Sweater vs Sweatshirt: What's the Difference?
A sweater is knitted from yarn; a sweatshirt is cut-and-sewn from looped fabric (french terry or fleece). Sweatshirts cost 20–40% less to manufacture, are more durable, and better for printing and branding. Sweaters are warmer per gram of fabric weight. This guide breaks down the full differences in construction, warmth, care, and pricing.

What is a Sweater?
A sweater (also called a jumper in the UK and Australia, or a pullover in some markets) is a garment knitted from yarn — wool, cotton, cashmere, acrylic, or blends. The knitting process creates interlocking loops that give sweaters their characteristic stretch, texture, and warmth. Sweaters range from lightweight fine-gauge knits to chunky cable-knit styles.
Most sweaters we produce use cotton or acrylic yarn — both are affordable, hold dye well, and survive regular washing. Wool sweaters trap more warmth per gram than any other option, which is why they dominate cold-weather fashion. Cashmere is the lightest and softest but costs three to five times more than wool, so it stays in premium collections. Acrylic blends give you the wool look at a fraction of the cost, though they do not breathe as well.
What is a Sweatshirt?
A sweatshirt is a garment cut and sewn from looped fleece or french terry fabric. The fabric is produced on a circular knitting machine, then cut into pattern pieces and assembled. Sweatshirts have a smoother exterior surface and a looped or brushed interior for warmth. The construction is the same as t-shirts — just heavier fabric.
Turn a sweatshirt inside out and you will see a completely different texture from the outside — the interior is either looped french terry (for spring/summer weight) or brushed fleece (for fall/winter warmth). This two-sided construction is what separates sweatshirts from sweaters, which look and feel nearly identical on both sides.
How to Tell a Sweater from a Sweatshirt
Not sure which one you are holding? Three quick tests that work every time.
Turn It Inside Out
If the inside looks and feels different from the outside — looped or fleecy — it is a sweatshirt. If both sides look essentially the same, it is a sweater.
The Unravel Test
Cut a small thread on the hem. A sweater will start to unravel because the yarn loops are all interconnected. A sweatshirt will not unravel — the fabric holds together like any woven or knit textile.
Check the Care Label
Sweaters often say 'hand wash' or 'lay flat to dry' because knit structures lose shape in a dryer. Sweatshirts typically say 'machine wash, tumble dry low.' The care instructions reflect the construction difference.
Head-to-Head Comparison
| Factor | Sweater | Sweatshirt |
|---|---|---|
| Construction | Knitted from yarn | Cut-and-sewn from looped fabric |
| Warmth | Higher per gram (air trapped in knit) | Medium (fleece lining adds warmth) |
| Stretch | High (inherent in knit structure) | Low-Medium (depends on fabric blend) |
| Care | Delicate wash, reshape to dry | Machine wash and tumble dry |
| Manufacturing Cost | Higher (slower production, more yarn) | Lower (faster cut-and-sew, cheaper fabric) |
| Printability | Limited (textured surface) | Excellent (smooth surface, all methods) |
| Formality | Smart-casual to business casual | Casual to athleisure |
| Durability | Moderate (prone to pilling and snagging) | High (withstands frequent washing) |
Sweater vs Sweatshirt vs Hoodie
A hoodie is a sweatshirt with a hood sewn onto the neckline. It uses the same cut-and-sew construction and the same french terry or fleece fabric. Every hoodie is a sweatshirt, but not every sweatshirt is a hoodie — crewneck sweatshirts and quarter-zip sweatshirts have no hood.
A sweater with a hood is technically possible but rare. When brands do make hooded sweaters, they are still knitted from yarn and have all the properties of a sweater (stretchier, harder to print on, different interior texture). If you see a hooded garment in a store and the inside feels like soft fleece, it is a hoodie (sweatshirt). If the inside looks the same as the outside with visible knit texture, it is a hooded sweater.
When to Choose Each
Choose a Sweater When…
You're designing for cold-weather fashion, premium positioning, or markets where natural fibers (wool, cashmere) command a price premium. Sweaters work for high-end retail, gift collections, and heritage brands.
Choose a Sweatshirt When…
You need screen printing, embroidery, or branding. You want lower manufacturing cost, easier care, and broader market appeal. Sweatshirts dominate athleisure, streetwear, team merchandise, and promotional apparel.

Frequently Asked Questions
Is a sweatshirt the same as a hoodie? ▼
No. A hoodie is a type of sweatshirt that has a hood attached. A crewneck sweatshirt has no hood — just a round neckline. Both are made from the same cut-and-sew construction using french terry or fleece.
Are sweaters warmer than sweatshirts? ▼
Generally yes. Knitted sweaters trap more air between the yarn loops, providing better insulation per gram of fabric. However, a heavyweight fleece sweatshirt (380+ gsm) can match or exceed a lightweight sweater in warmth.
Can you screen print on a sweater? ▼
It's possible but not ideal. Sweaters have a textured knit surface that reduces print clarity and durability. Sweatshirts with their smooth french terry exterior produce much cleaner, longer-lasting prints.
Which is cheaper to manufacture — sweaters or sweatshirts? ▼
Sweatshirts are 20–40% cheaper. Cut-and-sew production is faster than knitting, fabric costs less than yarn, and sweatshirt patterns are simpler. This is why promotional and team merchandise uses sweatshirts.
What fabric weight should a sweatshirt be? ▼
280–320 gsm french terry for year-round wear. 320–360 gsm fleece for cold weather. 360–400 gsm heavyweight fleece for premium streetwear. Under 280 gsm feels too thin for most sweatshirt applications.
What is the difference between a jumper and a sweater? ▼
They are the same garment. 'Sweater' is the standard term in American English. 'Jumper' is the standard term in British and Australian English. Both refer to a knitted garment pulled over the head. In British English, 'sweater' is also understood but used less often.
Can you put a sweater in the washing machine? ▼
It depends on the fiber. Acrylic and cotton sweaters can usually handle a gentle machine cycle in cold water. Wool and cashmere sweaters shrink, felt, or lose shape in a washing machine — hand wash or dry clean these. Always check the care label. Sweatshirts, by contrast, are machine-washable by default.
Which lasts longer — a sweater or a sweatshirt? ▼
Sweatshirts generally last longer with regular use. Their cut-and-sew construction resists pilling, stretching, and snagging better than knitted sweaters. A mid-range sweatshirt can handle 100+ wash cycles before showing wear. Sweaters, especially fine-gauge knits, tend to pill and lose shape sooner — though high-quality wool sweaters can last decades with proper care.
