Panda™ is a single layer 2.0mm microfibre fabric. Unlike BumbleBee™, Panda™ doesn't not stretch or compress making the feel a little more rugged. Panda™ do, however, provide excellent grip on all types of bars and due to its robust structure, more protection.
Panda™ X-SF are the exception. X-SF "Soft Feel" is a material that offers both compression and elastic quality and is extremely soft. This model is great for natuaral dexterity and as a second skin when the hands are just too sore.
