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’ve kept the weight distribution rearward so that, during the dive, the collar tilts toward the head, allowing the two side “bars” to descend toward the clavicles and leaving the mouth and jaw area free for better mouth fill management.
Freedivers starting with the basic collar can subsequently purchase the 4-segment set to reach 3 kg, or choose the Dyno segments (available in 290 g or 1 kg versions) to further increase the total weight.
