Air Brace by Atlas Brace®. Each adult brace comes with Atlas Brace Hybrid strap - It combines the versatile function of the common elastic "X" straps, with the comfort of a chest strap. To wear the Hybrid Strap, put it on just like a t-shirt - 1st put each arm through one of the sides, then lift it up and put your head through the middle, making sure the thinner straps end up over top of your shoulders, and the thicker straps end up around your chest. Adjust all 4 straps to the desired length - It works best when the thicker straps around your chest are sitting flat, instead of pulling at an upward angle. You can wear the Hybrid strap over or under your jersey.
1st put on your brace, and test the fit. The chest, back, and shoulder padding should be resting snug against your body when adjusted correctly. Next, decide on a height setting that will provide you with a sufficient range of motion and eye sight while riding. You can opt to use, or not use, the supplied height spacers. After choosing a height preference, fine tune to fit your chest thickness. Each adult brace features Atlas Brace rear Smart Mounts. Smart mounts are reversible to make the brace fit a thicker chest, and they also feature 3 angle adjustments to help fine tune the fit. If the brace is too tight and not resting down flush on your shoulders, try reversing the position of the Smart Mounts. Certain body types may want to adjust the angle of each back support, and you can choose from -10, 0, or +10 degrees to make sure each back support sits flat against your upper back.
