Bought this bag last minute as I realized the bag I had wouldn't be big enough for our 12 day trip to Hawaii. Good thing because this bag was loaded by the time we returned home. It worked out perfectly. The fact that is expands makes it even more valuable. I didn't think I would use the expand feature but it worked out great. A bit heavy when it's so full but it was still under the 50 lbs and rolled with ease. Glad I made this purchase.
