Alchemy Silicone Neck Weight

The Alchemy Silicone Neck Weight is a purpose-built freediving weight designed to replace bulky belt weights with a streamlined, body-conforming alternative. Aerospace-grade silicone encapsulates the lead core, moulding the weight flush against your neck and shoulders so it stays in place throughout your dive — no shifting on the surface, no bouncing on descent.

Available in Black or White, the neck weight suits freedivers who train in depth disciplines where streamlining and weight distribution are critical, as well as pool athletes looking for a cleaner setup than a traditional weight belt.

Features

• Responsive Memory Architecture: Alchemy’s proprietary silicone construction conforms to your body shape on first contact and returns to position after removal — a consistent, custom-like fit every session.
• Aerospace-grade silicone: Medical-grade material resists degradation from chlorine and saltwater. Grips bare skin as well as smooth or nylon-lined wetsuits without slipping.
• Negative buoyancy rating: The stated weight figure is the negative buoyancy of each unit — actual scale weight is marginally higher. Choose the configuration that matches your suit thickness and personal buoyancy requirements.
• Made in Greece: Manufactured at Alchemy’s facility to consistent quality standards.
