The Beta(Flight Suit) can be adjusted through multiple sizes. It is perfect as a standalone item or used as a system to add an additional layer of warmth below our Ripstop Clothes That Grow weatherproof layers.

Garment Inspiration

The Flight Suit was inspired by Liquid Cooling inner-layers worn by Nasa Astronauts. Rather that regulating temperature, we wondered if we could control contraction using channels.

Organic Cotton

Cotton Comfort: Our flight suit is crafted from durable yet soft cotton, providing unbeatable comfort for your little explorers. Cotton is nature's way of ensuring both comfort and durability.
