Designed for constant weight freediving:
The collar is made of lead coated with a comfortable layer of thermoplastic rubber. The main part weighs 910 grams and can be customized with five interchangeable lead weights on each side (40, 50, 60, 70, and 80 grams), allowing for a maximum total weight of approximately 1,630 grams, including metal components.
These weights can be easily replaced with lightweight plastic inserts, reducing the weight of the collar to as little as 1 kg. The variable weight system allows the collar to be adapted to different needs and the thickness of wetsuits used throughout the year.
The collar can be easily tightened, like the Dyno model, and the sides can be rotated for a better fit.
We left the weight distribution in the rear part so that, during the dive, the collar tilts towards the head, causing the two lateral “bars” to drop towards the clavicles and leaving the mouth and jaw area free for better management of the Mouth Fill.

Dynamic Design:
For dynamic disciplines that require greater weight, the base collar can be supplemented with additional weights, matching the type and weight of the segments used for deep diving.
The rear segments are secured using the same secure anchoring system as the Dyno model, allowing for a total weight of up to 5 kg while maintaining compact dimensions and comfort.

Tip: For those who need a collar weighing more than 4 kg, we recommend opting directly for the Dyno version.

The D&D collar is the ideal solution for freedivers looking for a high-performance product that can easily adapt to different disciplines and conditions, without compromising quality or reliability.
