The Waterproof, Sweatproof Alternative to Traditional Jewelry
For decades, jewelry has come with an unspoken list of restrictions:
- Take it off before swimming.
- Remove it before exercising.
- Avoid sunscreen, sweat, saltwater, and chlorine.
- Don't wear it in the shower.
- Store it carefully to prevent tarnishing.
For many people, traditional jewelry simply isn't designed for real life.
Performance Jewelry is different.
KADEN & KAI® created Performance Jewelry because we believe jewelry should be designed for real life—not protected from it.
Whether you're walking the beach, spending a day by the pool, exercising, traveling, or simply navigating a busy schedule, your jewelry should be as comfortable and resilient as the rest of your wardrobe.
The Challenges of Traditional Jewelry
It's just a fact. Most metal jewelry struggles with moisture, heat and chemicals.
Perspiration contains salts and minerals that can accelerate tarnishing, discoloration, and wear on many metals. During hot weather or physical activity, metal jewelry can feel heavy, sticky, or uncomfortable against the skin.
Ocean water is highly corrosive. Salt residue can dull finishes, accelerate oxidation, and leave jewelry looking worn long before its time.
Pool chemicals can be particularly harsh on jewelry. Chlorine exposure may contribute to discoloration, surface damage, and deterioration of certain metals and finishes.
Many consumers experience irritation from nickel and other metal alloys commonly found in jewelry. Heat, sweat, and moisture can make these reactions even worse.
The result? Many people remove their jewelry exactly when they want to be wearing it.
Why Performance Jewelry is A Great Alternative to Traditional Jewelry
Performance Jewelry is designed to perform in conditions that challenge traditional jewelry.
Every KADEN & KAI® piece is handcrafted from Verdasil®, our proprietary performance material engineered to withstand movement, moisture, and everyday wear while maintaining its beauty and comfort.
Not only is it ultra-lightweight, soft and flexible, it can withstand harsh environments that traditional jewelry can't. It is unaffected when exposed to harsh chemicals, oils, solvents and does not feel or hot or cold when exposed to extreme temperatures.
It is unaffected by sweat, moisture, chemicals, soaps and salt water.
Verdasil Performs Best When Traditional Jewelry Falls Short
Verdasil is:
- Waterproof
- Sweatproof
- Saltwater resistant
- Chlorine resistant
- Ultra-lightweight
- Flexible and comfortable
- Hypoallergenic
- Designed for all-day wear
Unlike traditional jewelry, Verdasil® won't tarnish, corrode, or leave green marks on your skin.
It simply keeps performing.
Not All Silicone Is Created Equal
Many inexpensive silicone products are manufactured using lower-grade materials designed for low-cost consumer goods. These materials may contain fillers, additives, or manufacturing shortcuts that prioritize cost over long-term performance.
At KADEN & KAI®, we took a different approach.
Our premium, FDA Grade silicone is produced in California by ElastaPro, a U.S. manufacturer known for supplying high-performance silicone solutions to demanding industries including food processing, medical, aerospace, and industrial applications.
Verdasil® is created with the same commitment to quality and performance.
The Verdasil® Advantage
The Verdasil® Advantage begins with performance.
Our material is engineered to maintain crisp lines and sculptural forms while remaining remarkably lightweight and comfortable. It will not become brittle or lose its shape under normal wear.
Verdasil® is fully compliant with FDA Title 21 CFR 177.2600 standards for repeated food-contact applications.
It is:
- 100% hypoallergenic
- Nickel-free
- Latex-free
- Toxin-free
- PFAS-free
- Safe for sensitive skin
For individuals who struggle with metal allergies, Verdasil® is an excellent alternative.
Quality Craftmanship and Performance
Proudly Made in the USA
Verdasil® is manufactured in California, and every KADEN & KAI® design is handcrafted and assembled in Massachusetts.

Proven Retail Performance

Customers consistently tell us the same thing:
- They bought the jewelry because it looked beautiful.
- They became loyal customers because of how comfortable it was to wear.
Jewelry Designed For Real Life
Life doesn't stop for sweat, sunscreen, rainstorms, pool days, beach vacations, workouts, or busy schedules.
Your jewelry shouldn't have to stop either.
Performance Jewelry is a new category built around the idea that style and function should work together. By combining bold design with high performing materials, KADEN & KAI® creates jewelry that looks striking, feels effortless, and performs wherever life takes you.
Because jewelry should be designed for everyday life—not protected from it.
