When it comes to perfecting the balance between comfort, performance, and coastal design, founder Holden Bierman sets a high standard. His go-to pieces are the swim trunks that define Coastal Cool—crafted from recycled plastic bottles and inspired by the coastlines that shaped the brand.

From Concept to Coast

Each pair of Coastal Cool swim trunks is designed with a purpose: effortless comfort, island-ready versatility, and sustainability that goes beyond trends. The fabric is made from 91 percent recycled polyester and 9 percent spandex, offering stretch, durability, and quick-drying comfort. Every purchase helps remove one pound of plastic from the environment through our sustainability promise.

Below are the five pairs our founder can’t stop talking about. Each one represents a different side of the Coastal Cool lifestyle.

Bora Bora Swim Trunks

Bora Bora Swim Trunks capture the energy of clear waters and bright days. With an island-inspired blue hue and breathable recycled fabric, they deliver a relaxed fit built for movement. Perfect for beach days, boat rides, and resort lounging, these trunks combine effortless comfort with signature Coastal Cool design.

Vacation Swim Trunks

The Vacation Swim Trunks are designed for travel and adventure. Lightweight, quick-drying, and refined, they transition easily from surf to shore. The tailored fit and four-way stretch make them a year-round essential for anyone chasing an endless summer.

Palm Ave Swim Trunks

Palm Ave Swim Trunks showcase a tropical pattern that embodies the heart of Coastal Cool. Inspired by the Carolina palms that line the beach, they pair vibrant design with recycled materials and UPF 50+ protection. This pair brings together performance and paradise in one classic fit.

Blossom Swim Trunks

The Blossom Swim Trunks bring subtle pastel tones into the lineup. Designed with a soft pink floral pattern, they reflect relaxed coastal charm. The breathable quick-dry material and elastic waistband make them ideal for long days in the sun or spontaneous getaways.

Tidewater Swim Trunks

Tidewater Swim Trunks blend neutral tones with an elevated coastal look. Holden often calls them “the most versatile pair in the collection” because they work just as well for an afternoon on the dock as they do paired with a cabana shirt for evening dinner by the water.

What Makes Them Different

Made from recycled plastic bottles for a smaller environmental footprint
UPF 50+ sun protection woven into every thread
Moisture-wicking, quick-dry technology
Lightweight four-way stretch for performance and comfort

From the Founder

“These trunks are more than just swimwear. They represent what Coastal Cool was built on—sustainability, simplicity, and style that brings people back to the coast.”
— Holden Bierman, Founder & CEO
