Here is the breakdown of all the Glute Bands as each one is both a different print + different resistance:
Glute Band 2.0: Medium band. Light resistance.
Glute Band 3.0: This band is smaller than the Glute Band 2.0. Medium band. Medium resistance.
I use both bands and use them on different leg days and or with different/certain exercises. For example, Glute Band 2.0 I use for warming up prior to my leg days and I add when I do bodyweight exercises. The Glute Band 3.0 I use and add to majority of my exercise to make it that much more challenging and to be able to activate my glutes more in certain exercises (perfect example would be hip thrusts)
Both Glute Bands are anti-slip that have grips on the interior side of the band to prevent from the band to slide and roll up. So no need to worry about the band slipping off and your booty gains going anywhere, because they wont be going anywhere, they'll just get bigger from here on out so stay ready (;
