I haven't seen one of these up close and personal but Smith Fly's new Cooler Kilt, launching in late November, makes sense to me. Especially in light of limited space in the boat, pickup truck, or campsite.
From their press release: By snapping directly to a cooler, the Cooler Kilt keeps gear consolidated, out of the way, and easily accessible. It was designed for people fishing on small watercraft, including stand up paddleboards, kayaks, and micro skiffs, as well as spin-and-bait casting fisherman and hunters.Many anglers keep coolers on board of their watercraft to carry water, lunch, snacks, and beverages. They also carry cumbersome bags that are intended for wading. SmithFly owner and fisherman Ethan Smith set out to design a product that easily enables people to attach their gear directly to the front of their coolers.
“There wasn’t a good solution for carrying fly boxes and tackle on the water while fishing from smaller, more nimble boats,” said Smith. “Now you can haul your gear and your beer in one trip from the truck to the boat. The Cooler Kilt lets you put your stuff right where you can access it, without any hassle.”
Cooler Kilts are made in the U.S.A. and will be available in five sizes accommodating cooler sizes from 25 to 65 quarts. They’re constructed of 1000D Cordura, and feature multiple rows of Mil-Spec nylon webbing with one-inch tactical bar tacks. The back of each kilt has snaps that attach to coolers. The snaps are available as stainless steel self-tapping screws similar to those of boat covers, or as pressure sensitive adhesive pads with snap heads.
