Merino wool underlayer is warm even when wet and it wicks moisture fairly well and breathes. Technical trousers and jackets for breathing because wading in the snow is hard job like jogging and you're gonna sweat. So the sweat needs to be dissipated. Mitten for colder weather and grippy discs like FLX or rubber. Note that Vibram rubber is less grippy than older grippier FLX blends after a year even though when new X Link medium is grippier in putters than FLX. After washing/rubbing the lube off of the Vibram discs. A more nature friendly way to disposable hand warmers if to use a reusable acetalsomething heat package that will heat you nicely for 20 minutes per palm sized pack. They are recharged by putting them in hot water. They use a metal plate to activate the heating process and in something like 10 F they are inside a frozen solid mass of the warmer an can be hard to activate kinda defeating the purpose. Especially if you're in danger like freezing the fingers off (almost happened while not golfing 2 years ago) so it is good to have a backup. Like a disposable warmer. There are footwarmers too but they are more expensive than handwarmers and i've heard some say that people can get burned by putting hand warmers in a shoe from too much heat. Another option is to use electrical heating like Hotronic FootWarmer or similar products. Aviators, military and motorcyclists have clothing that uses electrical wiring inside clothing to warm you up and those tend to be very expensive and those made from metals can be brittle so an expensive failure. Some use batteries instead of the electrical systems of the plane or the bike. Some have more durable wiring than iron or steel. I haven't heard of functioning cheap electrical heating. Unless you build one yourself and then it is iffy.
I haven't experimented enough with my FootWarmer to say which is the easiest way to use it but it works fine in above freezing temps Zip Loced with the pouch being filled with polyester wool and the pouch being inside a pocket. I'd need to buy an extra large mitten to fit the FootWarmer inside for easy operation (buttons to push and flat wiring to avoid from bending to breakage) like putting the hand into the mitten after throwing just like a normal mitten. While maintaining dryness because electricity and water don't mix too well and the heater gets hot enough to melt snow. Perhaps an extra large mitten with the battery attached (comes with a clip) put inside a Zip Loc would work. That has been the plan for when it gets so cold that i'll get problems.
A cheaper solution would be fisherman's glove or sports glove with grip enhancers that is thin enough without large seams to allow a good grip even while putting. I have not found perfect gloves despite trying on a couple of dozen of different ones. So if you're hand and have access to thin thin seam durable gloves that you can coat with some sort of grippy material like soft tacky rubber or sand for abrasive grip you should have enough grip and some warming up. I have thrown with glove on at times in the coldest part of the year and i have put the gloved hand inside a mitten in between the throws for simple and nice solution. I got the FootWarmers this fall so i have no snow experience with them yet nor have i used mitten/ Zip Loc in practice because all the mitten i have are too small. Which reminds me to go to a store to see if can find a large enough mitten to try this idea on.
Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.
