Meet our snuggliest, most durable layer

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.

Why We Love It

These baby clothes check every box:

* Bacteria- and odor-resistant fabric that keeps its shape through multiple wears

* Tag-less for no itchy annoyances

* Built from a combination of upcycled and recycled materials

* 100% California-made: fabric sourced in Los Angeles; cut, sewn, and designed in San Francisco

* Eco-friendly shipping: compostable envelopes, recyclable wrapping, no plastic

Sizing and Fit

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 the first photo, our just-2-year-old model is wearing a size 2T.

Seawool combines discarded plastic bottles with crushed oyster shells to produce a soft, anti-odor, wicking, thermo-regulating fabric that feels just like your favorite flannel shirt. It’s a sustainable, eco-friendly certified fabric that’s great to wear and great for our planet.

Wearing this shirt every day

My kid just turned 4 and this is such a great shirt for lots of occasions. Wearing every day is so easy. The edges don’t get turned up and it perfectly hides any spills or dirt. It looks like a special occasion shirt but is also super soft and comfy. I picked it for a special birthday party and everyone was complimenting us. Will definitely get another once this is too small.
(If you see the photos and it looks weird, that’s because my kid will only look into the wrong end of binoculars)

We can’t wait to wear this flannel!

We were so excited to get our flannel in the mail! The fabric is so soft and my daughter is equally obsessed with it. We live in the northeast, and I’m so excited for this to be a warm layer and staple in my daughter’s closet. The color is also rich and amazing (we got the blue!) Looking forward to buying more from this awesome brand!

Uncommonly Soft!

Our baby is LIVING in this flannel. Literally, she is on day 3 in it. It is so soft, so cozy, and obviously it still doesn't smell. First Peak Magic!

Soft & stylish

This flannel is insanely soft and snuggly, and it looks like something I would buy for myself. Highly recommend.
