Sorry I missed this thread somehow... The Burrow is not designed to be reversible. However...their is less differential built in as the bags temperature rating gets warmer. There is some differential cut in the Summer Burrow but is not much and if you wanted to turn it inside out and use the reverse color it would more than likely still be just fine.
How do you know which color should be on the outside? Well, if you ordered a black, that would be the outside color, and the same with green (assuming WE did not get the order backwards here in Ohio.. ) Another way to tell is to look at the draw cord channels. We always use the the inner shell color to create the draw cord channels.
mostly about how they hog the passing lane on interstates.
But we never consider you guys "backwards"!
Lookin' forward to my new TQ!
