"I have had this bag for a little over a week and I am in love! It is so beautiful, has many area for organization and it held up beautifully when I was caught in a downpour. The rain beaded up and everything inside stayed dry. I’m so impressed. I wish I had bought one sooner. This bag is a winner and the beige color is so rich looking."
"I purchased this backpack 3 years ago for work and loved it so much. I got compliments all the time and the beige stayed surprisingly clean (other than the bottom)! Perfect interior and exterior pocket placement and really liked the flat pockets to hold random papers. Unfortunately, the zipper on the laptop sleeve broke recently and I think the cost to have it repaired will be nearly as expensive as getting a decent replacement from a less expensive retailer - so will be retiring my beloved Beis. Had the zipper lasted I would have been using this bag for work and plane travel for many more years."
"⭐⭐⭐⭐⭐ Exceptional Customer Service & Great Quality I had an excellent experience with BÉIS. Their customer service (Homer) was exceptional—quick, responsive, professional, and genuinely focused on resolving my issue. The entire process was handled smoothly, and communication was excellent from beginning to end. On top of the great service, I’m very happy with the quality and design of their products. It’s refreshing to see a company that not only makes great products but also stands behind them when it matters. Great experience all around. Highly recommend BÉIS!"
"Got this bag for work and travel and have to say I’m impressed. High quality zippers and material. Efficient and nice design. Holds my laptop, lunch, and everything I need. Can’t wait to travel. Oh and the color is lovely."
"Quality and design is what you can expect from Beis. It’s a great backpack with ample space and the material is durable and easy to clean. I liked the shape of the backpack and how even when it’s full it doesn’t seem too heavy on your back. I also liked the two handles on top that snap together so you carry like a bag. I did the free personalization on the trolley pass thru which was unique and I love it. Two requests/design flaws: the laptop sleeve section only has one zipper and really should have a double zipper, and there is no zipper on the trolley pass thru to make it into an extra pocket, as mentioned. I still love this backpack and will be using a lot for work and travel."
"I purchased this bag in 2023 and have used it for every flight I’ve taken since then! I’m an American living in Europe so I travel all the time, and if I have to take one bag with me, this is it. The expandable zipper is a lifesaver as someone who shops a lot on my trips. The bag is so durable and sturdy I would have expected it to break or get a hole by now but there is no sign of that happening anytime soon! Truly the best backpack I’ve ever owned and I will buy another one when my current one no longer works for me. Everyone should buy it!"
"This is the backpack I was looking for since I don’t know when. I’m particular when it comes to straps and look, and this one is perfect. Plenty of support without being bulky, practical and stylish. It stands up on its own. The optional bottle holder is perfect. I love the pockets without losing things in them. Very user-friendly. I just hope it lasts a long time! I’ve had it for a year so far."
"I’m loving the functionality, all the extras especially the hidden bottle holder, and how clever is expansion zipper ! Most of all my favorite is the style and color. Can’t wait to use it for my summer travels."
"It’s very functional, has great pockets, is comfortable to wear, and is really cute. I first got the maple, and unfortunately needed to replace it, and the second time I chose the beige one. I really prefer the maple - it has a very different texture/feel. It feels much more like cloth, while the beige one feels very plastic. It has a totally different texture/feel. The description says they’re made of the same material, but I’m very skeptical - the beige feels like a totally different bag. That’s really my only complaint."
"Very good quality and perfect but it doesn't fit my 16inch laptop wish it was a little bigger . I have to shove my laptop in it."
