NEXTRAVELER TOOLS Sacoche This is not a store. This is a sacoche I obtained through a reader review. I used it occasionally for about a year to carry things like a MacBook. There is no significant deterioration of the Dyneema material. However, please understand that this is a used item before purchasing. Please refrain from purchasing if you are concerned about minor scratches. Product Description: NEXTRAVELER TOOLS Sacoche for MacBook Originally, a sacoche was designed for cyclists in road races to quickly grab supplies like drinks. However, we developed this sacoche with the aim of integrating your MacBook or iPad with your body, just like your iPhone, allowing you to carry them close to you, whether inside or outside your outerwear, creating a "man-machine integration." The material is made entirely of "ultra-high molecular weight polyethylene fiber (UHMW-PE)," a super fiber known for its use in explosion-proof sheets and bulletproof vests. This achieves twice the strength at half the weight of similar-sized products. It has higher impact resistance than polycarbonate and boasts eight times the strength of piano wire.
