This is the 5th Wenger Laptop Backpack I've owned and I keep coming back to them. I travel A LOT! and these slide under the seat easily but still hold a ton of stuff. I subscribe to the "Carry everything I might need" theory and the pack in well organized and well built. The only reason it's a 4 star instead of a 5 start is that the pack is rated for a 17" laptop. My Lenovo Thinkpad P71 BARELY fits and the padding is limited around the top of the pack. After 4 years I did need to replace the pack because the main computer compartment zipper ultimately failed from the stress of the top corners of the laptop pushing on the zipper. Even with that it's the only backpack I've found that actually holds the laptop.
