The hottest gloves I own are BMW's own Winter Glove. Mine are an old vintage but the modern ones are just as excellent.
These are way too warm for me to wear on a day like today (15 deg and climbing) unless you have zero circulation. They are totally waterproof! However, the huge downside is they also have zero protection in the event of a spill.
My go-to winter glove for most riding days are my Alpinestars 365, totally waterproof, the same or better protection than my summer Alpinestars GP Pro's and warm enough for all day riding without heated grips for me. This is on a K12/13S which has reasonable hand protection from the aerodynamics of the fairing binnacle.
With my winter Barkbuster handguards fitted I expect to be able to ride in my summer gloves on all but the worst days.
I have used heated grips perhaps a dozen times in the last 15 years of bikes with them fitted so you can tell I don't have cold mits. On the recent run up to Oulton Park which was a reasonably warm 18-20 degrees (and only 12 when I left home) Richard commented that he had been using his on the ride. I thought he was bonkers as I was fine in my summer gloves.
Alpinestars sizing is worse than my TCX boots sizing. I take a size 10/Large in the GP Pro's and yet need an XL in the 365's.
I also have a pair of Knox SPS OutDry winter gloves. As warm, if not warmer, waterproof and comfy as the Alpinestars with excellent Scaphoid protection (the SPS bit), palm sliders and hard knuckle covers but no fnger protection or outside edge sliders. The downside is the unique (wonder why?) ratchet fastening system which is a bugger to get under a jacket cuff. Large/10 again in these.
By far the best 'winter gloves' I own however, are a pair of Hein Gericke neoprene Lobster Claw over-mitts. These are amazing and live in my Sport Cases all year round. I will never ride anywhere without these on board. They have split fingers, so first and second are in one mitt and third and fourth are in a second mitt, so you look like a lobster with three 'claws' as it were. I was sceptical about these things which are made of the same stuff as wet suits, are fully seam bonded, warm as hell, totally waterproof, pack flat, pull on over your ordinary gloves and have saved my hands on many a long cold wet night when I wasn't expecting cold and wet!
Over-mitts sound clunky and clumsy but the beauty of these is that you can still articulate your right hand fingers for throttle and brake cover at the same time which you can't with a full over-mitt. The first few miles were a weird experience, after that I forgot I was wearing them. Difficult to pick your nose in them though
L to R are Alpinestars GP Pro summer gloves, Apinestars 365's, Knox SPS, Hein Gericke Lobster Claws
