All of the product literature states that this bag will hold 200 feet of 11 mm rope. This is true... But barely. I can put a 200' 11mm Sterling HTP rope in this if it is coiled tightly from the bottom up. There is no way to put anything else in this bag. Not a small tarp, no biners; nothing. Do not get this if you want to use it for PMI Pit Rope. It will be impossible to coil it tightly enough to fit in this bag. As for construction, the nylon is thicker than I anticipated and the build quality seems fairly decent. I'm keeping it. It holds my rope, but I just which it were a little bit bigger in diameter.
