What's an 88 GPA?

Now when one sees 88 gpa, what does one see? A high school grading system? Well, aside from the fact that 88 gpas don't exist, said numbers refer to a cool bag.

See, when you cart around musical equipment, most of them are not meant for outside. Or, at best are to be handled with care which usually means 'don't leave them to the elements and sudden drops'. Well, this bag in case is for speaker stands, you know the things that hoist speaks off the floor. But the bag isn't just for one, but for two of the things (as must people play with dual speakers) doubling its efficiency.
