Z Supply Pajamas Review: Four Months, Three Sets, Honest Verdict

I’m a pajama snob. I’ve tried Eberjey, Lake, and Parachute. Z Supply’s lounge line doesn’t beat them — but at roughly a third of the price, it doesn’t need to.

I’ve owned three Z Supply lounge sets for about four months now, rotated through more laundry cycles than I can count, and I have a clear sense of where this line wins and where it falls short. This review is part of the broader Affordable Fashion Brands coverage and sits alongside the main Is Z Supply Worth It?. If you want the executive summary on whether Z Supply is the brand for you, start there. If you specifically want the loungewear verdict, this is the article.

The Z Supply loungewear lineup

Z Supply’s loungewear has a few distinct categories and they are not interchangeable. The slub tank family is technically day-wear but lives halfway into the loungewear conversation because it’s what I sleep in during summer. The formal lounge sets are the tee-and-joggers combos in matching rayon-modal blends. The pajama sets proper are the longer-sleeve, longer-pant combos designed for sleeping specifically. And there’s a satin sub-category I am about to tell you to skip.

The slub tank is the single best piece in the entire Z Supply catalog in my opinion and I’ve written about it at length in the main review. As a summer sleep top it is genuinely excellent — the fabric breathes, it drapes without clinging, and it wakes up looking cleaner than any T-shirt I’ve slept in. I own three of these and I’d recommend starting with one if you’re new to the brand.

The rayon-modal lounge sets are the cult-favorite pieces. These are the tee-and-joggers combos that show up on Instagram stories and that I see in the comments under every Z Supply post I click on. They live up to the reputation. The fabric is softer than any equivalent loungewear I’ve worn at the same price point, the cut is relaxed without being sloppy, and the colors are muted enough that you can wear a lounge set to the coffee shop and not feel like you’re in pajamas.

The proper pajama sets — longer sleeves, longer pants, heavier construction — are where Z Supply is competing directly with the premium pajama brands. This is the category where the comparison gets interesting.

The satin line is where the brand has no business being. I mentioned this in the main review and I’m repeating it here because some of the satin pieces are marketed as loungewear and they shouldn’t be. Slippery, fragile, badly finished. Skip.

Fabric hand-feel and care

The rayon and modal blends that Z Supply uses across its loungewear are what make the whole line work. Rayon is cool against skin, drapes like silk, and takes dye in a way that makes the colors look expensive. Modal adds softness and a slight stretch recovery that rayon alone doesn’t provide. Together they create a hand-feel that I would genuinely mistake for something more expensive if I didn’t know better.

The trade-off, same as with every Z Supply piece, is that rayon and modal are more delicate than cotton. You cannot shove them in a hot dryer and expect them to come out looking the way they did. I wash mine on cold, inside-out, and I line-dry everything. After four months and many washes across three sets, I have one small fabric pull on one lounge set that happened when I caught a sleeve on a door handle. No pilling. No color fading beyond minor break-in. No stretched-out waistbands or rolled hems. The construction is holding up.

If you’re the kind of person who wants to throw everything in a hot wash and a hot dryer, Z Supply loungewear is going to disappoint you. The delicate-cycle lifestyle is not extreme for these pieces, it’s expected. Adjust your laundry habits or buy cotton.

Fit notes and sizing

Z Supply lounge tops run slightly small in my experience. The relaxed cut that’s supposed to be oversized ends up fitting closer to body-hugging on me if I take my usual size, which is the opposite of what the photography suggests. If you want the relaxed oversized look that the brand photographs — the slouchy sleep-shirt silhouette — size up one on the tops. On the bottoms, sizing runs closer to true, maybe a touch generous at the waist.

For the matched lounge sets specifically, I size up on the top and take my true size on the bottom. This is annoying because sets are not always sold that way and you may have to buy two sets in different sizes and return the pieces you don’t need. Worth the hassle for the fit you actually want. On the pajama sets proper, the sizing is more consistent across top and bottom — I take my true size on both and it works.

Z Supply vs. Eberjey, Lake, and Parachute

Here is the comparison you are probably running in your head if you’re reading this article. I own pieces from all three premium brands and I’ve worn them against the Z Supply sets back-to-back.

Eberjey wins on silhouette and the specific feel of their proprietary fabric. The Gisele pajama is still the best pajama I own in a strict construction-and-fabric sense, and nothing Z Supply makes beats it.

Lake is the fabric winner for me on cotton blends specifically. Their pima cotton pajamas are unmatched in that category.

Parachute sits somewhere in between, better than Z Supply on construction and inferior to Eberjey and Lake on the specific standout details.

Z Supply’s position in this comparison is not “just as good as the premium brands.” It’s “close enough to the premium brands that at one-third the price, most buyers should start here.” That is a real category position and it’s the reason the Z Supply loungewear cult is real. If you have been considering an Eberjey Gisele and you’ve paused at the price, try a Z Supply lounge set first. If you end up loving it, you’ve saved a meaningful amount of money. If you end up wanting more, you know exactly what you’re paying for when you upgrade.

The verdict — who Z Supply loungewear is for

Yes if you want elevated-basics loungewear at a price that doesn’t hurt and you’re willing to wash it on cold and line-dry. Yes if you’ve been pricing premium pajama brands and flinching at the numbers. Yes if the slub tank is already on your list from the main Z Supply coverage, because it doubles as a sleep top and a day piece. Yes if you value soft hand-feel over rugged construction.

No if you want indestructible loungewear that survives hot-wash hot-dry abuse. No if your house runs hot and you need a pajama that breathes like pure cotton. No if you’re shopping specifically for printed pajama sets — those have been the most uneven category in Z Supply loungewear and I’ve returned one myself.

FAQ

Does Z Supply run small?

Yes on lounge tops specifically. Size up one if you want the relaxed oversized look the brand photographs. The bottoms run closer to true to size and I take my usual number. Pajama sets proper are more consistent across top and bottom.

How do you wash Z Supply rayon?

Cold wash, inside-out, line dry. Do not put rayon and modal pieces in a hot dryer. A brief low-heat tumble is okay if you need to reset shape, but hanging dry is the safer default. I’ve had no issues with shrinkage or fabric damage following this routine across three sets and four months.

Are Z Supply pajamas worth it compared to Lake?

Different categories. Lake wins on pima cotton pajamas and on construction detail. Z Supply wins on price and on the specific rayon-modal hand-feel that Lake doesn’t make. If the category you want is cotton-forward traditional pajamas, Lake is the better choice. If the category you want is soft, draped, elevated lounge sets, Z Supply wins on value and arguably on texture.

Can Z Supply loungewear go in the dryer?

Brief low-heat tumble is survivable but not recommended. The rayon and modal blends are more durable than people assume but they are still more delicate than cotton, and the combination of heat and tumbling is the single fastest way to shorten the life of a piece. Line dry when you can, and if you absolutely must use the dryer, pull the pieces out while they are still slightly damp and finish drying on a rack.
