I just got a grip bag a few weeks ago and LOVE IT!!!!!!!
Fits very comfortably and does everything I want.
Ease of use
Only hold 20 disc's
Lots of pockets and storage
Less fatigue at the end of the round (from wearing and picking up)
Holds my stool and umbrella
The rain fly is AWESOME!!!
Looks like a back pack and wears like one, so none of that lower back pressure
Lots of pencil holders
Oh and the life time warranty is nice too.
The Down Side:
only hold 20 disc's tops (...........that has helped my game
Pencils fall out of the holders by the drink holds
It's a pain to sew patches on, because it's make of kick ass materials
Hope this helps
