No, I don't think they sell through REI. Check their site - www.golite.com. They do have great customer service and a lifetime warranty. They do have a 65L and a 80L. I have the 65L and like I said I don't have a lot of use out of it yet, but it's been great so far. I don't think they have a separate sleeping bag compartment, mine doesn't anyway. AND the price is hard to beat. My 65L was 100.00!! And FYI I just got some goretex rain pants from them for 60.00! Anyway check them out.
