Rapha, nice but a bit pricey?

JF goes off to google glove base layer. TBH I'm not sure there's room inside my current glove, which is a Troy Lee XC, and vey tight. Plus the deFeet is only 14 squid. All the continental pro's use them

They're very thin so should be able to fit under your current gloves. Would recommend getting some. As in other clothing it's all about layering, and trapping layers of air in between.

You can try these here. Or any outdoor/ski store should have them.
