Its about 5in drain type PVC, not as thick as the indoor stuff, I have real dense target foam in the bottom of it and most of the quiver is lined with Mossy Oak polar fleece! It can hold as many a 12 arrows with points, maybe 8 w blunts, judos etc! The foam allows me to also shove my hunting arrows with broadheads in the bottom into the foam, it holds them tight, quiver makes very little noise!
