BOPaiBusiness Smart 15.6 Inch Laptop Backpack Convertible Expandable Anti-Theft USB Charging Multi-Functional Travel Professional Work Office Men Commuter Large Black With Bottle Holder Waterproof

Good Travel or Work Bookbag!

I just purchased the Bopai Intelligent Increase Backpack and am very impressed by how well thought out the design is, the styling, and perceived quality for the price. As context, I am a professional consultant that travels often but am not an extreme road warrior anymore, and I sought a solution that would be highly functional, fit for use, and professional looking.First, the design is very well thought out, and if you have seen Bopai's video on this, you should take a look because it really does cover the bases. In terms of my standard professional setup, I carry a Lenovo Carbon X1 laptop, a iPad for note taking, an over the ear headset that folds somewhat flat (~1.5"), backup powerpack (which can plug into the inside of the backpack and be accessible through a USB port on the outside of the backpack), power adapters, business cards, medicines, money, pens, travel wipes, light toiletries, etc. in the main inner compartment. I may also carry 1.5-2" of documents and papers in the secondary outer compartment. I use the backpack's secret compartment for my passport and sometimes other small critical items. I use the hideable outer pocket for my umbrella. I can fit this all into the backpack without engaging the expandable section of the backpack. While I haven't done it yet, I could easily expand the backpack to carry a Hydro Flask and light change of clothes. One strap of the backpack has a small card slot, which is convenient for putting a metro card, whether it is an Oyster Card for London or an Easy Card for Taipei. There are handles which allow the backpack to be carried from either the top or the side. The side one is clever in the sense that the normal straps of the backpack can actually be hidden completely away and the backpack can be carried sideways more like an attache case. I have not tested the waterproof or resistant characteristics of the backpack, but the ballistic nylon looks to be tight enough to repel and resist moderate rain. Hard to say about whether the zippers would resist a long, heavy downpour on top of the bag.Second, the backpack is quite stylish to my eyes and preserves its form when packed or unpacked (i.e., not completely an unstructured backpack). As context, I have a Tumi Narita attache (was $695 new), which is a slim bag that has a mixture of leather and ballistic nylon, and I use that attache when I go to more formal meetings. The styling on the Bopai really has quite a similar vibe to my Tumi Narita, and I would be very comfortable carrying this backpack into almost any professional setting. In the two pictures I’ve submitted, the Bopai backpack is on the left and the Tumi attache is on the right.Third, the price quality tradeoff seems to be good, provided that the backpack lasts at least 2 years, hopefully longer, say 5-8. My Tumi gear usually lasts 10 years +/-. I could see the Bopai gear lasting quite awhile too, but it is unknown at this point. A lot of people seem to have reported zipper issues in the past. I don't immediately see where zipper issues might occur, but it's these types of fine points (e.g., zipper points, stitch failure, strap tears) where gear can become unusable.At this point, I recommend the Bopai backpack if you are looking for a professional backpack and carry a moderate amount of stuff on a daily basis. I am not sure I would carry thick, heavy textbooks in this backpack, mostly because this backpack looks more professional than rugged.I'll update this post if I run into issues, but I could see myself becoming a longer-term Bopai proponent.

This bag is very durable and useful!

I took this back pack on a 3 day trip to Portugal, I was able to fit everything I needed. It does get a little heavy to be walking all day with it, the backpack empty is 3lb, so after you add a few things I was walking around with 9lb. The breathability in the summer in Europe was non existent. My whole back was sweaty and my shoulders at the end of the day were tired. But I think it has great padding. If they will get rid of the water bladder area, the backpack will have a lot more space. Keeping the backpack organize was great, it has enough compartment for everything you need while traveling, keeping your passport safe, it attached to my carry on. The water bottle area was large enough. The zippers seem very durable, I was in London as well and in a few places in England and I didn’t tested it in the rain this summer, but my only major complain is that it got extremely hot in my back. Everything else about this backpack is great.I use it on daily based for the office, they provide you with a cable and a little packing container that now I use for cables and is amazing to keep me organize. As a daily backpack for work is great, perfect for documents and laptop. I haven’t tested it in the winter, but I guess it will keep my back warm. I hope. It connected very well to my power bank battery from Anker. The looks are great. I also tested it traveling to NYC and again it got hot, but I was able to fit thing I needed for a 3 days weekend trip. I highly recommend to use packing cubes. The cubes plus this backpack makes you be on top of your game when packing light. As I said, is not a perfect backpack because the temperature it generates when walking around when fully pack while traveling, only for this reason is that I can’t give it a 5 stars. I will keep looking for that great backpack for trips, but for work is when is not fully loaded, is great and the overheating problem in the back doesn’t happen. So perfect for work and school.
