These are harnesses that are built by Crow Enterprises. These people make all kinds of restraint systems for all kinds of race cars and now airplanes. They carry some sort of certification but it is a cert for race car activities not aviation but if it is good enough for a 300mph dragster, it should be good enough for an experimental airplane.
If you order, you need to talk to Fred Crow as he knows about RV's and what you need to make them work in your plane. The stock models are not setup correctly so don't assume you can just order the standard ones off the internet.
Crow was super easy to work with and shipped my order the very next day.
What you will see here costed me $140 each set plus shipping.
Basically you can get a full 5 point harness with the cam lock latch for the same price as the Van's harness with the lift latch system and Van's does'nt come with pads.
These are on par with the Hooker harnesses just way, way less expensive.
What I ordered from them was the 2" Y style harness with pull down adjustement and 1/4" bolt in anchors and sewn in pads, 2" x 55" seatbelt with pull up adjustment and 1/4" bolt in anchors, cam lock latch and grey in color.
They ship these things packed well and in individual boxes. Total weight for the shipment is 9lbs including the boxes.
Here you can see the entire harness.

Here is the expensive part, the cam lock. This cam lock allows two positions. When rotated fully counterclockwise, it locks in the open position. If you partially turn it from close, all the latches unlock and the clips are free to fall out. When in the locking position, you can insert each clip one at a time and there is no need to insert all of them. One of them is permanently attached so the lock never comes completely free.

Here you can see how tall the Cam lock is which is a little concerning for us with extra Bubba factor. These may be hit by the stick we shall see. I guess they have to be tall enough for the guts to work inside. The camlock seems to be machined out of billet aluminum and black anodized. Looks like a good quality piece. I would not dare take it appart to see inside but I assume high quality inside as well.

Here is a nice shot of the logo sewn into the harness. It is not high contrast like some I have seen so it looks great. You can also see the high quality stitching

Here is the back of the pads. The pads are made of some high quality fabric that seems soft to the touch on the back so it should be comfy against the neck and not rub.

I elected for the Y style harness which is also adjustable on the common strap. They give you plenty of strap to work with so this will be easy to fit to my liking.

This is one of the seatbelt straps showing the pull up adjustment.
