"Thought I’d love this because of how many pockets it has, but I find the straps and how the bag sits on my back quite uncomfortable. My hubby feels the same. I also wish it had an exterior spot to hold a water bottle. Overall, I wouldn’t recommend purchasing this bag."

Reviews
Buy this!!
"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."
Love this bag!
"I use this bag for commuting for work in the city. My bag was stolen unfortunately and I tried to use another bag that I had at home and I was miserable. Repurchasing this bag was an absolute must. It holds everything that I need, comfortable and changeable to my needs for the day."
Expandable backpack great for carry on luggage
"Great addition to my set and the expandable space worked well for a carry on option for my cruise."
Loved for 3 years
"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."
"Love the size for every day use, color is perfect for Fall… makes my dressy outfits look a bit rebel without being messy I look balanced."
It Fits Everything!
"This backpack does it all. The design behind the size, its ability to expand, and the pocket varieties make it perfect for any occasion. Working in construction, this backpack is durable and it fits my laptop, tools, and any other items I may need to bring with me. The pockets allow me to stay organized in making sure everything that goes in the bag has a home. I got this in the color maple and it feels like a great color that can be used year round. Thank you for making a perfect backpack that does it all, from work to leisure I know I will always grab my Beis backpack."
My favorite backpack of all time
"This backpack is perfect!! the compartments, the expansion option and the aesthetics are top notch! I would buy every color if they all had the coating over the material like the beige and cream. The only thing to make it more perfect is to add a larger size of the same bag like a 28L that expands!!!!!!"
Exceptional Customer Service & Great Quality
"⭐⭐⭐⭐⭐ 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!"
"I love the design of this bag. well-organized for peace of mind and professional use."
Q&A
- Would the laptop compartment fit a Dell computer (9.75in W x 14.25in L x 1.25in D)? Centimeters are ~ 24.76W x 36.2L x 3.18D I think. I’ve tried a few bags before that I thought would fit based on their dimensions but they based their measurements on Macs so the depth was never right.
- Thank you for reaching out to Beis The Expandable backpack can fit a 13' and 15' Laptop Here is the link to the dimensions. https://beistravel.com/products/the-expandable-backpack-in-black?_pos=1&_sid=c3c18d24c&_ss=r Hope this information helps!
