  • Best for: Parents who need a flexible jacket for variable spring and summer conditions

Three wearable options combine a waterproof outer shell with a lightweight microfleece inner. Detachable hood and taped seams increase resistance to rain.


Stay dry during heavy showers - thanks to taped seams and 2,000mm waterproofing

All seams are taped to prevent water ingress and the outer shell has a waterproof rating tested to 2,000mm, creating a barrier against sustained rain. A detachable hood adds coverage where needed.

Reliable wet-weather protection keeps children dry during downpours, ideal for puddle-loving youngsters and wet playgrounds. The taped seams reduce the risk of water seeping in at joins.

Layer for comfort and warmth - with a lightweight microfleece inner

The inner layer is a very lightweight microfleece that traps warmth without bulk, while an anti-pill finish keeps the fabric looking new. The 3-in-1 system allows separate or combined wear.

Wear the fleece alone on cool days or combine it with the shell for chilly, wet weather. The anti-pill treatment maintains a neat appearance through repeated use and washing.

Practical everyday use - thanks to zipped pockets and stretch cuffs

Zipped pockets secure small items during play and stretch cuffs create a snug fit around wrists, helping keep out drafts. Detachable hood simplifies cleaning and storage when not needed.

Secure pockets prevent lost treasures and the stretch cuffs help keep sleeves in place during active play. The detachable hood makes transition between seasons straightforward.
