SDYSM Laptop Backpack 17.3 Inch TSA Friendly Travel Backpack for Men Women Waterproof Work College Business Bag with USB Charging Port Anti Theft Large Computer Carry On Backpack, Black

This pack just survived a month of travel and held up well. This was not hiking travel but plane, car and train travel. We had not issues with zippers, no rips, tears, etc. and it was stuffed full often and lugged around a lot. It still looks like new and will serve us well for a long time. I would recommend this backpack for students, work, or travel.

Perfect size to fit under the seat when flying as a personal carry on item. I really liked how I could plug my portable charger in the side. Great feature!

Used this for a weekend trip. It was a perfect size for a personal item on air plane

This backpack was large, just a bit too large for me.

This is a great bag! My husband is an over packer, but still was able to carry all he needed for a recent 2 day business trip! Lots of room and easy to carry!

Happy

How easy it was to place my CPAP in its case. Easy access for TSA. I has ample room for pair of sandles. The Tablet and Note book had plenty of room in the other main compartment. The only problem I had was remembering where I put everything.

Ive been using this for a few months and took it on an international flight. Has room for tech stuff and a change of clothes. Zippers all work well. I like it and will continue to use.

Love how much room there was. I had plenty of space fir more items in the bag.
