or pants pockets wrapped around electric hand warmers. There are a variety of choices with the larger sized warmers putting out the most heat. The battery charge will last about 4 hours.
Another option are Zippo catalytic heaters that run on lighter fluid. The heat level is relatively low and not adjustable but they will run up to about 12 hours on one fill. Another downside is that there is no off-on capability and once lighted the burner will continue until it runs out of fuel.
I have a drawer full of various gloves that I have tried over the years. For me, the Heat3 Smart mitts with the palm zippers, allow you to fold back the mitts. But I usually just stick my index finger through the partially unzipped palm and use that on the shutter button. I didn't like the liners that came with the Heat3 Smart mitts so after a few trial and errors, I settled on the Outdoor Research sensor liners (the heavier weight ones of their 2 models.) It allows me to use touch screens, is heavy enough that if I have to remove the mitts for a short period - no problem. I don't use the 3rd layer of the Heat3 Smart system, the Polar Hood.
I have used this combo now for a few years in temps as low as -40°. I have found that when the temps get below -10° or so, I need to add chemical warmers if I have the gloves partially unzipped a lot. The Heat3 Smart gloves also have a separate zippered compartment tp put chemical warmers in.
Again, YMMV because everyone's tolerance to cold is different.
PS It looks like they have changed their liners, so they may be OK.
The Heat3 Smart gloves are not heated. Heated (battery powered) gloves are kinda iffy in my experience. I tried one set - it was not a good experience. Talked to a few others who tried them and only 1 person I spoke to was happy with them. Maybe others have had experience with the battery heated gloves.
