Custom Hoodie Manufacturer – 450 GSM Cotton Fleece, Private Label & OEM

The Oversized Heavyweight Hoodie is built from 450 GSM cotton fleece — roughly double the weight of a standard sweatshirt — so it holds a structured, boxy shape instead of collapsing into itself after a few washes. Cut with dropped shoulders and a crossover hood, it works as both a streetwear staple and the heaviest layer in your rotation.

Why 450 GSM matters

Most hoodies sit between 250 and 320 GSM. At 450 GSM, this oversized heavyweight hoodie is dense enough to keep its shape on the hanger and warm enough to wear on its own through fall and mild winter days. The fleece is garment washed after construction, so it arrives broken-in rather than stiff and boardy.

Fit and sizing: how oversized this hoodie runs

This oversized heavyweight hoodie is cut with dropped shoulders and a roomy body — take your normal size for the intended boxy silhouette, or size down if you want a more standard fit. The 2x2 heavyweight rib at the cuffs and hem holds the volume in the body rather than letting it ride up. Available in S–XXL; the size chart lists chest, sleeve length, body length and drop-shoulder width in centimetres.

Fabric and construction

100% cotton fleece with double-needle stitching at the stress points. A large kangaroo pocket, a double-layer crossover hood with no drawstrings, and an embroidered logo at the chest. The surface is smooth and matte; the cuffs and hem carry a distinct vertical rib.

Available in four colourways: Bone White, Charcoal Grey, Midnight Blue and Sage Green.

Care

• Machine wash cold, inside out, with like colours.
• Tumble dry low, or hang dry.
• Skip the fabric softener — it coats the fleece and flattens the loft.

If you want one oversized heavyweight hoodie that keeps its structure wash after wash, this is it — 450 GSM cotton fleece, cut boxy, built to be worn hard.

Frequently asked questions

What does 450 GSM mean in a hoodie?

GSM stands for grams per square metre — it measures how much fabric weighs per unit of area. Most hoodies are made from 250–320 GSM fleece. This one is 450 GSM, which makes it noticeably denser: it holds a structured shape, blocks wind better, and lasts longer before the fabric starts to pill.

How does the oversized fit run — should I size down?

It is designed as an oversized fit with dropped shoulders, so take your normal size if you want the intended boxy silhouette. If you prefer a closer, more standard fit, size down one. For a genuinely fitted look, size down two — the body and sleeves both carry extra room.

Is this hoodie warm enough for winter?

It is a heavyweight layer, not a parka. At 450 GSM with a double-layer hood, it works as an outer layer through fall and mild winter, and as a mid-layer under a shell in colder conditions. If you run cold and expect to wear it outdoors below freezing, treat it as a mid-layer.

Will it shrink or lose its shape after washing?

The hoodie is garment washed after construction, so it arrives already broken in and is not expected to shrink noticeably. Wash cold and dry low to keep it that way — hot water and high dryer heat are what distort heavyweight fleece.

Is it a men's hoodie or unisex?

The pattern is cut to a men's fit, but the boxy oversized silhouette runs roomy on most body types and is commonly worn as unisex. Use the size chart measurements rather than the label — chest, sleeve, body length and drop-shoulder width are all listed in centimetres.

Does the hood have drawstrings?

No. The hood is a double-layer crossover construction with no drawstrings, which keeps the neckline clean and avoids the hardware that usually breaks first.

How should I wash and dry a 450 GSM cotton fleece hoodie?

Machine wash cold, inside out, with like colours. Tumble dry low or hang dry. Do not use fabric softener — it leaves a coating on cotton fleece that flattens the loft and reduces warmth. Wash it less often than a t-shirt; heavyweight fleece tolerates airing out well.
