Putting on and adjusting this figure8 upper back brace is simple to do without assistance. For the first few days, limit yourself to wearing the support harness for an hour at a time. Expect some soreness as your muscles and ligaments relearn correct positioning. Once you've gotten used to it, you can wear it under and over your tshirt, under jackets and coats, sitting at your desk, at the gym, commuting to work, and even relaxing at home. 3.INSTRUCTIONS FOR USE PLEASE USE THE SIZING GUIDE Connect the straps to make a loose fitting figure 8 and slip your arms through the loops as if putting on a backpack. Position the crossover point at the middle of your upper back, just below the shoulder blades. Tighten the straps until they feel snug, gently pulling your shoulders back without restricting movement. Secure the straps. Begin by wearing the corrector for short periods, gradually increasing the duration as your posture improves. 4.COPPER INFUSED FIBERS. The copper infused fabric is designed to wick away sweat, keeping your skin dry and cool. The infusion also means the copper won't just wash away and will continue to function for the life of the product. Copper also encourages a gentle warmth that will help loosen up muscles, encourage relaxation and ease pain, soreness and tension.
