The not made of plastic stuff sack for muddy wet roads, rainy days, etc.  In VT where these bags are designed, we have as much rain as Seattle, but harder winters and more mud. So you know if we ride with this stuff out here, it’ll probably work for you, where ever ya live.  Stuff your sleeping bag in one, and your tent in the other.
