This winter balaclava from M&S is a cosy cover-up for cold school runs and playground mornings. Pulled on in seconds, the hood style wraps around little heads and necks in one easy layer, so there's no fiddling with scarves that slip or hats that fall off. A touch of stretch helps it move with them, from scooter rides to snowball fights, while the soft knit stays comfortable against the skin. Simple and practical, it's an easy grab for chilly days whatever the adventure.
