After a full year of constant use—airplanes, road trips, and traveling across multiple states—our Lily & Sol diaper bag has truly proven itself. We’re about to take it international, and I have zero doubts it’ll hold up just as well.
It’s easily the best diaper bag we’ve owned. It keeps everything organized, holds up beautifully with heavy use, and has made busy days (especially Disney trips) so much easier. Durable, functional, and actually designed for real life with kids—highly recommend.
After a full year of daily use, I can confidently say the Lily and Sol D Koa Diaper Backpack in Caribbean Onyx is hands down the best diaper bag we’ve ever owned.
My wife picked it up at the Orlando Family Convention in 2025 for our son Costa, and it has exceeded every expectation since day one. This isn’t just a diaper bag—it’s truly a “family adventure backpack,” exactly how it’s described. Whether we’re running errands, spending long days at Disney, or traveling on airplanes, this bag has been our constant go-to.
What really stands out is how incredibly well thought out the design is. Every compartment and pocket serves a purpose, and everything has its place. You’re never digging around trying to find wipes, bottles, or snacks—it’s all organized in a way that just makes sense. The extra-large capacity is a game changer, especially for longer outings.
The quality is also top-tier. The materials and construction feel premium and durable, and even after a year of heavy daily use, it still looks and performs like new. The sleek, luxury look is a nice bonus too—it doesn’t feel like you’re carrying a typical bulky diaper bag.
Some standout features we’ve come to rely on:
* The detachable wet bag is incredibly useful for soiled clothes or unexpected messes
* The oversized changing mat is perfect, especially now that Costa is older—it actually accommodates toddlers comfortably
* The convertible design makes it easy to switch up how you carry it depending on the situation
* The luggage sleeve that converts into an extra pocket makes traveling so much easier
And the fact that it’s machine washable is huge—because let’s be honest, with kids, that’s not optional.
We actually saw the owner again yesterday at the Prego Convention, and it was genuinely a pleasure. You can tell a lot of care and intention went into creating this bag, and it shows in every detail.
Honestly, there’s nothing I would change about it. If anything, I just think every parent with a baby or toddler should own one. It’s one of those products you don’t realize you needed until you have it—and then you can’t imagine going without it.
Amazing bag, use it every day. Also just took it with us to Disney and it made things SO much easier, especially having the cooler part for bottles and drinks. We stuffed so much in it and still had some space. Really great for a full day.
Hands down the most useful travel backpack we’ve ever had. Traveling with kids is so hard, you need so much stuff with you- this bag truly had pockets for everything and made it so much easier going on a flight with a toddler and a baby. Plenty of bottles, snacks, changes of clothes, diapers, wipes, ipad and toys. And the huge changing mat is just amazing. Went through security easily (pulled out bottles easily to get tested too), good size for carry on, fit on luggage perfectly, and even got it under the seat in front of us during the flight. I feel like we had 3 different small bags we were trying to use the last time we did this. Really truly the best family travel bag. If you’re on the fence, get it.
Finally found a diaper backpack that both my wife and I love. The Koa is super practical, fits all the baby gear plus stuff for our two older sons, and has a nice neutral look so I don’t mind wearing it. I’m also tall and broad and it fits me well. Nice big straps. The giant cooler pocket and wet bag are genius. Really has everything you could need. 10/10 recommend.
