Outer: 10,000mm Waterproof & Windproof 100% Recycled rPET Tricot Shell with bonded 100% Recycled rPET Microfleece lining

Made from sustainable recycled materials with recyclable packaging. 

Designed for real life, this softshell onesie keeps little ones warm, comfortable, and protected through changing weather. With a 10,000mm waterproof-rated & 100% windproof outer, it easily handles light rain, harsh wind, and even snow, while the soft, stretchy fabric and cozy microfleece lining keep them snug from head to toe.

Free from harmful chemicals, it's easy to layer and designed for all-day comfort. The fleece lining provides warmth without padding, so it's safe in the carseat (provided no padded layers underneath). From crawlers through to puddle jumpers, this versatile suit is an ideal choice in chilly, rainy, or snowy conditions. 

Note: seams are not taped. For heavy rain we recommend our SplashMagic or 10K range of rainwear.
