Question on bottle caps for aging beer

I haven’t bottled in couple of years, but am getting ready to bottle a RIS that has been bulk aging 10 months . I was told to get oxygen obsorbing caps. I had a friend pick them up for me and the guy at the store gave him oxygen barrier caps. Is there a difference between O2 barrier and O2 obsorbing caps?
I though all caps were oxygen barrier???

The caps are the same. Called ‘barrier’ or ‘absorbing’ they both work the same way.
Getting wet activates the coating under the crown. Quick dip in sanitizer then immediately on the bottle.
