Mind you, this isn’t the first time we’ve seen garb constructed to withstand vicious knife fights, and apparently a few Japanese streets are becoming just as frightening as some in London. Reportedly created to provide protection against stabbers following an “increasing number of malicious crimes that have victimized children and late-night convenience store clerks,” Nihon Uni has developed a t-shirt crafted from “ultrahigh molecular weight polyethylene fiber.” Aside from rendering blades useless, the material is also completely machine washable and lightweight; still, the fabric can be penetrated by “sharp points,” so it’s up to you to steer clear of rooftop archers. Nevertheless, long-sleeved versions can be had this June for ¥22,000 ($221) to ¥59,000 ($593), while the way less protective short-sleeved variety will run you between ¥19,000 ($191) and ¥52,000 ($522).
