I've tried loads of winter gloves over the years.
The criteria has been must be able to operate the buttons and dials on scopes, callers and digital and thermal spotters and take a shot and load mags all "without" removing your glove !!!!!
I've had neoprene, goat skin,finger-less with mitt overlay, thick, thin. There must be 20 different makes of glove in the back of my truck I've tried loads.
There is nothing worse than being sat in highseat or up on a scaffold tower when its well below freezing and you spend hours glued to the spotter waiting to activate a caller if needed, or waiting for a shot.
After my quest the only ones that have come up good are Tredstep H2O Polar Gloves which are winter horse riding gloves. about £35 a pair so not that cheap.
I've had them over a year now. I can operate all the controls on my thermal and my NV scopes, take a shot, load up the mag and pour a brew from the flask all without having to remove them.
Leading on from this, I was also after some winter clay shooting gloves and the best I've found so far are Wilson Staff winter golfing gloves. I imagine some of the winter cycling gloves are good but never got round to finding out.
