What is the best way to keep warm while outside playing a Winter sport

A nice warm coat with a hat, gloves, scarf, and Earmuffs.

Ski and Snowboarding. l sweat doing all the time:)

Do not stand still.

thermals, sweater, jacket, thick socks, good shoes, head gear and mittens or gloves.

good luck on your game!!

Layer your clothes.

wear a thermal shirt under your jersey

put something on your head or ears. In the cold, 50% of all heat loss is through your head.

Gloves would help too if you can get away with it.

Bundle up in everything you got.

waterproof outerwear ex snowpants and jacket. beanine. gloves (also waterproof). boots- warm ones

Go fast and hard and you wo not get cold!
