## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality construction and smart design
*by M***6 on September 18, 2023*

I’m really happy with this bag. It's sold as a baby bag but it actually works really well as an easy to clean travel bag for an adult. It has a great combination of interior and exterior pockets to organize clothes, electronics and toiletries and has both security pockets and quick access convenience pockets so it’s great for short trips or day outings.The main compartment has open mouth stretch pockets, sleeve pockets and a couple of zippered “wet pockets” to store items that could leak. It includes interior bottle holders and has an expansion zipper on the outside of the bag that grows the main compartment a full 2 inches deeper.The smaller (not small) front compartment works great as a snack stash zone for road trips - 3 thermal pockets designed for baby bottles can hold chilled soda cans or bottled sport drinks and it has a zippered mesh pocket to keep snack bars and such organized.To secure your valuables, when worn as a backpack, there is a hidden zippered pocket against your back and can’t be accessed until you take off the pack. The front side has a second discrete zippered pocket that is very deep and can be used to hold a tablet or other valuables so you can get into it from the outside but it can’t easily be “picked“ in a crowd. Both of these pockets discreetly tuck the zipper tag out of view but all of the zippers have easy to grab tabs (even by my older, less nimble fingers).The front has a no zip quick access pocket I use for a pen, paper, maps, etc. Another quick access feature I like is the side pocket that has a slit opening so you can get fast access to baby/hand wipes or a travel sized box of tissues without digging around inside the big compartments. The other external side pocket is elasticized so it can hold various sizes of water bottles.It is well made from quality materials and with extra stitching at key stress points like the shoulder straps, tote handles and outside pockets. The interior is made of easy to clean materials and the outside is heavy duty cloth that will hold up over time. The zippers are smooth to open and close and have big enough grab tabs find them quickly.

### ⭐⭐⭐⭐⭐ The best diaper bag and we've tried plenty!
*by J***N on January 23, 2025*

We have tried several diaper bags and honestly, none of them compare to this one. This one has everything you need:- spacious- lots of pockets for organization- comfort- efficient designWe can fit in it:- diapers- wipes- diaper cream- portable phone charger (also comes with cord to plug your charger into)- changing pad (came with the bag)- wet bag (also came with the bag)- sound machine with carrying case- pouch for spare clothes- pouch for medicine- toy book for baby- formula container- burp cloths- bibsAll of this and then some and the bag still doesn't feel overly heavy and we still have plenty of room. I highly recommend. The bottom front pouch is also detachable and comes with a strap to transition to a crossbody! I took this pouch off because we didn't need it and it made it fit better in our backseat. I love this bag! It's a great price, sturdy material, functions well and is exactly what we needed.

### ⭐⭐⭐⭐⭐ Amazing Backpack! Exceeded expectations!
*by R***5 on November 18, 2022*

This diaper bag/backpack has it all: function, style, storage and quality! We bought this backpack to use for family outings and hikes. We're past the diaper stage but were in the market for a nice neutral looking backpack and this one caught our eye because of how it looks. We chose the gray color and it looks even better than expected! Very stylish!! We just got it but used it for a nice long hike today and could not be happier.It feels like whomever designed it put so much thought into the nice creature comforts that we didn't even expect. It has so much storage inside (and outside) that each of us had our own independent areas for storage! It has a nice removable bottle bag and we used that to keep our snacks cold with a small ice pack.Other things that we love about it are 1) the wipe/tissue pocket, 2) the anti-theft back side pocket to secure phones and keys, 3) the usb charging port (OMG so convenient!!) and 4) how the backpack stays upright while sitting on the table for loading and unloading! No flopping over. It sits up by itself.It has nice cushioning on the straps and the back too. That made it super comfortable to carry all day long. The zippers appear to be high quality and durable. We also love the brown leatherish zipper pulls.Like I said, it seems like someone put a TON of thought into this bag. Our expectations were pretty high and they have been far exceeded. Kudos to the manufacturer of this awesome backpack/diaper bag/travel bag.
