Sean, My (most, all?) Security chute does not have a chest trap. There are only two straps that come from the seat and loop through on one side and snap to the opposite side.

That's an Aerobatic chute harness - designed to keep the hardware away from the lab belt during negative Gs. I have the same setup on my Long Softie (and had it on the Security I had before)- I like it better than the normal chest + leg straps as it gets the hardware up and out of the way.

Most chutes use the classic chest strap and separate leg straps.
