Scandinavians do not believe in bad weather, only bad clothing, and Polarn O Pyret has been proving it since 1976. Their whole range is a layering system: a base that regulates, a middle that insulates, a shell that takes the weather, all in organic cotton and merino, all built tough enough to be handed down twice. Here is how we would layer a child for a British winter, from the skin out.
The shell: Waterproof shell jacket STORMY

Polarn O Pyret · Swedish organic, built to be handed down
Waterproof shell jacket STORMY
Wind and waterproof with fully taped seams, built for the kind of British day that ruins lesser coats. The Polarn shell that other shells get compared to.

Polarn O Pyret · Swedish organic, built to be handed down
Windproof fleece jacket
The insulating layer that goes under the shell when it turns, and works alone when it does not. It snaps into their jackets so nothing flaps loose.

Polarn O Pyret · Swedish organic, built to be handed down
Long-sleeve bodysuit merino wool jacquard
Merino against the skin, which stays warm even when damp and regulates a child better than cotton ever will. The quiet first layer that makes everything else work.

Long-sleeved top striped
The organic cotton stripe Polarn built its name on. Soft neckline, shoulder snaps on the little sizes, and the kind of thing that gets handed straight down.
