Timeless Style | Made to Last

When you live by the water, you learn the art of layering. The mornings are foggy, the afternoons often sunny, but the wind can carry a chill just when you least expect it. That’s where the Ocean SF midlayer comes in — the quiet hero of any wardrobe, bridging the gap between performance and ease.

Ocean SF creates clothing that bridges the gap between technical performance and everyday elegance. Designed for those who move between sea and city, our pieces honor craftsmanship, sustainability, and the quiet confidence of coastal living.

Intelligent Warmth

A great midlayer should keep you warm without weighing you down. Ours are designed with that principle at heart — lightweight, breathable, and flexible enough to move with you. Whether layered beneath a shell or worn on their own, they regulate temperature naturally, adapting to your body and the elements around you.

Crafted from Premium Materials

Every Ocean SF midlayer begins with carefully chosen fabrics — from soft merino wool blends to technical, recycled fibers that wick moisture, resist odor, and hold their shape. The result is a garment that feels incredible against the skin and performs beautifully, season after season.

Designed to Move

Inspired by life on the water, each piece is cut for motion. Ergonomic seams, tailored silhouettes, and clean construction ensure comfort in every moment — whether you’re hauling lines, hiking a coastal trail, or heading into the city.

Effortless Versatility

We believe function and style should never be separate. Ocean SF midlayers move easily from sea to street, pairing just as well with denim as with deck pants. Their minimalist design and coastal color palette evoke the San Francisco waterfront — understated, elegant, and enduring.

Sustainability with Intention

At Ocean SF, we build garments meant to last — pieces you’ll reach for again and again. Durability is a form of sustainability, and we’re committed to reducing waste through timeless design, quality materials, and responsible production. Every midlayer reflects that purpose and care.

A Layer for Every Moment

From dawn sails to twilight walks, our midlayers are designed for real life — the kind lived between land and sea, where comfort, beauty, and performance meet.

Ocean SF and Rolex Big Boat Series

Ocean SF is the Sustainability Partner for the Rolex Big Boat Series. Here is an outline of the races this weekend.

The boats will be docked around the bay at different yacht clubs. The first warning signal will be at 11:00 a.m., so you will see the boats waiting and ready for the race committee to do the countdown for their class.

In a typical sailing race, the race starts five minutes after the first warning signal. The standard starting procedure, called the “5-4-1-Go” sequence, is governed by the Racing Rules of Sailing (RRS). 

This sequence uses both flags and sound signals to communicate the countdown to the racers. 

  • 5 minutes (Warning Signal): The race committee raises the class flag for the boats that are about to start and sounds one short signal. The start line is now established, and racers begin their final preparations.
  • 4 minutes (Preparatory Signal): The committee raises the “P” flag (the Blue Peter) and sounds one short signal. Racers must now stay on the pre-start side of the line. In some races, other flags like the “U” or “Black” flag may be used to indicate stricter starting penalties.
  • 1 minute: The committee lowers the preparatory flag and sounds one long signal. This marks the final minute before the start.
  • 0 minutes (Start Signal): The committee lowers the class flag and sounds one short signal. The race has officially begun. 

All Classes:

Friday, September 10th – First Warning 11:00

Saturday, September 11th – First Warning 11:00

Sunday, September 12th – First Warning 11:00

In San Francisco, you can watch the races from Marina Green or Fort Mason. Come and join us!



Summer Internships

Summer Interns – Ocean SF

Seeking highly motivated and creative individuals to join our intern team. Ideal candidates must be interested in building a sustainable fashion brand and, most importantly, promoting environmental causes.

This program will teach and develop entrepreneurial skills on all levels, including product development, marketing, fashion design, social media advertising, technical skills, project management, and LEADERSHIP.

We currently have three returning interns from last summer and two new hires. Our interns are studying business, digital marketing, and environmental sciences at Berkeley, Duke, Santa Barbara, and SLO. So far, we have a great team, but we need students with web development and data analytics backgrounds to help out.

You can learn more by contacting me directly.

How Ocean SF Became A Leadership Incubator: 

Note from our founder:

My daughter Paris suggested turning Ocean SF into a leadership incubator because that’s the part of running Ocean SF that I love the most: turning people into great leaders.

There is nothing like allowing the interns to pull the levers and drive new business. It gives them immediate feedback on their efforts: number of likes, shares, and of course, sales.

Yes, social media looks easy, but it’s not. It takes creativity, careful planning, skill, and hard work—Ditto for creating new products, running a website, inventory control, and managing countless pop-ups.

Running a clothing company like Ocean SF can look glamorous, but it is anything but. It has been one of my greatest challenges.

Since 2021, Ocean SF has become more than a lifestyle clothing brand — it’s a leadership incubator that fosters creativity, resilience, and purpose-driven action. With a foundation rooted in sustainability and community impact, Ocean SF inspires individuals to lead with intention in their professional and personal lives. By exemplifying values like innovation, environmental stewardship, and ethical business practices, the brand creates a unique ecosystem where emerging leaders can learn how to align their actions with a greater vision. Each product and initiative reflects a commitment to leadership that blends style, functionality, and responsibility, empowering customers to make meaningful choices in their own lives.

The Ocean SF leadership incubator focuses on cultivating essential skills like adaptability, collaboration, and vision. Through workshops, events, and mentorship opportunities, the brand connects individuals who share a passion for environmental awareness and positive change. Participants not only learn how to lead but also how to inspire others to embrace sustainable practices and forward-thinking solutions. By fostering a culture of growth and shared responsibility, Ocean SF positions itself as a platform where leaders can thrive while addressing some of the most pressing challenges of our time.

At its core, Ocean SF is a movement that encourages individuals to lead by example. Whether through the garments they wear or the initiatives they support, the brand reminds its community that leadership starts with small, intentional actions. By creating opportunities for learning and collaboration, Ocean SF embodies the belief that leadership isn’t confined to boardrooms; it’s present in everyday choices and their impact on the world. In doing so, Ocean SF, besides producing high-quality, ethical clothing, nurtures a community of empowered leaders ready to drive change.

How Ocean SF Became a Leadership Incubator

In 2021, when I was struggling the most to get my company Ocean SF off the ground, my daughter Paris who was the Ocean SF summer intern project manager that summer suggested I make it a non-profit because it certainly was NOT profitable. I was personally funding Ocean SF and trying to sell clothes in the middle of a pandemic. She suggested turning Ocean SF into a leadership incubator because that’s the part of running Ocean SF that I love the most: turning people into great leaders.

Luckily, we are not a nonprofit and have grown more and more profitable over time, but working with my interns is one of my favorite things. I love getting to watch them pull the levers and drive new business. Yes, social media looks easy, but it’s not. It takes creativity, careful planning, skill, and hard work—Ditto for creating new products, running a website, inventory control, and managing countless pop-ups.

The Ocean SF journey proves that when we start on a course of action, especially one where we follow our hearts, we never know where we will end up. I feel blessed to have work that I love where I can provide real impact every day.

Thank you to all who have supported me along the way.

Love and blessings to all.
