Fishpond hired a bison to step on these and he sprained a hoof. Our reels came through unscathed. Ok…we may be stretching the truth a little, but you get the idea. The Kodiak reel case is serious protection for your coveted hardware, available in three sizes to accommodate a wide variety of reels. Sizes: Small 3.5″ diameter for 2-5 weight reels. Medium 4″ diameter for 4-8 weight reels. Large 4.5″ diameter for 8-12 weight reels. Please specify.
