"3 mm neoprene is 3 mm neoprene regardless of the name brand"......
That's like saying a ribeye is a ribeye. Of course, I don'tknow thatOrion has ever had "prime" .

oke
A premium stretch neoprene made for diving is quite a bit different than the hyperflex access suit or any of the low-midrange suits. You've gotta feel it to see the difference.
You don't have to have a premium suit for diving the local area, especially in the summer, but they sure are nice in the cooler months when a good snug fit with retained mobility is important.
