Wore this up Snowdon at the end of Jan 2024. Plenty warm when coupled with a t-shirt and fleece underneath. Great at stopping wind from reducing temperature. Underarm zips help with ventilation. Zip pockets open easily to get at snack bars and your mobile phone. Draw cords on hood helped the hood prevent my peaked beanie from flying away. You probably want a cap or peaked beanie under the hood as there's no wire to help it keep it's shape. All in all, very pleased.
