• SOFT AGAINST YOUR SKIN, DESIGNED FOR EVERYDAY COMFORT: Our EcoShield liner is made using Oeko-Tex fabric (certified by the manufacturer) & combines bamboo lyocell with silver fibre in a thin, breathable fabric that sits discreetly inside a classic 100% cotton baseball cap. Lightweight, breathable, and designed to look and feel like a normal everyday cap. An eco-friendly choice designed with comfort in mind.

  • INDEPENDENTLY LAB-TESTED & HOW TO VERIFY YOURSELF: The EcoShield fabric has been evaluated across a frequency range of 30MHz to 10GHz, including testing in the US using IEEE 299 methodologies. Results recorded attenuation levels as high as 99.99 percent within the measured range, with peak attenuation 78 dB. For those wishing to conduct their own testing, a quality meter is needed. Please note-cell phones are not a reliable way to test. If your cell still rings it doesn't mean it isn't working.

  • CREATED BY AN AUSTRALIAN FAMILY BUSINESS WITH CERTIFIED EXPERTISE: Golden Kocoon was founded by Jenny and Dave, a certified E.M.F Technician with Building Biology training. From fabric sourcing and independent testing through to product design, every decision is guided by real-world experience, transparency, and attention to detail. As a small Australian family business, we're committed to creating thoughtfully designed products and providing genuine customer care every step of the way.

  • DISCREET SILVER LINER- LOOKS LIKE A NORMAL CAP: The EcoShield liner sits discreetly inside the cap, with no visible metallic fibres on display. The liner is intentionally flipped so the soft bamboo lyocell side rests against your skin, while the silver side remains hidden inside the cap- no drawing attention to your wellness choices. The adjustable hook-and-loop closure provides a comfortable fit for most adults and older children. The liner extends around the full crown and down the ear.

  • COMFORTABLE FOR WORK, TRAVEL AND EVERYDAY WEAR: Whether you're in the office, on a plane, commuting, or simply going about your day, this cap is designed to fit naturally into your routine. Hand wash recommended. If machine washed, use a gentle cold cycle and air dry away from direct sunlight. Available in Black and Grey. As a small Australian family business, we're proud to stand behind every product we make and are always here to help if you need us.
