This is a good work or travel bag.
Color: Black, Size: Large
This is a good size bag, light with lots of compartments on the inside and outside of the bag. Fit my laptop perfectly with room for much more inside.

Best diaper/traveling bag!!
Color: Desert, Size: Large
Absolutely LOVE this bag!! The fabric of the bag was better than I even expected. It’s super soft, comfortable, easy to wipe down, has plenty of storage, sturdy even without stuffing it full, and is the perfect bag! It feels nice and thick without it being heavy. The zipper is also very durable and isn’t cheap feeling compared to other brands. I will definitely be ordering more in the future even to use for just traveling. I switched from a book bag diaper bag style to this bag and I feel like it holds even more! Plus, I love that you can expand this bag!! You won’t regret buying this one!!

My new travel bag!
Color: Chocolate, Size: Large
I love this bag. It will be my new travel bag, replacing my back pack. It has lots of pockets and looks fashionable. I love that it’s expandable. It will be helpful for those trips where I seems to bring back more than I originally packed. 🤭. The shoulder straps are long enough to give you adequate space to carry on your shoulder. I also live that it has a strap to put on that handle of your luggage. The size is perfect for fitting under the seat in front of you when flying. If it holds up during my next trip I will definitely return to purchase other colors. Great bag for the price!

10/10 favorite bag of all time.
Color: Chocolate, Size: Large
LOVE this bag so much!! I use it for work and it fits my change of clothes, lunch box, water bottle, headphones, book, and a little extra.
It fits everything you need with so many organizing pockets and tons of room, zipper is great, accessibility is great etc etc. It's nylon-ish feeling in terms of material, and washable which I love. Would recommend this as a dupe to baggu as well. I also love the chocolate color, my favorite!
