I went the other way with the bag situation, I went bigger. I was using a 40L trunk bag on less then 5 day trips, longer ones I added a set of saddle bags. Come time to check in I had: trunk bags, saddle bags, handle bar bags, a helmet....... It was just a jack pot. This year I bought the Ski Doo 80L bag with the snow cover. It comes with a shoulder strap for ease of carrying and lots of room for clothes, footwear, tool kit, extra base layers, balaclavas and much more. All positives, however with this bag I am not able to carry a gas can, that is a negative to some. I just have to make sure I travel with guys with gas jugs!! LOL.
