This one is bad. *by M***E on January 25, 2020* This is a well-designed bag with great convertible features. Unfortunately a bag like this is only as good as its zippers. I ordered and returned one of these bags for a direct replacement because it had a defective zipper that came apart without any load on it at all. The replacement was no better. It has the same problem. This could be a good bag if the zippers actually worked. ### ⭐⭐⭐⭐⭐ Amazing case for one bag travel *by C***W on March 10, 2019* I was looking for an affordable all in one travel bag for quick 2-3 day business trips. I must say after my first trip this bag it performed flawlessly. It easily held 3 days worth of business attire plus my modest computer equipment. 3 shirts 2 pair of pants plus 1 pair of jeans fit without a hitch. What was very surprising was the amount of storage compartments built into the bag. It made organization very easy and the light gray lining makes things easy to find. I have traveled with an inexpensive Good Hope 3 way convertible as well as a Patagonia MLC. This bag sits squarely between the two and looks more professional than them.When the expansion zipper is closed it fits neatly under the airline seat! This was a key factor in deciding to go with this bag. It also fits easily into the overhead bins of regional jets.The only improvement is the shoulder strap. It is pretty standard. I upgraded the strap to one by optech that I use with all of my bags.I am looking forward to seeing how long this bag will hold up to weekly business travel. ### ⭐⭐⭐ Great design - not durable long term *by J***. on March 14, 2020* I've used this bag religiously since July 2019 and have thoroughly enjoyed its functionality (carrying capacity and modes of carry). Eight (8) months into using this bag one of the main compartment zippers will not remain closed. The 'teeth" of the zipper will not hold, which in turn now renders the bag unusable . Really unfortunately, I really liked the bag for these eight(8) months. It's not practical to buy a new bag every 8 months --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/94987344-convertible-briefcase-backpack-for-men-waterproof-zipper-multifunction-messenger-bag](https://www.desertcart.pl/products/94987344-convertible-briefcase-backpack-for-men-waterproof-zipper-multifunction-messenger-bag) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-24*
