Heavyweight Defined: Understanding GSM in Heavy Cotton T-Shirts

Before choosing a heavy cotton t-shirt, it helps to know how thickness is measured. GSM, or Grams per Square Metre, and ounces-oz, essentially provide details on how heavy and dense a fabric is; the higher the GSM, the thicker and more durable the shirt will be. This section gives a clear breakdown so you can choose the right weight for your brand or bulk order.

A heavier GSM means richer feel, better structure, and longevity. This is what sets apart your average, everyday tees from the premium thick heavy cotton t-shirts that are really built for quality and long-term use.

BulkBuddy vs. The Competition: The Best Heavyweight T-Shirts Value

Choosing the right supplier matters when quality, price, and reliability impact your brand. Many companies offer heavy cotton t-shirts, but not all deliver true thickness, comfort, and long-term value. Here is how BulkBuddy gives you a stronger return on every bulk order:

We focus on real heavyweight fabrics, trusted sizing, and fair pricing. That means you get premium-grade tees without paying inflated “streetwear brand” costs.

How BulkBuddy Stands Out

• Thicker Than Standard Heavy Cotton Tees

Many well-known brands cap at about 5.3 oz, such as the Gildan 5000. BulkBuddy offers thicker options that start from 6.1 oz and go up to 300 GSM for max-weight premium tees.

• Better Cost-Per-Unit for Bulk Buyers

The more you order, the more you save. Apparel brands, printers and resellers trust us because our bulk pricing allows them to maintain margins while offering superior quality.

• Quality You Can Feel & Customers Remember

Our tees feel rich, solid, and built to last, boosting brand value, repeat sales, and customer satisfaction for those selling their own printed or blank merchandise.

What Customers Say

“You can immediately feel the thickness. After a number of washes, the shape and color still look new. Perfect for our streetwear drops.”

“The weight and softness were just right for printing. Our clients noticed the quality immediately.”

“Best value we have found in the UK for true heavyweight tees. Strong, durable and consistent sizing.”

BulkBuddy wins on value because you get real thickness, top comfort, and pricing that supports the growth of your business.

FAQ

How does fabric weight relate to GSM? 

What does “heavyweight” really mean? Below are some straightforward answers in this FAQ that will help you make your choice with confidence.

What are thick cotton T-shirts called?

This kind of thick cotton T-shirt is also known as a heavyweight T-shirt or heavy cotton tee. They use high-GSM fabric, which feels firm, durable, and more structured compared to the ordinary lightweight tees. Most buyers also refer to them as thick heavy cotton shirts when the material is 200 GSM or higher.

Is a 300 gsm t-shirt heavy?

Yes, a 300 GSM t-shirt is classed as a max heavyweight tee. This is one of the thickest t-shirts available and gives a premium, luxury feel. These are popular for high-end streetwear brands because they feel bold, long-lasting, and hold their shape extremely well.

What t-shirts are thicker?

The thicker T-shirts are obviously those with higher GSM and oz weight. Anything at 200 GSM or above, around 6.0 oz, counts as heavyweight. The tees that reach 250-300 GSM provide the thickest feel. These provide strong structure, better durability, and a premium fit compared to basic 4.5 oz tees.

What are the best heavyweight tees?

The best heavyweight tees use high-quality ring-spun heavy cotton with a minimum of 200 GSM for comfort and long-term durability. Look for shirts that remain soft, hold shape after washing, and support printing. Premium and best heavyweight t-shirts UK options often include 6.1 oz+ fabric for a richer feel.

Is Gildan 5000 heavy cotton?

Yes, the Gildan 5000 is a popular heavy cotton t-shirt weighing about 5.3 oz. It’s a basic heavy feel but at an entry-level price. However, BulkBuddy provides thicker and more durable alternatives for brands wanting a richer, stronger, more premium heavyweight finish.

What GSM is a heavyweight tee?

A typical heavyweight tee starts at 200 GSM, or 6.0 oz, and can go beyond 250 GSM for thicker streetwear styles. If you want a firm, premium, structured feel, always go with 200 GSM+ for true heavyweight quality.
