More Details

Dimension is significantly superior to the standards in back inflation-style BCDs because of our high standards. This BCD features our Wrapture harness and SureLock II mechanical weight release systems. It is composed of a material called ResisteK that was specially engineered to withstand the worst conditions in saltwater or chlorinated water without fading or abrasion.

✔ Wrapture Harness System
The innovative Swivel Shoulder Buckles and Ultra-Thin Back Plate of the Wrapture Harness System offer unmatched comfort and keep the BCD from riding up on the surface. By keeping the cylinder close to your centre of gravity and shifting the weight to your hips, the device enables you to stand up straight when you are out of the water.

✔ SureLock II Weight Release
The SureLock II Mechanical Weight Release System allows for a secure, single-pull weight release.

✔ ResisteK Material
Looks good, and stays that way: made of new, technologically advanced ResisteK material to resist fading and abrasion in saltwater and chlorine.

✔ HP Hose Routings
Thanks to HP hose routings via the back, your system keeps a low profile, which reduces drag.

✔ Smooth, Flat Valves 
Proprietary flat valves further reduce drag

✔ Bladder Retraction System 
The bladder retraction system pulls in the sides of the bladder during deflation to keep you streamlined and reduce drag.

✔ Adjustable Chest Strap
A sliding adjustable chest strap can be lifted or lowered on a rail system for increased comfort. Aids in preventing drysuit valves.

✔ Additional Dump Option
Right shoulder pull

✔ Gear up! 
Multiple pockets, D-rings, and knife attachment points make stowing and accessing gear easy.

✔ Rolled Neck Collar
Comofortable rolled neck collar

✔ Non-Ditchable Weight Pockets
Located on the back of the BCD, these pockets help you achieve proper positioning in the water.

✔ Capacity
All sizes of the Dimension are capable of holding up to 30lbs/13.5kg of lead weight
