Re: [biker117] Lifespan of a harness + container
A harness and container will almost last forever. The worst thing that jumpers generally do is leave their rigs in the trunk of a car on a hot day. Temperatures over 200 F will degrade nylon strength if given enough time.
Otherwise inspect grommets for wear and replace Velcro when its no longer providing good adhesion.Keep it reasonably clean a fresh water rinse when it gets dirty, avoid harsh detergents.
Canopies can be subject to mildew damage if left a packed condition when wet.
Here is an old Australian mil study on nylon degradation with storage temperatures to 120 F.

The reason why I say harness and containers can last almost forever is that the breaking strength of a harness in in the tons and containers are really not subject to much loads whatsoever.
