The C&F Design Grand Slam Fly Box is a saltwater-ready case built around the C&F Universal System. Its wider, more robust slit-foam holds heavy salt flies securely, while the waterproof shell and strong closure protect contents from spray and sand. Designed to work in tandem with the Grand Slam Guide Boat Box, you can clip System Foam inserts in and out and move selections between boxes in seconds.
Modular system for flats-ready organisation
Choose from Bonefish, Permit or Tarpon layouts to match patterns and hook sizes. Swap inserts between this fly box, other System cases and your boat box without repacking. The result is a fast, tidy way to carry the right flies for South African estuaries and Indian Ocean flats.
