Wardrobe Recommendations

• Treat this like extreme cold. Wear a heavy parka, insulated snow pants (if outside longer), and two layers on hands (thin gloves + mitts).

• Cover all exposed skin: balaclava or face covering, scarf/neck warmer, and a warm toque that covers ears.

• Footwear: insulated boots with thick socks (avoid tight boots—reduced circulation makes feet colder).

• Plan smart: shorten outdoor time, take warm-up breaks, and keep a charged phone + emergency gear if travelling.

Weather Trivia

A -45 wind chill doesn’t change the air temperature—but it shows how fast your body can lose heat in the wind. That’s why frostbite can happen quickly, even if the sky is clear and it “looks fine” outside.
