Review: Perfect Work/Travel Backpack - Perfect work/travel backpack that has an elevated look. Love the minimalist design, quality metal zippers, and the side pocket that zips up to keep a clean look when not using it. Very functional with a separate laptop storage area and back strap to secure it to a rolling luggage handle too. Only con is the leather is fairly thin and I’m not sure how it will hold up long term, but it’s been very durable thus far and it’s tough to expect full grain leather at this price point. Very satisfied overall.
Review: Purchased Bopai as an alternative to Tumi - 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.

## Questions & Answers

**Q: does this bag come with a warranty?**
A: This bag does not have a warranty but they go by the Amazon’s three month return policy. I received a new bag because of the fact that the design of the zipper latch can cause an issue because it’s not closed. Be advised if they do give you a new one it may not be the same thing as the original. The new bag they sent did not come with an inside laptop strap as my original one did.

**Q: How much does the bag weigh?**
A: Dear customer
This backpack weighs 3.2 LBS.

**Q: Does anyone know if this fits the new macbook pro 16" ??? this bag is perfect but i need to make sure my laptop will fit!**
A: Dear 
It's OK. The Macbook pro 16'' is a super slim laptop. This model Backpack can hold it. Thanks for your understanding and supporting.
----Bopai Online

**Q: Just to be sure, the charger pack is detachable for in-plane travel as seems to be required ny more airlines???**
A: There is no charger pack included with the bag.  There is a usb cable that can plug into your battery- the other end is connected to the USB port sewn onto the bag and it is not removable.

### ⭐⭐⭐⭐⭐ I have one. Just bought one for 50th birthday of a friend
*by G***O on May 8, 2024*

This is a superior bag for work, if you don't want to look like a backpacker (even a cool backpacker). It can double as a briefcase if you fold back and secure the shoulder straps. It has a handle on the top and on the side, so it doubles as a carry backpack or a briefcase. The comfortable shoulder straps for one side or both. The laptop's nice smooth fabric compartment can hold my 16" and that main pocket expands to store all electronics and personal items. I like the zippered compartment in that section to store a passport and wallet. The other two compartments are fine to keep items organized, or for a book or an iPad. The zippers work well, but the second one I ordered had a defective zipper lining on the second biggest pocket and that made it difficult to zip open or close. I sent that one back and got a replacement within two days even before they received the returned one. I looked at and checked out many (like 50) backpacks but this one is by far the best -- certainly the best for the price (yes there are fancy ones for $450). I am a bit glad that this bag is not that popular, as it still catches folks eyes as something very stylishly different than what most folks have.
