Wall City no longer makes disc golf bags.
My first bag was a Wall City circular bag from World's Biggest. Sold that one and got a cube. The cube and mega-cube bags are a quality product. I just needed a bit more storage room for my disc golf treasures.
I personally have the Baby Revolution bag. They are around $40.00 It holds 12-14 disc's , super durable , holds water bottles. Super Comfy with Quad Shocks. So lite with 12 discs , you would hardly notice your carring anything.
