Coterie The 360° Training Underwear Review

About Coterie The 360°

• Sizes: 2T–5T
• Weight accommodation: 20–38 pounds
• Style: Pull-on
• Materials: Plant-based chlorine-free wood pulp, polyacrylate, silicon dioxide, polypropylene, polyurethane
• Designed for: Potty training, overnights, naps, road trips, traveling

Coterie positions The 360° as a step up from typical training pants—something for parents who've moved past diapers but still want overnight reliability during potty training. The pull-on design and stretch waistband are meant to build a toddler's independence, letting them practice pulling pants down and back up solo, while the brand leans on the safety of its materials to set itself apart from mainstream competitors like Huggies and Pampers.

At roughly double the price of those brands, Coterie clearly positions The 360° as the premium option, betting that parents will pay more for cleaner ingredients and a more elevated feel.

Health & safety

Coterie bills itself as a dermatologist-tested and -approved diaper brand, proven safe for babies' delicate skin. But what does that mean exactly? In 2026, a third-party OEKO-TEX lab tested The 360° and certified its construction free of more than 1,000 potentially harmful compounds, which include but are not limited to 13 heavy metals, more than 120 pesticides, more than 20 chlorinated phenols (which can present as harmful environmental pollutants), more than 20 phthalates, and 24 volatile organic compounds (VOCs), including benzene and toluene.

Furthermore, in 2025, a dermatologist supervised clinical testing of The 360° on human subjects to confirm its hypoallergenic status. Researchers found it to be as gentle on the skin as water.

How we tested

My daughter currently wears regular cotton underwear throughout the day and Huggies Pull-Ups during naptime and overnight. After receiving a 23-count box from the brand, I noticed its soft, sustainable packaging, an ode to its contents. I then swapped her usual training underwear brand for the Coterie variation for a week, and she instantly took to it.

"No more Minnie Mouse?" she asked. I was nervous it would become a thing, but her inquiry stemmed from intrigue rather than disappointment.

After each nap or bout of overnight sleep, I assessed each pair for absorbency, fit, and odor control. They performed similarly to her existing brand, with a few caveats.

What we like

They're wonderfully soft

The first time I laid a hand on The 360°, I noticed how soft they were. As someone who's due to give birth in a couple of weeks, I thought about how I wish they made them in my size for postpartum care. The softness likely comes from apparel-grade cotton and other plant-based fibers, such as wood pulp, sourced from sustainably managed forests and designed to mimic the feel of cashmere.

While my 2-year-old might not have the awareness to appreciate the difference between these and her standard cotton pair, I sure do.

We've previously named Coterie the top luxury diaper brand worth upgrading for, and found its diapers to be absorbent and gentle on skin in previous testing.

They're absorbent

This training underwear lives up to its own claims of superior absorbency—which is all you can ask for. After a nearly three-hour nap (I'm lucky she's taken so well to her big-girl bed), there seemed to be about four wettings' worth of liquid in the training underwear, with zero signs of leakage. Whereas our usual brand feels like a step up from a swim diaper in the absorbency department (read: it's thin), Coterie's feels like it could retain a cup or two. Its patent-pending absorbent core is designed for older, advanced toddler potty trainers with larger bladders, and it shows in how heavy the diaper gets without leaking (most of the time).

The brand doesn't stipulate the exact volume of moisture it retains, but my daughter has stayed comfortable even after several hours of overnight sleep without being changed. What's more, even after making a large stool in her sleep, there didn't seem to be a looming threat of a blowout or overflow. The smell permeated her nursery, sure, but it was on par with how distinct the same smell is in her Huggies Pull-Ups.

They're made with great ingredients (and without bad ones)

We accidentally bought scented diapers on a trip. The irritation they caused to both her delicate skin and our nostrils made me vow never to repeat that mistake. So I appreciate the confidence these hypoallergenic, scent-free, lotion-free, everything-bad-free training pants instill.

I'm not typically the type to gravitate toward organic products, but I appreciate the opportunity to explore the role they play in our lives. These dermatologist-tested training pants are free of fragrance, latex, phthalates, heavy metals, and pesticides, and they're made with plant-based chlorine-free wood pulp. While testing Coterie's training underwear, I haven't felt the need to apply any zinc oxide diaper cream as a barrier to prevent diaper rash, since the material is gentle and forgiving on her skin.

They have a generous stretch to them

I compare their side paneling to the smocked details in a cinched garment—close-fitting enough to feel secure and supportive, yet stretchy and forgiving enough for easy on-and-off. That level of stretch facilitates independence when she pulls them down to use the toilet after naps and overnight sleep. They also don't overly squeeze her skin or cut off circulation like other stretchy pull-on styles I've tried.

What we don't like

They don't come with any orientation labeling

I was in a true state of panic when I first put my daughter in these, because I didn't know which way to face them. Unlike her usual brand, there was no "back" or "front" labeling to assist with orientation. There was a single Coterie label that I belatedly learned goes in the front. This design isn't intuitive for first-timers of the brand, and I would hate to have positioned the back at her front, and vice versa, only to miss out on any potential absorbency and fit benefits.

Their sizing runs large

Whereas she comfortably wears size 4T–5T made for kids weighing 38 to 50 pounds in her Huggies, the same size fits loosely in Coterie. She is currently around 32 pounds, but I opt for a size up to accommodate extra moisture or larger stools (at the recommendation of her daycare educator), and they fit seamlessly in her usual brand.

Here, I notice a bagginess to the fit that is likely distracting for her. During one nap while wearing a dress, I caught her on the baby monitor tugging at the loose fabric between her legs, which she had never done before and seemed to delay her nap by about 30 minutes. After one overnight sleep, her pajamas were drenched in urine, a leak I attributed to the sizing issue.

There's no adjustable side panel

Even if I wanted to send her to daycare in these, it would be against school policy. Unlike The Pant by Coterie, they don't feature refastenable side-panel tabs like a diaper, so you have to rip them off at the seams to fully remove them. There's no option to reattach them once ripped off.

Even more inconvenient, you'd need to completely disrobe your child of pants and shoes to put on a fresh pair, instead of being able to pop one on standing up, as I do while on the go without access to a changing table. Unlike the 360-degree pull-on pair from Huggies I bought before her daycare scolded me, these training pants require real elbow grease to rip off, which can make changes feel more labor-intensive and stressful when she's impatient.

The branding is bare-bones

Let them be kids! My daughter's face lights up any time she gets to spend a diaper change with Minnie Mouse. This training underwear seems to have adopted a beige mom quality with its minimalist aesthetic (hence the single Coterie label in the front), robbing kids of the bright colors and engaging characters that make ordinary tasks like a diaper change that much more exciting.

They're expensive

On Amazon, 92 pairs of Coterie training underwear cost $120, which comes out to $1.30 per pair. On its direct-to-consumer website, a pack of 92 pairs costs $105.50, which comes out to $1.15 per pair. The Huggies I usually buy cost $40 for an 82-pack, which comes out to 49 cents per pair. I won't have to take out a mortgage on my home to afford Coterie diapering essentials any time soon, but it will make a dent in my spending. However, the extra spend might be worth it if you prioritize its strong suits.

Warranty

Coterie The 360° training underwear doesn't come with a warranty, and packs are nonrefundable and nonreturnable once opened. If you'd like to get rid of an unopened pack, Coterie will send you a shipping label to donate it to a local charity through its Diaper Give Back program.

Should you buy the Coterie The 360°?

Yes, if you've got disposable income and value organic baby products

If you've got room in the budget and you read ingredient lists, the Coterie The 360° (available at Coterie) earns the upgrade. It delivers on the two things that matter most during naps and overnights: a plush, apparel-grade feel my daughter took to instantly, and an absorbent core that held roughly four wettings' worth of liquid through a three-hour nap without a drop of leakage—even after a middle-of-the-night stool. The stretch side panels let her pull them down and back up on her own, which is the whole point of potty training, and the fragrance-free, latex-free, phthalate-free build meant I left the zinc oxide cream in the drawer all week. At $1.15 to $1.30 per pair, you're paying roughly double what a mainstream pull-up costs, but if a dry crib and a clean ingredient list are what keep you up at night, that's a fair trade.

No, if you'd rather put the money toward other baby gear

If, like me, you'd rather devote your funds toward baby gear that might have a more immediate impact on their quality of life, from toys to family trips and after-school activities, skip them. Due to the lack of refastenable side panels, I couldn't send her to daycare in them even if I wanted to, but I do appreciate their pillowy, plush silhouette, cleaner ingredients, and impressive absorbency, which make for a comfortable nap or night of sleep any time I've got access to a changing table.
