I only use this a couple times a year, but it is amazing for flying with my backpacking pack. I have a 70L Osprey Aether pack and this bag is just big enough to handle my pack, my hiking boots, trekking poles, and some other loose items for checking them through the airport. Granted, carrying this while fully loaded is quite challenging, but what can you expect from a huge 45lb bag? I imagine if you need to lug hockey gear around or other bulky items, this would also be quite handy. Considering it is pretty inexpensive, I'm glad I picked this up.
