Are you ready to travel? Consider this bag, which stores easily into a small cube and expands as you need it. -Dimensions: 16"x15"x 6.7" and expands to 21"x15"x 6.7", weighs only 3.85 lbs! -Folds into a 15"x9"x 4" pouch for easy storage -Durable and water resistant nylon fabric -Rear trolley sleeve, allows you to slide the bag over the trolley handle of a suitcase - 4 multi-directional spinner wheels - 3 exterior zippered pockets, and two interior mesh zippered pockets The carry-on can be wheeled or carried using its adjustable cushioned shoulder strap. I used this once for a flight but need to carry laptop & equipment and the soft exterior was not appropriate. I recommend for under-seat or check in luggage. I also used it 1-2 x for overnight stays and it worked well. Mint condition.
