Fits under airline seats perfectly.

I've been a musician traveling for decades and needed something I could fit under the seat but had enough space for 3 or 4 days of cloths so I wouldn't have to check my instrument. This backpack worked out just fine. Fits under airline seats no sweat. It is comfortable to wear zipping through all those airports. Solid build. Looks good too.

Great backpack...durable for those "on the go"...I love the many compartments inside and outside most with zippers. You can feel secure knowing everything is in place. I highly recommend this product.
