#36 Tarred Twisted Nylon Bank Line

Traditional bushcrafters, trappers, and field guides often swap out standard 550 paracord for #36 tarred twisted nylon bank line for good reason. Manufactured from high-tensile nylon filaments treated with an asphalt-based tar emulsion, this utilitarian cordage prioritizes sheer environmental resistance and knot security over plush hand-feel. It is engineered to sit underwater or endure harsh UV exposure for months without rotting, stretching excessively, or losing its structural integrity.

In practical field use, the tarred coating creates a tacky surface that bites firmly into itself, ensuring hitches like the taut-line, prusik, and clove hitch hold reliably without creeping loose in high winds. The treatment also keeps the nylon from soaking up water, preventing the dreaded frozen-stiff cordage problem in sub-freezing conditions. Because it utilizes a twisted rather than braided construction, individual strands can be easily unlaid for smaller tasks like snare triggers, lashings, or gear repairs, though raw cut ends will unravel instantly if not quickly melted with a flame.

Compared to 550 paracord, bank line yields similar working utility at roughly half the bulk on a spool, packing down tight into pockets and small kit pouches. The trade-offs are tactile: the tar leaves a faint petroleum scent and a slight residue on bare hands during prolonged knot tying, and heavily loaded knots can be stubborn to untie. For permanent camp setups, trotlines, and durable tarp tie-outs where set-and-forget reliability matters most, it remains an unbeatable value.
