Does it fit under the airplane seat?

Thank you for your interest in the Thule Aion Travel Backpack! When "comfortably" full, the backpack measures 11.02 x 11.81 x 18.5 inches. I suggest contacting your preferred airline to see if that matches their recommended specifications for carry-on or personal item sizes.

Can you attach/slide it on the handle of a roller bag for added convenience?

Yes. There’s a panel on the back that slips over the handle you pull the suitcase with.

Hi! The black pack has this "envelope" shape at the front like in the picture, or the same front "straight line" design as the nutria color?

Thank you for your question. The different colors of the 28L version of the Thule Aion backpack both have the "envelope" styling on the front of the bag. The "straight line" seam is present on all colors of the 40L version of the backpack. It appears there is an error in the images on the page. I notified Thule's Amazon team of the discrepancy.
