Cooler by Nature

Nature is the ultimate designer.

At Coolcore, we help apparel brands harness the power of biomimicry to create their most advanced cooling products.

Building on 4.5 billion years of evolutionary R&D, our Biomimetic Fiber Geometry™ produces fabrics with exceptional softness, wicking, moisture transport, and evaporative cooling performance.

Biomimetic
Fiber Geometry™

In nature, fibers occur in a myriad of shapes. Silk is trilobal, cotton has a bean-shaped cross section, wool has a hollow core—each creating specific fabric properties. By contrast, almost all synthetic fibers have round cross sections, but only because they’re the simplest to produce. Coolcore harnesses the wisdom of nature’s own design to create synthetic fabrics with Biomimetic Fiber Geometry™ that enhances performance.
Coolcore’s patented technology enables us to form and spin differently shaped fibers to create yarns—and in turn fabrics—that accelerate moisture transport and evaporative cooling. These same techniques also enable us to engineer fabrics with enhanced softness, insulation, luster and strength.

Surface Area Improves Cooling

Shaped fibers have greater surface area than round fibers, accelerating evaporative cooling.

Channels Aid Wicking

Blending fiber geometries creates large channels to transport moisture away from the skin.

Low Volume is Lighter and Softer

Shaped fibers have less volume than round fibers, and more fibers per yarn in a given denier creates stronger, softer fabrics.

Improved Dye Uptake

Increased surface area improves dye uptake, creating more vibrant and longer-lasting colors.

Comfort. Performance. Safety.

Across product categories and user groups,
cooling technology is more than just a
nice-to-have: it’s a necessity.

An Athletic Advantage

In hot weather, competition is often as simple as survival of the coolest. Coolcore fabrics help keep athletes cool and comfortable when managing the temperature can be the difference between overheating and a personal best.

Triple-Digit Cooling Power

When being outside and in the sun is part of the job description, the cooling performance of our fabrics help keep hard-working crews cool and comfortable in triple-digit heat.

UPF 50+ Sun Protection

Coolcore fabrics offer excellent protection from the sun, with many rated UPF 50+. Coolcore’s sun protection won’t wash out, and works whether the fabric is wet or dry.

It’s not enough to follow nature’s blueprint—you must also measure the results. Coolcore conducts rigorous in-house testing against established ASTM and AATCC standards, and collaborates closely with Hohenstein —a globally recognized leader in textile research—to evaluate our fabrics’ performance and ensure they meet the highest standards of quality.
