Many of the new parachute systems come with options available at no extra cost.  Examples of this are:  limited colour selection and an aerobatic harness that keeps leg hardware from being pushing into your hips under higher negative G's.  Examples of other options available at extra cost are stripes, sheepskin padding for those long sweaty flights, ELT and oxygen pockets, lumbar support cushions, gravity retainer flap and quick releasing snaps.

Most new parachute systems are available in different colours, so if you need an olive drab container system to match the harness in your warbird, no problem.  If you need a red racing stripe on each side to compliment your hot rod, this can also be accomplished.  Custom monogramming is available from all manufacturers.  Some use confor foam (astronaut foam) for added comfort.
