Portable: The roll-up, insulated fish bag was a great invention when it hit the scene in the 1990s. Roll-up bags are currently offered by Canyon, Boone, Reliable, Smith and others. I purchased a Canyon medium boat bag (30 inches high by 65 inches wide) in 1999 that I still use today. For this season, I downsized to a Canyon Striper bag (30 inches high by 54 inches long) that tucks away neatly in my EdgeWater 228CC's head area and is eminently portable when chartering trips on other anglers' boats. Most of these roll-up fish bags feature ½- or ¾-inch closed-cell foam insulation on either side, easy-cleanup neoprene inner and outer skins, heavy-duty zippers, convenient carry handles and straps on each end, plus handy drain plugs. Portable fish bags don't have the extreme R-insulation value of big-box coolers, but when you don't need them, they are out of sight and out from underfoot in the cockpit.
