I’ll confess that I do – ZPacks makes some and I just bought a couple from someone else who makes them with a reinforced end for the pointy end of the stakes (or steaks, depending on your locale – Sorry – I couldn’t resist). I have a stake bag with the proper number of stakes plus one with each of my shelters.
In what I thought was a flash of brilliance, I had Lawson attach a stake bag to the outside of the stuff sack that I got with my hammock tarp. It was really nice – but the bag was so small that I couldn’t get the tarp back into it after I put the lines on it!
