My personal regs are always kept in a padded reg bag when not in use. I have about half a dozen other regs; back ups, rentals, loaners, you get the idea. I keep those loosely coiled in individual plastic storage bins. Keeps critters out and they stack neatly. A 12 to 15 quart bin will accomodate most regs nicely. Got mine at Wal Mart for $2 or $3 each.
