Finally, a layer for you! We've taken our best-selling sweatshirt and translated the design to grown-up sizes. Because let's face it: our little explorers aren't the only ones climbing, splashing, and spilling ;)

Whether you're looking to match with your mini-me, or strut your stuff solo, this cozy sweatshirt is designed to handle everyday wear and exploration. It's made from a combination of sustainable Modal and cotton, with just a touch of spandex for that comfy stretch. Plus, our fabric is enhanced with gold, so that it fights off odor, stains, moisture, and bacteria. A sustainable product, purpose-built for adventure.

Why We Love It

An adult sweatshirt built for adventure:

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

* Built from natural fibers like Modal and cotton

* 100% California-made: cut, sewn, and designed in San Francisco

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

Sizing and Fit

This is a unisex cut, designed to support movement and comfort. The models are 6'2" wearing a size large, and 5'8" wearing a size small. You can treat the sizes as closest to a men's size.

Materials

68% Modal, 27% organic cotton, 5% spandex.

Fabric is enhanced with gold through a non-chemical process. It is left soft to the touch while naturally and safely combatting bacteria, moisture, and stains.

Tough AND cozy

Yes this sweater is comfy cozy, but the truly impressive part for me was that my 4 month old hit me with a wave of spit up this morning and I just wiped it off with a burp cloth - visually can’t even tell and I just smelled it after wearing all day and no milky spit up smell.

I got onyx in a small - 5’6” 130 lbs

Beyond cozy!

A perfect balance of light and warm, comfy with some elasticity, and a lovely color too (kelp). Perfect for layering especially for those of us folks that live in climates like SF!

Best Sweatshirt!

I’ve purchased FP clothing for my child since she was 6 months old, she is now 4! When I wore this Sweatshirt I instantly realized the comfort & quality that our kids have been getting with all the clothing! Thank you for making this for adults and I can say the fit is perfect - ordered a small, for myself: female, 5’6”, ~125 hiker build!

The best sweatshirt I’ve ever owned

I have worn this sweatshirt every day since I got it and this is already my new go-to sweater. It’s just the right weight for a cool fall day and it’s so soft and comfortable.
