Make sure yours is freshly packed, at least once a year. Grit collects in the reserve parachute (causing damage through abrasion). Damp from ballast and wet grass can seep into the reserve (causing mildew and hampering opening time). The fabric gets compressed which delays opening. Packing elastics can perish, badly packed reserves can slide out of nappies, loops can tangle, and pins can get damaged. All materials degrade with age, even when not used.
Although you can repack one yourself following the manufacturer’s instructions, we recommend using a professional service to ensure it’s done right and that the canopy gets a thorough inspection on a light table (at least every 2 years). Steerable reserves are more complicated to pack. We don’t offer a reserve repacking service for types of reserves- round, square and steerable(Rogallo).
