What does fabric weight mean?

The weight of a fabric is usually given in grams per square metre (GSM). When it comes to t-shirts, this number can change how it feels, how long it lasts, and how well it fits. In general, lighter fabrics are thinner and let more air pass through them. Heavier fabrics, on the other hand, tend to be stronger, warmer, and last longer.

It's important to know about these differences in fabric weight when you're shopping for t-shirts. A light t-shirt might be great for summer, while a heavy t-shirt will keep you warm in the autumn and winter. Sustainable fashion brands are starting to offer a wider range of t-shirt weights to meet the needs of environmentally aware customers. 

This guide will explain what each fabric weight means, why choosing eco-friendly options is better, and how you can build your perfect eco-friendly outfit.

Lightweight T-Shirts (90 GSM - 150 GSM)

T-shirts that are light are usually made from fabric that weighs between 90 and 150 GSM. People love these t-shirts because they are light and airy, which makes them great for hot weather or for layering under other clothes. The fabric is very light, so these tees are comfortable even on the hottest days, and they dry quickly after being washed.

Benefits:

• Breathability: These t-shirts are great for summer or hot weather because they let your skin cool down naturally.

• Comfort: The lighter fabric feels soft and loose, so it's great for lounging or going on casual trips.

• Flexibility: You can wear lightweight t-shirts with almost anything in your wardrobe, like shorts, skirts, jeans and more. This makes them very versatile.

When to wear:

• Hot weather: They're most comfortable in warm to hot weather because they're not as heavy as thicker fabrics.

• For layering: Lightweight t-shirts are great for layering under sweaters, coats, or over shirts because they aren’t bulky.

• Because they let air pass through, they're also great for activewear and relaxed sports like yoga.

Middleweight T-Shirts (150 GSM - 200 GSM)

Middleweight t-shirts tend to range from 150 to 200 GSM. These are great for people who want ease and structure at the same time. When compared to lightweight fabrics, middleweight fabrics feel a little thicker and more solid without being too heavy. There is a good mix between breathability and warmth, which makes them wearable all year. 

Benefits:

• Durability: Most of the time, middleweight fabrics last longer than lightweight ones and maintain their softness and comfort wash after wash. 

• Structure and fit: These t-shirts keep their shape better, which can be great if you want to look more put-together without giving up comfort.

• Wear during any season: You can wear these tees during any season. In the cooler months, they keep you just warm enough, and in the summer, they're not too heavy.

When to wear: 

• All year long: In the spring and summer, you can wear them by themselves, and in the winter, you can wear them under a jacket.

• Work or casual setting: Because of how they're made, they're great for both casual office settings and get-togethers on the weekends.

• A little cooler: T-shirts in the middleweight range are great for when it's a little cooler outside but not cold enough to need a jumper or jacket.

Heavyweight T-Shirts (200 GSM and above)

Weighty t-shirts are usually 200 GSM or more and are thicker and more solid. These tops are made to last, keep you warm, and keep their shape. Fabrics that are heavier have a unique feel. They feel solid, and they tend to be stiffer at first. However, after several washes, they soften up. Most of the time, clothes of this weight are of good quality and will last for years, even with normal wear and tear.

Benefits:

• Durability: Heavy materials are made to last. The solid construction makes them perfect for long-term wear, and they can handle being washed often.

• Warmth and insulation: T-shirts that are heavier keep you warmer, which makes them great for cooler weather or evenings when it's cold. This kind of clothing keeps you warm, especially when worn under other clothes.

• Higher quality feel: The thick fabric gives a high-end feel that many people associate with more expensive, long-lasting t-shirts.

When to wear:

• Heavyweight t-shirts keep you warm, so you can wear them in the autumn, winter and early spring.

• A heavyweight t-shirt is the best choice for activities that need tough clothing, like camping or working outside.

• Style statement: A lot of heavyweight t-shirts have big prints, drawings, or logos on them, which makes them a popular choice for people who want to make a fashion statement with their clothes.

Options for eco-friendly fabrics in all weights

Now more than ever, sustainability is crucial, so it's important to think about how the clothes we wear affect the world. Lucky for us, there are lots of choices in all weight ranges that support environmentally friendly practices. These eco-friendly materials are often used to make light, medium, and heavyweight t-shirts:

• Organic Cotton: Organic cotton is grown without using dangerous pesticides or synthetic fertilisers. It is a key ingredient in making eco-friendly t-shirts. It comes in different weights and is soft and flexible.

• Recycled Polyester: Recycled polyester is better for the planet than virgin polyester because it is often made from used plastic. Because it's long-lasting, light, and moisture-wicking, it’s a popular choice for activewear.

• Hemp: Hemp is one of the most eco-friendly fabrics because it lasts a long time, breaks down naturally, and grows with little water and chemicals.

• Bamboo: Bamboo is eco-friendly, breathes well, and kills germs naturally. It is a great choice for t-shirts because it is light and airy.

Choosing the right t-shirt weight for you

When looking for the right t-shirt, fabric weight is one of the most important things to think about. It determines how the t-shirt will feel, fit, and work in your wardrobe. For hot weather, lightweight tees let air flow through, middleweight shirts can be worn all year round, and heavyweight tees are durable and warm for cooler regions or long-term use.

But no matter what weight you pick, you should always think about how the fabric will affect the Earth. You can make choices that are good for the environment by choosing clothes made of organic cotton, recycled polyester, and hemp. 

In the end, learning what makes each fabric different is the first step in building a wardrobe that is eco-friendly, comfortable, and stylish. Now that you have this guide, you can find the right t-shirt weight for you and feel good about the choices you're making for the environment and your wardrobe
