How long does a paraglider last?
General wear and tear (especially the latter) and deterioration from exposure to ultra-violet usually limit the useful lifetime of a canopy to somewhere in the region of four years. This obviously depends strongly on use. More commonly, paraglider life is measured in (flight) hours, with 200-300 hours being typical.
Generally four years of average use. This obviously depends on how and where it is used. Ultraviolet rays from the sun and physical abrasion on harsh terrain are the greatest source of canopy deterioration. 300-500 hours of exposure to UV is considered the normal life, depending on the quality of materials being used. Canopies are routinely tested for strength. Long before they become unsafe their flying performance will typically mark the need for replacement.
