The trouble with gloves is that your hands get hot if the sun comes out. On our last trip I tried to overcome this by wearing finger-less cycling gloves but these aren't leather they are some kind of technical fabric and didn't give me any grip on the wheel.
As a result I've been doing research on gloves and have found a firm called Dents, which is based in Wiltshire in England and has been hand making gloves since 1777. They made James Bond's driving gloves for Skyfall - how cool is that!
I bought three pairs of gloves from them:
Finger-less unlined driving gloves for normal driving. I tried these out on a roof down drive on a cold spring day last week and they were most excellent.
Full fingered, string-backed and lined driving gloves for cold weather. The string backing stops your hands getting too hot.
Full fingered, string-backed but unlined driving gloves made of peccary leather which is supposed to be the best possible leather for gloves. However I found that the lack of lining exposed the seams internally and that they were not comfortable and so they went back to Dents for a refund.
