Material Story

INNOVATION THROUGH MATERIAL CHOICE

The difference starts with the material.

At KAPSULE, every material choice has a purpose.

Our buoy fabric pairs an abrasion-resistant 210D polyester exterior with a PVC-free polyether TPU inner layer. Each layer has a role.

210D Polyester Exterior

The polyester provides structural strength, low water absorption, and shape stability.

Polyether TPU Inner Layer

The polyether TPU creates a waterproof, airtight barrier.

We chose polyether TPU for its resistance to hydrolysis and its flexibility at low temperatures—qualities that matter for gear made for open-water swimming.

Made for your passion for open water.

Thoughtfully chosen. Layer by layer.
