It was like -12 at the top in Nozawa too,
I never really felt the cold as I have really good merino wool base layers, socks, leggings and long sleeved high neck top.
I highly recommend it, super warm and it dries out super quick too.
The powder was just amazing, am a bit busy today but will post some pics and more info later.
I am seriously thinking of getting a Jones hovercraft because the pow is so amazing this year. I spend most of my time in the side country and the runs are pretty long.
How are your boards coping with the pow?
