And I also notice that the gen strap - you almost can’t pull it too tight. Even tight, it feels comfortable enough that you don’t feel how tight it is. While the rep strap I have to leave loose. If I pull that one extra loop too tight I can really feel it while on the gen, snug or tight are both comfortable. If that makes sense.
I was able to compare a gen rubber strap with noob strap. You're right about being able to wear it tight without feeling like it's too tight. The noob strap would become constricting.
The gen strap also doesn't feel crappy when sweaty. I think it's because its rubber has a silky satin feeling when touching skin.
