Shay Mitchell just made the diaper bag you didn’t know you needed

As a commerce editor who’s evaluated countless diaper bags over the years, I can tell you that finding “the one” is about as personal as choosing your wedding dress. But every once in a while, a product comes along that genuinely exceeds expectations—and the new BÉIS Ultimate Diaper Backpack has raised the bar for what a diaper bag can be.

Before diving into my hands-on experience, a bit of context: BÉIS (pronounced “base”) isn’t your typical baby gear brand. Founded in 2018 by “Pretty Little Liars” actress Shay Mitchell, the company started as a travel brand with a simple mission: create stylish, thoughtfully organized luggage that doesn’t require a trust fund to purchase. The story goes that Mitchell sketched her initial designs on airplane napkins during countless flights, focusing on solving real travel organization problems while keeping style and affordability in mind.

This approach to practical luxury is evident in their latest release—an upgraded version of their already popular diaper backpack. The new Ultimate version features several meaningful improvements: a larger changing pad (parents of toddlers, rejoice), a wider main compartment opening that actually lets you see what’s inside, and smartly redesigned pockets throughout. It comes in four versatile colors (black, olive, camel, and atlas pink) that look more “luxury travel bag” than “baby gear.”

Let me be clear: this isn’t just another diaper bag—it’s essentially a portable command center for parents. After putting it through its paces, I can confidently say that BÉIS has managed to create something that feels revolutionary in a category that honestly hasn’t seen much innovation lately.

BÉIS diaper bag organization and storage features

Let’s dive into what matters most with any diaper bag: organization. The main compartment features a wide-mouth u-shaped opening that gives you a full view of what’s inside, effectively solving the black hole problem that plagues most diaper bags. Inside, you’ll find a padded laptop compartment (because let’s be real, most of us are juggling work and parenting), thoughtfully designed mesh pockets, and elastic slip compartments that keep everything from spare outfits to snacks perfectly sorted.

The ultimate changing station: What sets the BÉIS diaper bag apart

But the real genius is in the details. The changing station setup is possibly the most well-executed I’ve ever seen. When you unzip the back panel, you’re greeted with a changing pad that’s legitimately twice the size of what you typically find in other bags—we’re talking big enough for those toddler diaper changes that feel like wrestling an alligator. The organizational pockets in this section are pure gold, with dedicated spaces for wipes and diapers that make one-handed changes actually possible. And while I’m not sure this is brand-sanctioned, since I no longer have diapers to change I plan to use it like one of those fold out camping pads at my kids’ soccer games. (Motherhood turns all of us into innovators, doesn’t it?)

Innovative features of the BÉIS Ultimate Diaper Backpack

One of my favorite features is the removable front pouch. It’s basically a stylish crossbody in disguise, and it’s brilliant for quick trips or tag-team parenting. The best part? It’s actually cute enough to use on its own when you’re having a kid-free moment. The magnetic closure is compatible with most wipe packages, making it perfect for those emergency diaper situations that always seem to happen at the most inconvenient times.

The exterior is equally impressive, with insulated bottle pockets that actually work (goodbye, lukewarm bottles), a phone pocket on the shoulder strap that fits even my giant Pro Max iPhone, and stroller straps included—because paying extra for those should be illegal at this point. They’ve even included a legit stink-proof wet bag and pacifier pouch, which typically cost extra with other brands.

BÉIS Ultimate Diaper Bag pros and cons

Now, no product is perfect, and I do have a couple of minor gripes. When fully loaded, this bag has some heft to it—though the newly designed, wider shoulder straps do an admirable job of distributing the weight. I also wish they’d added feet to the bottom to keep it off the ground, but the stain-resistant, odor-proof material does help mitigate this concern. While the changing pad is easily wipeable, I’d prefer it was removable for those times when you really need to give it a proper hose-down after a particularly memorable diaper situation.

That said, as someone who stands at 5’2″, I have to give major props to the proportions of this bag. Most backpack-style diaper bags are too long for my short torso, but this one’s shorter, wider design hits right at my waist—a game-changer for those of us in the petite camp who often struggle with backpack fit.

Is the BÉIS Diaper Bag worth It? Final verdict

The bottom line? If you’re in the market for a diaper bag that combines style, function, and durability, the BÉIS Ultimate Diaper Backpack deserves a serious look. It’s clear that every feature was designed with real parent problems in mind, from the key leash (because who hasn’t lost their keys in a diaper bag?) to the expanded changing pad. While at $198 it’s definitely an investment, the included accessories and thoughtful design make it worth every penny—especially considering you’d pay extra for these add-ons with other premium diaper bags.

After years of reviewing baby gear, I can honestly say this bag stands out in a crowded market. In a category that often asks parents to choose between function and style, BÉIS has managed to deliver both—while solving real problems that make daily life with little ones easier. And really, isn’t that what we’re all looking for?
