Superesse Straps has a line of EDC Hanks (handkerchiefs) that are designed to “assist in firecrafting, defense from an EMP, escaping illegal restraints, sawing, purifying water, filtering toxic air, and more.” The EDC Hanks are primarily handcrafted in North Carolina, from 100% cotton, along with aramid thread, Kevlar material, nickel/copper EMF cloth, Velcro, ripstop, and other materials. Superesse Straps offers several specialized handkerchiefs under the EDC Hanks line, including a burn-proof camp rag, a hank with a Velcro storage compartment, and a shemagh with a built-in utility saw.
