How to Tell if a Hoodie Is Well Made Before You Buy

Five checks to tell if a hoodie is well made before you buy: the fibre label, weight claims, seams, shape and ribbing, and what a shop can't show you.

You can't run a lab test in a shop aisle. You can still learn a lot about a hoodie in five minutes with the garment in your hands, if you know where to look and which claims to ignore. In October you're often buying the one heavy layer you'll wear until April, so it's worth getting right.

What follows is the order we'd check things in, with a note on which parts are backed by a published standard and which are just good habits.

Start with the label, because it's the only part the law covers

In Canada, the fibre content label isn't marketing. It's required under the Textile Labelling Act, and the Textile Labelling and Advertising Regulations set out what it has to say. Section 11 requires the fibre content and the dealer's name and postal address. Section 12 lets a dealer use a CA identification number in place of the name and address.

The Competition Bureau's summary of the rules puts the fibre part plainly: when a fibre makes up 5% or more of the total fibre mass, the label has to show its generic name and its percentage. The fibre names and fibre content have to appear in both English and French.

So read it. A hoodie sold as "heavyweight cotton" that turns out to be 60% cotton and 40% polyester isn't necessarily a bad hoodie, but it's a different hoodie from the one the hang tag implied. If the label is missing, cut off, or only in one language with no obvious reason, that tells you something about how carefully the whole thing was put together.

What the label won't tell you is weight, yarn, knit or how it was sewn. None of that is required. Everything below is on you.

Treat the GSM number as a claim, not a measurement

Fabric weight is usually quoted in grams per square metre. There is a proper way to measure it: ASTM D3776/D3776M, Standard Test Methods for Mass Per Unit Area (Weight) of Fabric, which sets out four options, from weighing a full roll down to cutting a small swatch. It measures the fabric. It says nothing about how the garment wears.

Two practical points follow from that. First, a GSM figure on a product page doesn't tell you whether it was measured, or measured before or after washing. Brands rarely say. Second, a heavier number isn't automatically a better garment. A loosely knitted fabric can be heavy and still feel thin and floppy. We've written more on that in how to break in a stiff heavyweight hoodie, where the stiffness of dense cloth is the point.

In the shop, do this instead:

  • Pick it up by the shoulders and let it hang. Dense, well-knitted cloth drops straight and holds its shape. Thin cloth collapses and the hood folds flat.
  • Hold a single layer up to a light. You'll see the knit structure through most fabrics. What you're looking for is evenness, with no thin patches or lines.
  • Pinch the body fabric and pull gently across the width, then let go. It should come back without leaving a stretched bulge.

Turn it inside out and look at the seams

This is the check most people skip and the one that tells you the most. Seams are a common place for a hoodie to fail, and the usual spots are the shoulders, underarms and pocket corners.

The reference here is ASTM D6193, Standard Practice for Stitches and Seams. It isn't a quality grade. It's a classification: it identifies the category, formation and general purpose of stitch types and seam types used in sewn items, with drawings for each, and an annex of seam assembly recommendations. Its value to a buyer is that it gives factories and brands a shared vocabulary. If a brand can tell you which stitch and seam type it uses at the shoulder, someone there has thought about it.

You don't need the vocabulary to see the difference, though. Inside the garment, check:

  1. Stitch evenness. Run a finger along the side seam. The stitches should be the same length all the way and sit in a straight line. Wandering lines and uneven spacing mean a rushed operator or a badly set machine.
  2. Loose ends. A few trimmed tails are normal. Long loose threads, or stitching that has already started to run back at the end of a seam, are not.
  3. Puckering. If the fabric gathers along the seam like a ruffle, the thread tension was wrong or the two layers were fed at different rates. It won't press out.
  4. Stress points. Look at the pocket corners, the bottom of the hood opening and the drawcord eyelets. Extra stitching or reinforcement there is a good sign. Bare, unreinforced corners on a kangaroo pocket are an easy place for a tear to start.
  5. Seam finish. Some hoodies cover the shoulder and side seams with a flat stitch, others leave an overlocked edge. Both can be sound. The trade-offs are covered in flatlock or overlock seams on a heavy hoodie.

Lay it flat and check the shape

Put it on a table, front up, smoothed out. The side seams should run straight down the sides. If one swings round towards the front, the panels may have been cut off grain, and that tends to get worse with washing, not better. Fold it in half down the centre front: the shoulders, cuffs and hem should line up.

Check the hood while it's flat. A hood that sits evenly, with both sides the same depth, was cut and joined with some care. A lopsided one won't sit right on your head no matter what you do.

Stretch the ribbing

Cuffs and the hem band take more stretching than any other part of the hoodie. Pull a cuff open to roughly the width of your hand, hold it for a second, and let go. Good ribbing snaps back to its original width. Ribbing that recovers slowly, or stays slightly wider, will be loose within a season.

This is a hand check, not a standard. We didn't find a published test method we could open and verify that maps neatly onto a two-second shop test, so treat it as a rough guide and nothing more.

What you can't judge in the shop

Pilling is the big one. The fuzzy balls that form on cotton after weeks of wear depend on fibre length, yarn twist and finishing, and you can't see any of that on a new garment. Labs measure pilling tendency with methods such as ASTM D3512/D3512M, which tumbles fabric samples in a cork-lined chamber and compares the surface afterwards. It's a useful test for a fabric mill. It's not something a brand typically publishes, and if one does quote a result, ask which method and which grade.

The same goes for shrinkage and colour loss. Both need repeated washing to measure. In the shop, the best you can do is read the care label and decide whether you'll follow it. Our piece on why heavy cotton pills covers what you can do after you've bought.

A few things that sound like quality and aren't

  • Price. It reflects brand, volume and margin as much as cloth and sewing. Expensive hoodies with bad seams exist, and the seam check above works the same at any price.
  • Softness on the rack. Very soft new fabric is often the result of finishing, and finishes can wash out. A slightly firm hand on a new heavy hoodie isn't a fault.
  • Heavy trims. Thick metal aglets and big branded tabs feel substantial. They tell you nothing about the seams behind them.
  • A big GSM number on its own. Without a method, it's a figure someone typed.

The five-minute version

Read the fibre label. Let it hang from the shoulders. Turn it inside out and look at the side seams and pocket corners. Lay it flat and fold it in half. Stretch a cuff and watch it come back. If it passes all five, it's probably well made. If it fails the seam check, put it back, whatever the price tag says.
