Gravipack®

Innovative suspenders that reduce weight by 92% on the shoulders and back, to make you feel free and light in all areas! To do this, the idea was to put carbon inserts, the famous "Alpha N12 ribs", inside the shoulder straps giving them the shape of the thumbs to allow the load to be absorbed on other parts of the body. Gravipack is the only backpack in the world that no longer just rests on the shoulders. The backpack's center of gravity coincides with the center of gravity of the user's body. The neck and shoulders are relieved of 92% of the load and the feeling of weight is diluted. This is clearly a prevention against chronic low back pain, acute tendinitis and scoliosis. To validate its claims, Gravipack, which sees itself becoming a public health standard, commissioned new scientific studies. The Army and the Legion tested it for six months in real conditions. The army, under the spell, made him obtain the approval of the Ministry of Defense. After approximately 400,000 euros in fundraising, numerous patents filed and a medical study (bio-mechanics and movement analysis), production was launched. The Gravipack x KissKissBankBank 2020 crowdfunding campaign was a real success. We have reached 1437% of the initial objective!
