Have hestra myself but I've given this some heat
Obviously not excellent enough - even these gloves will struggle with -31 degrees :) If anyone can point out a better deal I'd love to see it. I was looking at the Hestra Heli's too but at this price I couldn't resist.
Excellent price, torn between black diamond and hestra ones. I fully agree that once you invest in decent ski gloves you'll never look back. I wish that I'd bought decent ones years ago! Cold (& wet) hands can very quickly ruin your whole day on the slopes.
