hmmm, looking online and finding some 20 to 25 gallon airtight totes here and here

Not sure if one of those would be big enough to hold all three 0 degree mummy bags loosely. I also saw a 50 gallon tote here and wondering if i'd be almost as well off sealing the sleeping bags loosely inside a garbage bag before placing them in the 50 gallon tote? Any thoughts on this?
