Great price for a set of 2!!! This is a supporter that can be used for the shoulder, waist, elbow, and knee, and can be used by both men and women. The items shipped will be new and unopened (^^) 【Icing and Warming Function】Based on feedback from customers who have used conventional shoulder supports, we have created a shoulder support that combines the functions of a cooling pack and a warmer. Because the gel is sewn into the shoulder support, it can be cooled by leaving it in the freezer for 1-2 hours, or heated by putting it in the microwave for 1-2 minutes. 【Cool Down Muscles】It can be worn after sports practice such as golf, tennis, baseball, and swimming, and the coldness lasts to cool down the muscles. It is especially effective in reducing the discomfort in the shoulder caused by repeated swinging motions, and can help you recover your condition the next day. Recommended for those who often exercise their shoulders. 【Simple Steps for Wearing】Step 1. Place the back of the shoulder support on your shoulder and tighten the lower part with Velcro. Step 2. Pass the long adjustment belt from under your arm and press the Velcro into the short belt. Step 3. Depending on your situation, if you feel it is loose, you can adjust the position of the two Velcro straps. *If you still feel it is loose even after adjusting the Velcro, adjust the position of the shoulder support. It is more effective to bring it closer to the upper arm than to the neck. 【Supervised by a Physical Therapist】This shoulder support was supervised by Mr. Yusuke Nakata, a physical therapist with 11 years of experience, who expanded the support area to further improve the stability and support of the shoulder support. 【Comfortable Rayon Material】Rayon material is gentle on the skin without irritation, so it feels good to the touch and is less likely to get stuffy even when you sweat, reducing stickiness from long hours of wear and providing a comfortable fit. The point of improving the cooling effect is also excellent. 【Strong Velcro】This latest upgraded shoulder support has also strengthened the Velcro. The Velcro of conventional shoulder supports is sparse and has weak tightening, but the reinforced Velcro has a larger area and density, and the tightening effect is even stronger, so you don't have to worry about it slipping. 【Universal for Left and Right, Free Size】It can be worn on both the left and right shoulders, and can accommodate shoulder circumferences up to 120cm and arm circumferences up to 37cm. You can adjust the fit to your body shape using the adjustment belt. It is a free size for both men and women.
