Z Supply Sweatshirt Review: Two Pieces Through a Full Winter

Z Supply sweatshirts trade softness for structure. That’s great for lounging. Less great if you want something that holds its shape past year one.

I own two Z Supply sweatshirts — a cropped relaxed crew and a longer pullover — and I’ve worn them through a full winter to have a real position on whether the brand’s sweatshirt line earns a place in your rotation. This review is part of the broader Affordable Fashion Brands coverage and sits alongside the main Is Z Supply Worth It?. If you’re deciding whether Z Supply is worth your attention at all, read the main review first. If you specifically want the sweatshirt verdict, this is the article.

The Z Supply sweatshirt lineup

Z Supply’s sweatshirt catalog has a few distinct categories. The cropped relaxed crew is the most Instagram-forward piece — boxy cut, shortened hem, meant to be worn with high-rise bottoms. The longer pullover is the more traditional sweatshirt silhouette. The fleece pieces are a heavier subcategory that overlaps with the brand’s outerwear lineup. And there are sometimes quarter-zip variants that function as athleisure crossover pieces.

I own the cropped crew and the longer pullover. The cropped crew is the piece I reach for more often, partly because of how it looks with high-rise denim and partly because the boxier fit has held up better over the winter than the longer pullover. More on that in a minute.

The category I do not own but would like to test is the quarter-zip variant — it’s the piece that bridges loungewear and athletic casual, and it’s the one Z Supply most directly competes with Alo and Lululemon on. Maybe a future review.

Fabric: the soft-but-slouchy trade-off

Here’s the honest fabric story. Z Supply sweatshirts are made from a brushed-interior cotton-blend fleece that feels genuinely soft out of the bag. The hand-feel is noticeably softer than a Madewell or Everlane sweatshirt at similar or higher prices. If you’re putting the piece on for the first time and the thing you care about is whether it feels nice against your skin, Z Supply wins this comparison almost unconditionally.

The trade-off is that softness and structure are in tension. The same brushed interior that makes the piece feel so good is also the thing that pills earlier than harder-fleece alternatives. The same relaxed cut that photographs well is also the thing that stretches out over time. My cropped crew has held its shape well — the shorter length means there’s less fabric to stretch. My longer pullover has visibly relaxed through the torso over the course of the winter in a way that makes it look slouchier than when I bought it.

Is the slouchiness good or bad? That depends on what you wanted from the piece. If you wanted a lived-in sweatshirt that would feel like an old friend by the end of the season, you’ll love it. If you wanted a crisp silhouette that held its shape for years, you’ll be disappointed. Z Supply is not Alo. Adjust expectations accordingly.

Fit notes and sizing

The cropped crew runs relaxed and I took my usual size. The photography suggests an oversized fit but mine fits close to body-hugging at the smaller size and closer to true relaxed at my size. If you want the oversized look that the brand photographs, size up one. If you want a closer fit, take your true size.

The longer pullover runs slightly larger than the cropped crew at the same size number. I took my true size and the pullover is slightly loose through the shoulders in a way that became more pronounced after several washes. Next time I’d size down one on the longer pullover specifically.

For both pieces the sleeve length runs slightly long, which I consider a feature rather than a bug on a relaxed sweatshirt. If you hate that look, consider the fit math above and size accordingly.

Body-length sizing on sweatshirts is always more forgiving than on dresses or fitted pieces. These are lounge pieces. You have more margin for error than you’d have on a tailored garment.

Wash and wear after four months

I wash my Z Supply sweatshirts on cold, inside-out, and air-dry. After roughly ten washes per piece across four months, here’s the condition.

The cropped crew has held up well. Minor pilling under the arms and along the inside of the sleeve where it rubs against the torso. Color has held. No visible stretching. No seam issues.

The longer pullover has held up less well. The same minor pilling under the arms, but more visible stretching through the torso and at the hem, and the neckline has softened slightly where it meets the shoulder. It still looks good enough to wear and I’d still recommend it, but I can see it reaching the end of its useful life by the end of next winter — maybe twelve to fifteen months total from purchase to retirement.

Neither piece has gone through the dryer. If you put these in a hot dryer, the lifespan drops faster than I’d want to guess — the brushed interior is particularly sensitive to heat, and the stretchy cotton blend loses structure when repeatedly heat-dried. Stick to cold wash and air dry if you want the pieces to last.

My honest negative: the longer pullover is the piece I regret buying. Not because it’s bad, but because it’s the category where Z Supply’s structural compromises show up most clearly, and I’d have been better off spending slightly more on a firmer sweatshirt from another brand. The cropped crew I’d buy again. The longer pullover I’d replace with something more structured next time. For the cardigan alternative that I find more versatile for layering, the Z Supply Cardigan covers my recommendations in that category.

If you’re comparing the sweatshirt category against the rest of the Z Supply catalog, the right framing is that the sweatshirts are the category where the brand’s philosophy — soft hand-feel, relaxed silhouettes, gentle-wash requirements — runs into the hardest test. Soft sweatshirts are easy to make feel good on day one. Making them hold their shape for two years is harder, and Z Supply is not the brand that has solved that particular engineering problem at this price point. The loungewear line holds up better. The dresses hold up better. The sweatshirts are the weakest durability category in the catalog in my experience.

That said, one reason I still bother owning these pieces is that the brand’s overall aesthetic cohesion is strong enough that a Z Supply sweatshirt layers perfectly with a Z Supply lounge bottom in a way that reads as intentional. If you’re building a Z Supply-forward closet, the sweatshirt is the piece that ties the loungewear section together visually, and that kind of cohesion is worth the durability compromise for some buyers. For the full Z Supply loungewear coverage, the Z Supply Pajamas breaks down the sets that pair well with the sweatshirt line.

The verdict — buy this one, skip that one

Buy the cropped relaxed crew. It’s the Z Supply sweatshirt that most clearly earns its place in the rotation. The boxier fit holds up better than the longer silhouettes, the styling range is widest with high-rise bottoms, and the hand-feel is consistent with the rest of the brand’s elevated-basics promise.

Skip the longer pullover if you want structure. Consider it only if you specifically want a lived-in, slouchy piece and you’re fine with it looking more relaxed by the end of its first season. If you want a crisp sweatshirt silhouette that holds its shape for multiple years, buy from a brand that competes more directly with Alo or Lululemon — Z Supply is not trying to be that brand and will disappoint you in that comparison.

For current listings, https://www.amazon.com/s?k=z+supply+clothing&tag=tumbleweed03b-20 is the deep link to the brand’s sweatshirt collection. Z Supply Sweatshirt on Amazon covers the Amazon marketplace listings with the usual verify-the-seller caveats. I’d recommend buying direct or through Revolve for new pieces rather than Amazon, because the fabric story on these sweatshirts is exactly the kind of thing Amazon counterfeiters get wrong.

FAQ

Do Z Supply sweatshirts shrink?

Minimally if you wash cold and air-dry. If you put them in a hot wash or a hot dryer, expect some shrinkage and more pilling over a shorter period. The cotton-blend fleece is sensitive to heat and the care instructions should be followed closely if you want the piece to last.

How are Z Supply sweatshirts sized?

Cropped crew runs relaxed and true to size. Longer pullover runs slightly larger and may benefit from sizing down one if you want a closer fit. The photography leans into oversized proportions; actual fit is closer to relaxed rather than truly oversized.

Are Z Supply sweatshirts warm?

Moderately. The brushed interior fleece provides real warmth in the same range as a standard mid-weight sweatshirt. They’re not parka-level warm, but they’re warmer than a plain cotton T-shirt or a long-sleeve waffle top. I wear mine as a mid-layer under a jacket in deep winter and as an outer layer on milder days.

Can you machine wash Z Supply sweatshirts?

Yes, on cold, inside-out. Do not put them in a hot dryer — air dry or tumble on low if you must. Cold wash and air dry is the routine that maximizes the useful life of the piece.
