Meet our newest, snuggliest addition
There’s nothing that captures the spirit of outdoor exploration quite like a cozy flannel. But we couldn’t just go with any old materials — we wanted a shirt that could stand up to mess, while also being great for our planet.

The snuggliest layer, all year round! Our eco-friendly, super soft flannel is made from Seawool, a fabric that combines upcycled oyster shells with recycled plastic bottles and polyester, so it’s great for our planet and coastal communities. It’s also naturally anti-odor, anti-bacterial, anti-static, quick drying, and extra soft. That means your little one can wear this shirt for longer, with fewer washes along the way.

Our products intentionally run a bit larger, so that your little one can wear them for longer. We recommend purchasing items more “true to age.” In these photos, our just-2-year-old model is wearing a size 24 months.
