Can anyone recommend any gloves that strike a decent balance between being warm and having enough dexterity to write with a pen? (touch screen compatible would be a bonus)
My personal preference going from least warm and most dextrous to most warm and least dextrous would go (worth noting that as far as dexterity goes 'least dextrous' still gives a great range of movement):
PIG Delta > PIG Alpha > Outdoor Research Ironsight Sensor
Granted my opinion of warmth will vary from others.
If they are for wearing in the winter anything that isn’t a synthetic material. Suede/leather will always perform better when wet. And definitely priorise warm, cold fingers are fucking useless for changing the fire selector regardless of how dexterous the gloves are.
They're not touchscreen compatible but they have great dexterity & seem ok in cold weather, although I've not used them in *really* cold weather. Writing while wearing them is no problem at all, can tie my bootlaces while wearing them and they don't interfere with gripping things & shooting etc. as other gloves I've tried do.
I'm using gloves from a cheap costume from Halloween, or some old second hand leather viper's. Can't find link for either but they both do as you want but only cost £5....
Had the older version of those for many years, hit the exact right balance I found. There is a PIG cold weather glove now too, not tried it yet but I'm sure they're good.
