Glow-in-the-dark five part patch kit for creating various markings for identification in low light conditions. These are made using a pretty high quality photoluminescent material, the same stuff that we have been using in various military applications for a few decades. This stuff is fairly effective and has a very long service life. We checked out some 10+ years old material we had in stock, it performed with roughly 90% the same efficiency as its brand new counterpart. Since the material itself has a very long service life we decided to not just rely on lamination/gluing to keep the photoluminescent material attached to the hook tape. Thus these are also sewn to give them the longest possible service life. This adds significantly to the manufacturing costs, but now we can be sure these won’t delaminate after a few winter/summer cycles of use.
