Custom Heavyweight Crewneck Sweatshirt Manufacturer

A crewneck has nowhere to hide. No hood, no pocket, no zip: just fabric, rib and a collar. Light fleece and a thin collar make it a gym sweatshirt. Heavy fleece and a deep rib make it a premium streetwear piece.

Mike Apparel manufactures heavyweight crewneck sweatshirts in 400 to 500 GSM brushed cotton fleece with a wide 2×2 rib collar, V-insert or plain neck, deep rib cuffs and hem, and raglan or set-in sleeves, on regular, oversized or boxy blocks. For brands searching for a custom heavyweight crewneck sweatshirt manufacturer that treats a 50-piece order like a real order, Mike Apparel samples first, produces in 2–3 weeks and delivers duties-paid.

Choosing the cloth for a custom crewneck

Every crewneck programme starts with a swatch card. These are the constructions we recommend for crewnecks; any of them can be dyed to Pantone and most can be washed or garment-dyed after sewing. On this product the two fabrics we quote most are 400 GSM brushed fleece (the heavyweight crewneck standard) and 450–500 GSM ultra-heavy fleece (maximum weight crewneck).

Heavyweight Crewneck Sweatshirt fits we build

We build the pattern on one of the blocks below or from your own measurements, grade it across XS to 3XL for the US market, and confirm every size on the sample before cutting bulk. For a heavyweight crewneck sweatshirt, we usually sample the oversized heavyweight crewneck first and adjust from there.

• Oversized heavyweight crewneck
• Boxy crewneck
• Regular crewneck
• Cropped crewneck

What is inside the seams

The stitch, rib, thread and hardware choices below are what separate a factory crewneck from a promotional blank. All are standard on our runs. Start your heavyweight crewneck sweatshirt tech pack with this line: 2×2 rib collar 3–4 cm with optional V-insert.

• 2×2 rib collar 3–4 cm with optional V-insert
• 8 cm rib cuff and hem with 5% spandex
• Set-in sleeves for oversized, raglan for regular
• Heavier thread and 4-thread overlock
• Bar tacks at side seam ends and collar

Printing, embroidery and finishing

Print, embroidery and wash are done in-house, so the crewneck and its decoration ship as one finished product with one point of responsibility. On a heavyweight crewneck sweatshirt the most common request is centre-chest puff or chenille embroidery.

• Centre-chest puff or chenille embroidery
• Full-back screen prints
• Sleeve prints
• Acid, stone and vintage washes
• Garment dye

Your label on every crewneck

Private label is included, not an upsell. A custom crewneck from Mike Apparel ships with your woven or printed neck label, size tab, care label and, if you want them, hang tags, custom poly bags and printed boxes. Send vector artwork and we produce label samples alongside the garment sample. See our private label clothing page for label types, minimums and artwork specs. For heavyweight crewneck sweatshirt orders we recommend a woven neck label plus a printed care label as the minimum; hang tags and premium sweatshirt blank packaging are added at your choice.

MOQ and reorders on crewnecks

The 50-piece minimum applies per design and colour. A bigger order lowers the cost per piece, since fabric buys go further and the line doesn’t have to reset for a second small batch. Reorders on an approved block skip sampling entirely. For reference, a heavyweight crewneck sweatshirt run of 50 pieces in 400 GSM brushed fleece with one embroidery and private labels is a typical starting spec.

What drives the final number is fabric weight, how much decoration is on the piece, and how many you order — we’ll walk you through all of it in your quote. Read how much does it cost to manufacture a hoodie? if you want the detail on cost drivers before you ask. A first heavyweight crewneck sweatshirt run ships DDP, so the number you're quoted is the number that lands at your door, nothing added at customs.

How the order runs

From brief to delivered crewnecks, this is the sequence and the timing. Total time from first enquiry to goods at your door is usually five to six weeks including sampling. A first heavyweight crewneck sweatshirt order usually moves from brief to delivered goods in five to six weeks.

Made for US brands, shipped worldwide

Delivery to the USA is DDP as standard, so the price we quote for a crewneck is the price you pay, landed. Four to seven days by air to Las Vegas, Atlanta or anywhere else in the country; worldwide shipping is available on the same terms. More on streetwear manufacturing for USA brands and DDP shipping. Heavyweight Crewneck Sweatshirt orders to the USA are usually air-freighted; a 50-piece run weighs little enough that air costs only a few dollars per piece more than sea.
