High SierraFairlead Drop Bottom Portable Polyester Duffel Travel Bag with Recessed Telescoping Handle, Mercury/Black, 34 Inch, 34 Inch

Q: will it fit in airplane carry on space?

Not really. If you pack it to the max then the top bulks up and it won’t fit. I was forced to check this back on multiple flights. A small hard case would be a better option if you want to carry on.

Q: How many liters does thus bag hold?

Hi Taylor. Well, I'm not going to try to fill it with water to answer the question. What I can tell you is this is the third High Sierra case I own. I have a larger and smaller. I really like this size, it fits everything I need to bring for a multi week trip. The only thing it's missing is the ability to become a back pack. Their larger one does have a zipper on the back that revels back pack straps. If this is important to you, check out their larger rolling bag.
