Is Z Supply All Day Knit Jacket Worth It?

A jacket made entirely of knit fabric sounds like it should not work. Seven weeks later, this one has barely left my shoulders.

The Z Supply All Day Knit Jacket is the kind of piece that does not photograph particularly well but feels incredible in person. I grabbed it on a whim while ordering other Z Supply pieces for my Best Affordable Fashion Brands (2026) reviews, and it has become the most-worn layer in my closet. For context on how Z Supply handles other categories, my Is Z Supply Worth It? Honest Review After Four Months and Eight Pieces covers the brand broadly. But this jacket carved out its own niche in my wardrobe fast enough to deserve its own review.

What the All Day Knit Jacket Actually Is

Think of it as a structured cardigan with jacket details. It has a collar, button front, side pockets, and a hem that hits at the hip. But the fabric is a mid-weight knit, not woven. It has the silhouette of a chore jacket or a shacket, built from cozy knit material. The result is a layer that looks more intentional than a cardigan but feels more comfortable than a traditional jacket.

The knit has a slight texture to it, a subtle waffle-like pattern that adds visual interest without being busy. My color is a heather gray that goes with everything I own, which is partly why it gets worn so often.

Fit and Sizing

I ordered a small and the fit is relaxed without being oversized. The shoulders sit right at my shoulder line, and the sleeves hit at my wrist bone. At 5 feet 6 inches, the hem falls about three inches below my natural waist, landing at mid-hip. There is enough room to layer a tee or thin sweater underneath without the jacket feeling tight.

The jacket does not have a cinched waist or any shaping. It hangs straight from the shoulder, which gives it that boxy, easy look. If you prefer a more fitted jacket silhouette, this will not deliver that. The appeal is in the relaxed structure.

Warmth and Functionality

This is a transitional layer, not a winter jacket. It handles temperatures between about 55 and 70 degrees Fahrenheit well. Below that, you need something with more insulation. Above that, it is too warm for anything beyond air-conditioned interiors.

Within that range, it performs beautifully. The knit traps just enough warmth for cool mornings, breezy evenings, and over-airconditioned offices. I wore it as my only layer over a tee during early spring mornings and felt comfortable through mid-morning when I typically took it off. The pockets are deep enough for hands and a phone, and they do not stretch out or sag when loaded. https://www.amazon.com/s?k=z+supply+clothing&tag=tumbleweed03b-20

Fabric Quality and Care

After seven weeks and about eight washes, the fabric has held up remarkably well. No pilling, which was my biggest concern with a knit jacket. The texture maintained its pattern. The color did not fade. The buttons stayed secure. I washed on cold, gentle cycle, and laid flat to dry per the care instructions.

The fabric has a slight stretch that has not loosened over time. The jacket snaps back to its original shape after wearing. I have hung it, folded it, and stuffed it into bags, and it recovers without looking wrinkled or stretched. For a knit piece, that resilience is impressive. Z Supply All Day Knit Jacket on Amazon

What It Does Not Do

It is not windproof. The knit weave lets air through, so on a windy day, you feel it. It is not water-resistant in any way. Even light rain soaks through quickly. And because it is knit, it does not have the clean lines of a tailored jacket. It reads casual to smart-casual at best. If you need a layer for business settings, this is too relaxed.

The button-front closure also gaps slightly between buttons when you move. It does not gape open, but the knit stretches just enough that you can see slivers of your underlayer between the buttons. Not a problem with a high-neck tee underneath, but noticeable with a V-neck.

How It Compares to Other Layers

Against a traditional denim jacket like Z Supply’s own Z Supply Denim Jacket, the knit jacket is drastically more comfortable but less structured. Against a standard cardigan, it has more shape and intention. It occupies a middle ground that I did not know I needed. The closest comparison might be a well-made hoodie in terms of comfort level, but the jacket collar and button front make it look significantly more polished than any hoodie I own.

The Verdict

The Z Supply All Day Knit Jacket is the most-reached-for layer I have owned in a long time. It fills the gap between a cardigan and a jacket with something that feels better than either. The warmth range is specific, so it is not a four-season piece. But for spring mornings, fall evenings, and the constant battle with office air conditioning, it is close to ideal. At roughly $80 to $95 retail, I got my money’s worth within the first three weeks of wear. Z Supply Knit Jacket on Poshmark
