I think that next to saddles, I've probably tried more types of long fingered gloves than any other component or piece of apparel. Still looking for the perfect glove.
I've tried Pearl Izumi (2 styles), Gore, Performance (and probably more) and have just ordered a pair of Giordana's. My favorite glove has been the PI Gel Lite that is probably 4-5 years old. While it has some type of mesh outer fabric rather than the the windstopper fabric, it actually seems to do a much better job of keeping my fingers the warmest. I've kept the Gel Lites going with yards of sewing thread stitching up holes that keep popping up-especially in the ends of the fingers where I shift.
All the windstopper fabric I've tried just seems to be a bunch of hype or junk. It doesn't seem to slow down the cooler air-or keeping the ends of my fingers from getting numb one bit. I have learned that a little larger glove is warmer than a tighter fitting glove-and works a lot better when using a liner.
For temps under 45 or so I use a synthetic glove liner......but when temps are in the 30's or bleow it only works well after I've hit a hill or two and get really warmed up. Please tell me there is something out there that it not to large and bulky to easily work shifters and will keep my fingers nice and toasty.
