Our Mission

Funding the fight for our oceans by supporting world changing no-profits.

Ocean. 5% Donated.

Every purchase supports ocean conservation, with 5% going directly to Blue Marine Foundation.

Fabric - 100% Airlume combed and ring-spun cotton.

Weight - Lightweight 4.2 oz/yd² (142 g/m²). Breathable for high-output activity; thin enough for technical layering under a shell.

Fit - Retail tailored. Designed for everyday.

Detail - Tear-away label to eliminate chafing during repetitive casting or paddling.

Ethics - Manufactured in the US via humane, no-sweat-shop protocols. Platinum WRAP certified. Fair Labor Association compliant.

We believe the most sustainable product is the one that lasts. We’ve moved away from "disposable" fashion by selecting a high-density knit that resists pilling and fading.

Water Reduction: Manufactured in facilities that use 7x less water than standard apparel plants, with a high-tech filtration system that ensures no toxins reach our waterways.

Solar Powered: Produced in Los Angeles-based facilities that are partially powered by renewable energy.

Zero-Waste Fulfillment: This product is Made-on-Demand via our US print partners. We only print what you order, eliminating the "deadstock" waste that currently fills 10% of global landfills.

Free shipping
On orders over $80 because we reward commitment to the cause.

Shipping times
Your gear enters the queue within 1 business day to save waste. We don't think bulk buying is good for the planet. So we made-to-order.

Transit
Once dispatched, USPS handles the final leg. Expect arrival within 2–5 business days.

Returns
If the garment is structurally unsound or the print is flawed, we issue a full refund. No probs.

You have 30 days from the date of purchase to report a malfunction.

Condition Items must be in original, unweathered condition—unused and unwashed.

Reach out to our team at support@northreef.store. We are here to help.

Regardless of a return, your 5% Mission Contribution remains deployed. We do not claw back funding intended for ocean protection.

Policy subject to change, but we'll always keep it reasonable.

How to Not Ruin Your New Favorite Shirt:

Cold water only (hot water is for overachievers)
Turn inside out before washing (protect that graphic you're gonna wear until it falls apart)
Use a gentle detergent - this garment-dyed cotton is chill, keep it that way
First wash might bleed a little, so separate it from your fancy stuff
Tumble dry low or hang dry (air drying = more time for snacks)

Drying Instructions:

Avoid High Heat: Air-drying is best to prevent shrinking and maintain the soft texture.
Tumble Dry Low (Optional): If using a dryer, select a low heat or delicate setting.
Remove Promptly: Take the shirt out of the dryer as soon as it's dry to prevent wrinkles.

Additional Tips:

Avoid using bleach or harsh detergents as they can fade the color.
Do not use fabric softeners, which may affect the shirt's texture.
If the shirt has a graphic print, avoid ironing directly on the design. Use a pressing cloth or turn the shirt inside out when ironing.

Reef Favorites

Every tee helps

We're committed to protecting the ocean we love. That's why we donate 5% from every order to charity—going beyond the standard 1% to create real impact for marine conservation.

Best sellers

For a better ocean

Power and purpose in every purchase. From the deep-sea seamounts to the surface-level drift, the pressure on marine biodiversity is relentless. We help fund policy change through through donating to charities.

Crafted to protect the playground

Our Tees are made from 100% combed and ring-spun cotton. By combing out the short, scratchy fibers before spinning, we’re left with a tight, ultra-smooth weave that holds up against the elements.

Frequently asked questions

Our goal is for every customer to be totally satisfied with their purchase. If this isn't the case, let us know and we'll do our best to work with you to make it right. See our Shpping and returns policy.

Definitely. Once your tee is on the way, you’ll get a confirmation email with a tracking number so you can keep an eye on its journey.

Cut for a relaxed, reliable fit that feels broken-in from day one. It’s a classic unisex cut that runs true to size—grab your usual for an effortless, everyday look or size up if you like a bit more room.
