The best gloves, hands down, that I've ever used were ones that I bought at Rolex many years ago.
They were made out of this ethiopian hair sheep leather and were insulated. The leather is indestructible. They have lasted longer than any other gloves I've ever had. I would give my eye teeth to have another pair because after many years of winter riding 5 days/week they are showing some wear.
I would be forever grateful if someone knew who sold these/what brand they were. I also had a pair of the summer ones that I lost :sob: and they were equally excellent.
The SSG ones do not cut it in my climate.
