I've used the Exo2 gloves, and they are just brilliant - there are no elements as the fabric is the conductor, they don't get hot but just a few degrees above body temp.

On the down side, wires.... and they are rather stiff, and you are right about the cuff and water ingress in heavy rain and slow moving traffic.

I found them too warm so I sold them.

There are some heated inner gloves, but you are still going to have wires. Kies have batter pack options which might make a difference ?
