Parachutes are cool and stylish, along with both men and women, including children. Plus, they are less similar to Jetpacks from Sims 3: Into the Future.
When it is in your sim's inventory, he or she can descend onto any lot when moving to another world or leaving a job as Secret Agent. If a lot has a tree, the wearer gets stuck by it. He or she may unstrap himself/herself from his/her harness, but they have to retrieve his or her parachute back before someone in public might have the opportunity to get it and as they say, "Finders keepers." It also have interesting interactions with sims: it could act as a blanket/bed, a "woohoo" location, kiting, and other actions.
Here's a weird fun fact: Did you know that kids under 13 or 18 years of age uses parachutes for some occasions in Fiction? It sounds unusual but I think children will get use to it in this game.
There are three varieties of rigs: one has a round canopy made back in 70 years (also different in seat type or backpack), another one is ram-air; a rectangular canopy which has 5 to 9 cells currently in modern times. Three of these containers have same mechanics, like cutaway, sliders, and steering toggles, but they were different models from 1920s to present day.
You can customize your rig just like you did in Create a Sim. It is fun to color the straps, canopies, handles, and containers for your sims, and modify your characters' rig with reserve parachutes, improved steering, and other modifications to assemble.
Since they have a skydiving simulator only in Sims: Superstar and skydiving center from Ford Focus Set in Sims 3, I assume that parachutes are supposed to be added in the base game updates or Game Pack or part of the Expansion Pack.
