Loosen the mounts assembled on the brace, rotate 180°, and tighten. 2 sizes built into one mount allows simplistic design to become even more user friendly New optional snap-on strap clips create a free moving, fool proof way to secure the supplied shoulder straps and are completely removable for users who do not wish to use the shoulder strap system. In the event of an impact, these unique strap clips will rotate out of the way to help prevent further injury that static clips can cause New chest strap system offers more adjustment and simplified operation, included with each brace Lower the Atlas Brace on/off over your head like a helmet. No flimsy clips or fasteners to hassle with, and no disassembly of the brace is required during regular use Reversible rear mounts offer multiple offsets for length (chest size), and optional shoulder padding for height (neck length) are both adjustable right out of the box to create a custom fit for nearly every individual Dual pivoting back support provides greater surface area spread across the back, while transferring loads around the spine rather than directly into it. Increasing surface area helps disperse loads over a larger part of the body, to reduce pressure points in critical areas of the body Open sternum area helps transfer the impact around the sternum on a greater surface area of the body, possibly reducing the risk of fracture Unique, flexible, leaf spring design chest supports that allow the chest supports to aid in absorbing and slowing down Hyper-Flexion impacts. This promotes further rotation of the helmet, helping to keep the body in motion rather than the head coming to an abrupt stop on impact. This innovative suspension system can also help to reduce some forces transferred through the helmet, head and chest by distributing them through the brace Custom energy absorbing padding has unique material properties to help disperse energy from an impact before it reaches the body, further reducing smaller injuries such as bruising or muscle fatigue when compared to conventional EVA foams.
