dedicated saddlebag coolers (e.g., Reinsman, Equi-Lok) that attach to your saddle for trail rides, or larger canvas/neoprene totes (e.g., NGIL, Carhartt) with multi-compartment designs for general stable use, featuring separate insulated sections for drinks and pockets for other gear, often with equestrian themes. Key features to find include heavy-duty insulation (foam, aluminum foil), leak-proof linings (EVA), and practical elements like bottle openers or shoulder straps.
