The Alchemy silicone freediving neck weight is designed to help you dive deeper, faster, and safer. Simply push on its sides, and watch it form with incredible precision around your neck. So adjustable, it practically disappears. Conceived to take advantage of next-level performance, its unreal hydrodynamics will enable you to glide seamlessly through the water, providing superior stability for all freediving disciplines. Whether at the pool or at sea, it pushes what’s possible, bringing a new level of efficiency, simplicity, and convenience. When it comes to freediving gear, the less is the best.
Featuring our Responsive Memory Architecture, it provides mind-blowing comfort while it becomes an organic extension of your body that grips in place and follows your every move.
Utilizing aerospace-grade silicone and encapsulated lead, it is clearly tougher than any other neck weight of its class. The superiority of silicone, compared to common rubber, ensures stability, durability, and ease of use, while its sleek, innovative design guarantees that you’ll always stand out from the crowd.
Traditionally, freedivers and spearos wear a belt with weight around their waist to set their buoyancy as needed. However, when we freedive, we want to place the weights in the most efficient position on our body. Compared to the use of a weight belt, a neck weight has significant advantages. Why? The weight is below our lungs during the descent, pulling us down, and resulting in an effortless dive, especially while freefalling.
As the shape of the neck weight can be formed according to one’s needs, it will rest lightly on one’s jaw, without disturbing the mouthfill.
On a smooth skin, nylon, lycra, or super stretch wetsuit, the neck weight’s silicone sticks and won’t move around.
To determine the appropriate size for you, measure the circumference of your neck and choose the size that corresponds most closely to your measurement. If you plan to wear a wetsuit while diving, be sure to wear it when taking your measurements.
Lead time may vary from 1 to 5 working days, depending on our workload and stock levels.

Here's what they had to say about us.
Ideal neck weight – fully adjustable for a perfect fit!
There is a little hardness, but it looks beautiful! My husband and I love it in different colors. I often shoot videos underwater, but it's very stylish.
The logo was removed from the first neck weight produced, but this one has been improved! But I like the previous design.
I felt that the advantage of this product is that it is easy to wear and the design. But in some indoor pool, they said not to wear it because as easy to wear, it is easy to remove so if I drop it, the floor will break. And If I wear it a long time, my collarbone is pressed down and it hurts. Maybe the size issue. Overall, I'm satisfied with the product, so I'm thinking of repurchasing it later:)
It looks great and easy to use, but I feel the price is a little bit high. That's why even if I think about buying a new one, I end up using a handmade one. Thank you ????
I love the fact that the neck weight is easy to put on and remove. However, I have a small neck circumference, I just wish we had heavier-weight options. Upgrading to a heavier but longer neck weight would not do me any good since it would be loose when put on.
It's my favorite piece of equipment which I totally recommend to everyone. I thought it was unbreakable but last week the neck weight cracked and unfortunately it's not possible to use it anymore. However, I am planning to get another one because for deep diving it is the most comfortable weight.
I love the product, it fits perfectly and is good for line and pool training. Will definitely recommend this to others.
This is a really good neck weight as it is true to its measurement and weight and the material is high quality. Also, what I love about it is it doesn’t make you feel choked especially when doing line training/depth. Some neck weights put pressure on my Adam’s apple making me uncomfortable underwater. It is also slick in design, simple, yet cool to wear. It would be nice to have some more colors for aesthetic feels. Overall, I would always go with Alchemy as it ensures top design quality.
The majority of us changed from traditional neck weight (from tire tube) to Alchemy neck weight. From there on, we never looked back. The neck weight is very convenient during dives. It gives you less of that choking feeling since it is malleable and doesn’t interfere with our dives. You wouldn’t even realize you have neck weight till you finish the session, is amazing.
