I spent a few months keeping an eye out for a great pair of sporty winter gloves which weren't too bulky but still gave good warmth, were waterproof and had lots of protection like hard knuckles etc.
I found them!
Belstaff Thermo Sport.
Pittards® Armor-Tan™ leather (ceramic impregnation enhances abrasion resistance) • Thinsulate® thermal lining • Carbon knuckle guards • Side palm protection • Cuff and wrist adjuster • Kevlar® reinforcement inside.
Warm, comfy, easy to feel controls, not much more bulkier than a summer glove. Waterproof. They feel strong, solid yet very pliant and easy to move my fingers in. The leather is soft and the armour feels tough. I expect that they'd really hold up in a crash. Warm enough for winter, cool enough for English summers.
Lack a rubber wiper for clearing visor when raining.
Don't have an inner cuff to go inside jacket and prevent rain from running down my sleeve and into the glove.
Absolutely recommend these. It's like holding a hot cup of tea! Even with the Thermo Sport gloves on above I can really feel the heat, it can actually get too hot.
I've got the Daytona heated grips which are the same thickness as regular grips. The wires are small and almost invisible if it's tidily fitted. The switch is easy to operate with gloves on and has an Off, On and Start settings. The Start setting is a boost setting for extra heat. On is a mild setting so you get the bars kept a bit warm. Somewhere between the two is ideal so I tend to spend 10 minutes on Start, then 10 minutes at the On setting, and just change them when necessary.
