This Mac in a Sac children’s rain jacket is designed to keep young explorers dry when the weather turns wet. It’s a straightforward, reliable layer for daily wear, ensuring kids stay protected from showers without weighing them down.
With a 10,000 mm water column rating, this jacket resists persistent rain and splashes, while its 8,000 gsm breathability lets moisture from active play escape. That balance helps prevent overheating and clamminess, so little ones can stay comfortable whether they’re splashing through puddles or running errands with the family.
The waterproof rating—measured as the height of a water column the fabric can withstand—means this jacket will hold up under moderate to heavy rain. The breathability figure (grams per square metre per 24 hours) indicates how much water vapour can pass through the fabric, keeping the inside feeling drier even during energetic activities.
