Foldable Gym Duffle Bag for Women & Men - Lightweight Travel Carry On Bag for Airplanes, Workouts & Sports (Yellow) - Perfect for Gym, Travel & Weekend Getaways

Works perfectly as a personal item on Spirit. Departing I had it less stuffed and it fit and Returning it was more stuffed and it fit. Not many other bags have the lower shoe compartment, a side mesh pocket, front zippered pocket for passport and phone, a waterproof pocket for 3oz liquids on the inside with varying handle/strap configurations and a loop to fit it over your rolling checked luggage as you walk. It is a little flimsy, but that's what makes it foldable and collapse down, plus it gets sturdier as you fill it. I wish the padding on the strap was thicker though. All in all a good purchase for the price even if it's a little flimsy.This bag is amazing! It was perfect for a last-minute trip through Frontier and Spirit. I will say I over-packed a bit which led to the bag having to be adjusted a bit to fit into the personal items box, but that was my fault. If you fold everything nicely and tightly, it slides right in! I was able to fit in 2 pairs of shoes, sandals, 5 days' worth of clothes, and personal hygiene items. I would say this is a great investment for someone who travels alone a lot for just a couple of days. I was able to board with no problem.We travelled to Hawaii. This product compresses into a compact case so you can pack it in your checked baggage. Why? Because you can fill it up with souvenirs on vacation and then use it as a carry on for the plane. This will save you from having to pay for an overweight bag or having to pay for a second checked bag. I should have bought two of these and will purchase on for my spouse before our next trip.This did not pass personal item for American Airline or Spirit. I didn't even overly stuff the bag and didn't put anything in the outside compartment. As you can see on picture, I even have plenty breathing room. This cost me lots of money because it didn't fit. EXTREMELY DISAPPOINTEDI cannot comment on the water resistance because I did not get it wet, But these worked perfectly for clothes and shoes for one week down the shore on Spirit Airlines as a personal item. I was able to fit a ton of stuff especially clothes with a vacuum pack bag.I purchased this in a hurry before a flight and regret it. I wish I had ordered with enough time before my flight to find something else. It has held up okay as a personal item (only 50-75% full) but isn't comfortable and not that functional. The shoulder strap is cheap material, almost plasticy and painful after some time. It might work ok as a small, general weekend bag but I wish it had more pockets.It was durable for the airport and held atleast 6 outfits 3 sandals and toiletries. It passed Frontiers test of personal item bag so it was great.It is perfectly fits Spirit airline standard
