The Modern Slub tee is Z Supply’s most copied piece. You can walk into any boutique in the country and find a knock-off slub tee sitting on a fold table, usually at a lower price and usually with the fabric weight done wrong. I’ve tried a handful of them. The original still holds up.
I’ve owned my Modern Slub for about a year, in two colors, worn hard through maybe forty days of rotation each. This is a zoomed-in review inside my broader Affordable Fashion Brands coverage. If you want the full Z Supply tee category, the Is Z Supply T Shirts Worth It? covers it, and the main Is Z Supply Worth It? has the brand-level take.
Why slub fabric matters
Slub is a yarn with intentional thickness variation — thin in some sections, thick in others. When it’s knitted into fabric, the result has a subtle horizontal texture that catches light differently than smooth jersey. From a distance you don’t notice. Up close, it reads as deliberate and slightly elevated, not like a plain cotton tee.
Most mass-market slub fabric is cheap. It’s either too loosely knit (so the tee feels see-through and flimsy) or the slub is too aggressive (so the texture looks lumpy rather than intentional). The Modern Slub is neither. The slub is fine enough to add dimension without looking like a texture-forward novelty, and the knit is dense enough to be opaque but still drape.
This matters because the entire argument for a slub tee over a regular tee is the visual effect. If the fabric isn’t doing the work, you’re paying a premium for nothing.
Modern Slub construction specifics
The fabric is a rayon-poly-blend jersey with a slub yarn. It’s not pure cotton, which I’d call a feature rather than a bug — the rayon adds drape and the poly adds recovery. The tee doesn’t look cheap the way an all-poly tee can. It just looks soft.
Construction is better than Z Supply’s average. Shoulder seams are reinforced. The neckline is a proper ribbed crew, not a folded-and-topstitched cheap crew. Side seams are clean. Hem is double-stitched and hasn’t curled on either of my tees. After a year of washing this is the one Z Supply piece I own that hasn’t shown a construction weak point anywhere.
Silhouette is “modern fit” — which Z Supply means as close to body without being fitted. It skims the torso with a slight easeline rather than clinging. The sleeves are cap-to-mid-bicep length depending on your arm, and the neckline is a wider crew that shows a bit of collarbone.
Color and wash notes
I own mine in black and in oatmeal. After a year:
The black has faded to a “softened black” rather than the true black of day one. This is normal for any black tee and I’m not counting it against the Modern Slub specifically. If you want the tee to stay aggressively black, you need to wash inside-out in cold water and never tumble dry. I do both and mine still softened slightly.
The oatmeal is basically identical to day one. No yellowing, no color shift. It’s picked up one small stain I couldn’t get out, which is my fault and not the tee’s. The color has held up better than any other oatmeal tee I own, including the Madewell equivalent.
For the shrinkage question: I air-dry both and neither has shrunk meaningfully. If you tumble dry on high, expect some shrinkage through the body. That’s true of any rayon-blend tee.
Modern Slub tee vs. Relaxed Slub Tank
This question comes up every time I mention the Modern Slub. The Relaxed Slub Tank is the sleeveless cousin of the Modern Slub tee, and people wonder if they should buy both or pick one.
They’re genuinely different cuts. The tank is intentionally looser through the torso — more drape, more “intentionally oversized” than the tee’s close-but-not-fitted read. The tank is for tucking into high-rise jeans or wearing knotted. The tee is a standalone close-to-body layer.
I own both and wear them in different moods. If you can only buy one, get the Modern Slub tee first. It’s the more versatile piece and the more technical garment — the slub is doing more work in a tee silhouette than in a tank, because you’re seeing more of the fabric surface.
Honest negative: the Modern Slub tee is the Z Supply piece I most often catch myself wearing when I should be wearing something else. I mean that literally — I reach for it because it’s the most comfortable structured tee I own, and then I wear it to things where a cheaper tee would have been fine. That’s a luxury problem but it’s also a real one, because cost-per-wear is great and wear-per-piece is uneven across my wardrobe.

The verdict
Buy the Modern Slub tee. This is the single most justifiable Z Supply piece for anyone testing the brand, and the one recommendation I’d make with no caveats. Start with black or oatmeal, in your regular Z Supply size, and give it six weeks in rotation. If the fabric hand-feel works for you, buy a second color. If it doesn’t, you’ll know within a week.
The knock-offs I’ve tried — from boutique house brands, from fast-fashion adjacent labels, from the same category competitors — have all missed the specific slub density and fabric weight that make this tee worth what it costs. I’m not normally sentimental about basics, but a year in, this is the tee I reach for when I want to look put together without trying. That’s the whole pitch of elevated basics, and the Modern Slub is the rare Z Supply piece that makes me say yes, the premium is real.

FAQ
Is slub fabric durable?
Z Supply’s slub specifically, yes. The rayon-poly blend has recovery and the knit is dense enough to resist snagging. After a year of regular wear my tees show no fabric breakdown — just some normal color softening on the black.
Does the Modern Slub tee shrink?
Not meaningfully if you air-dry. Tumble-drying on high will shrink the body slightly, as with any rayon blend. I hang-dry both of mine and neither has lost length after a year.
What’s the best Modern Slub color?
Black is the most versatile and the most likely to stay in rotation year-round. Oatmeal is the best at holding its color and reads as softer. Buy one of those first before branching into the seasonal colors.
