MICHAEL H Hi Ryan, The crotch strap is designed to be laced through a back plate. The front will lace through the waist strap but you will need some way to secure the crotch strap to the back of the Excursion 2 BC. I don't have a diagram of the back of the Excursion 2 so I can't say if there is a way to secure the crotch strap back there.

NEIL J You need to ask someone who owns an Excursion 2. You need a hard attachment point at the bottom center of the bcd backpack, like a 1" slot. The front will attach marginally to the strap in front of the cumberbund. Not the ideal setup. Obviously, a backplate, harness & wings or sidemount bcd is better for scootering (clipped in). The real question is what are you using the crotch strap for?

EVGENY Z The croch strap is one size fit all it is ajustible , the wide is up to personal prefernces 1',1.5" or 2' all of them are strong enough to do the job ! I bought the 1.5" and works good for me !

JULIAN B All can be adjusted for height, so any will work. The width is the difference and that is just a personal preference. I liked the 1.5 inch one, and I still have it on my Hollis Elite II harness.
