MOERDENG Women's Waterproof Ski Jacket Warm Winter Snow Coat Mountain Windbreaker Hooded Raincoat

Q: Can I wear it in -30 degree weather?

We used it in minus 15 deg, wearing thermal wear inside and normal dress and above that this jacket. I guess it is possible to wear in minus 30, if you wear 3 or 4 layers of dresses. Ensure that you wear a thermal wear and a sweater. You must wear a muffler or something similar to protect your ears and neck. This is extra.
