Tencent Digital (Compiler: Mi Ke) For those who often engage in confrontational movements, most of the sports injuries sometimes come from the impact of opponents, such as football, basketball, football and so on. If you accidentally get hit by your opponent, it will not only hurt, but it will also cause more damage to your body. Therefore, it is very necessary to choose an effective sports protection device. The BlindSave, which has just started to be crowdfunded on Kickstarter, is the world's first sports protection package that can be automatically adjusted to the body, taking into account protection and comfort. BlindSave is composed of two parts: sports vest and shorts. In the future, we will add various accessories such as knee pads and arm guards to protect many critical and important parts of our body. If you often suffer from an opponent's impact while playing basketball, then BlindSave can definitely provide you with the best protection, so you won't be “black and blue†after playing the ball. BlindSave uses a highly elastic protective foam to reduce and relieve vibrations caused by sports impact. This material has previously been used by the US military, so it can intelligently adjust the shape to adapt to changes and body shape of the human body. BlindSave can provide the most effective protection for ribs, thighs, buttocks, crotches, caudal vertebrae, etc. Even if it is impacted by an opponent, it can absorb the actual energy through energy absorption. Therefore, it will not only be painless, but it will not be affected. hurt. BlindSave takes full account of the ergonomic design and can be tailored to our body and does not interfere with movement and extensibility when worn. Its impact resistance is 20% better than competitors on the market, and it also uses 40% thinner filling. With a shock-absorbing foam of 2 to 5.5 cm, not only can it impact, but it can also immediately restore shape without deforming. What if you are also a basketball lover and you are often "black and blue" in the confrontation? Then try this BlindSave sports protection kit. Believing that with it, our reasonable collision with our opponents is more emboldened, and it will allow us to reach our own level. Currently, the BlindSave sports protection kit has started to be crowdfunded on Kickstarter with a crowdfunding target of US$30,000. The early bird price is US$55 (approximately RMB370), and if all goes well, it is expected to be released in December 2016. goods.
