Sometimes you cant skimp on gear. Spend 100$ and get yourself a nice quality pair of mitts. I love my hestra heli mitts they are crazy warm. With tons of liner options there's plenty of possibilities.
Just got a pair of these. They seem warm and bomber. Come with a packet of nikwax to cover them in. I'm excited to see how they hold up. So far I've always had good luck with FlyLow shit.
last year bdogs . i live in quebec and i go ski on -35 celsius and they're warm as an oven ! don't be frightened by their little size it works! also dakine for those who mentioned it is a great option
