Sorry, dyslexic moment.

460s not 406s.
I've tried the 460s (or similar) before, they were too bulky for me.
Those are the ones.
I agree, they feel bulky but as I've said, only for a short while till you're used to them. Then they are exactly the same as any other glove.
They're warm as toast; truly exceptional in that regard. They also pretty much fall off your hands when you need them off as they are quite a loose fit.
I buy two pairs (normally from eBay; if you can wait they come up at daft prices). One pair goes on in the morning until the insides get damp. Then onto the van vent while I wear the other pair. End of the day, onto a radiator held open with either a ball of foil or a tin can with both ends cut off.
I understand they aren't perfect but I
never have cold hands in winter.
