I'm an occasional backpacker which is how I ended up on this site, but I also travel on business 2 weeks of every month. This UL sleeve is PERFECT. I love how easily I can slide it in/out of my carry-on so I don't have a bulky laptop bag as yet another thing I'm carrying around. On the plane this bag can roll up and stuff in seatback pouch instead of being an annoyance in my footwell. At my destination this laptop sleeve is my daily around the office and I can usually find a way to creatively wrap and clip the strap around a conference room chair so my bag isn't a trip hazard on the floor/waste of space in meetings. After work if I want to go out without taking my laptop back to a hotel, this black bag is slim enough to slide/hide under a car seat in a rental so it's not a theft target for a break in. This sleek bag with extra zip pockets is more than just a sleeve, and the carry loops on BOTH sides plus the shoulder strap are versatile and all get used throughout my various modes of travel and use. I LOVE it. I will watch for sales so I can buy spares as the price is the only down side.
