Heavyweight Guide
Not every garment feels the same – even if it looks similar at first glance.
A crucial difference lies in the fabric weight. This is indicated in GSM (grams per square meter) and describes how much one square meter of fabric weighs.
Generally, the higher the GSM value, the denser, heavier, and more premium a fabric feels.
220 GSM
Our Heavy Oversize T-Shirts are made from 220 GSM cotton.
This fabric weight offers the ideal balance between comfort, durability, and a premium feel. The fabric drapes cleanly, remains pleasantly breathable, and is perfect for everyday wear.
350 GSM
350 GSM is used for selected hoodies.
The fabric is significantly heavier than classic hoodies and offers a high-quality structure and a comfortable feel, without appearing too bulky.
450 GSM
450 GSM represents our heaviest cotton fabrics.
These hoodies and joggers impress with their particularly dense fabric, a high-quality drape, and the characteristic heavyweight feel.
The higher fabric weight not only ensures an exceptional feel but also high dimensional stability and longevity.
More than just a number
A high GSM value alone does not make a high-quality garment.
Equally crucial are the quality of the cotton, the processing, the construction of the fabric, and careful manufacturing.
That's why we don't view the GSM value as a marketing term, but as a building block of a high-quality product.
Which fabric weight is right?
There is no right or wrong.
220 GSM is ideal for high-quality Heavy Oversize T-Shirts.
350 GSM offers the perfect balance between comfort and weight.
450 GSM is aimed at those who prefer a particularly heavy, high-quality wearing experience.
Ultimately, it's not just the number that decides – but how a garment feels. This is exactly what we at STSL® place particular importance on.
Fabric construction
French Terry & Brushed Fleece
Not all cotton fabrics feel the same. Besides fabric weight, the finishing of the inside plays a crucial role in comfort, warmth, and feel.
French Terry
French Terry has a characteristic loop structure on the inside. This makes the fabric breathable, pleasantly soft, and ideal for everyday wear or warmer temperatures.
Advantages:
– Pleasantly lightweight feel.
– High breathability.
– Ideal for transitional seasons and everyday wear.
– Soft inside without additional brushing.
Brushed Fleece
For Brushed Fleece, the inside of the fabric is brushed. This creates a particularly soft, fluffy surface with higher thermal insulation.
Advantages:
– Particularly soft feel.
– Warmer than French Terry.
– Ideal for cooler days.
– Characteristic heavyweight feel.
Why we use both
At STSL®, we choose the fabric construction to match the respective product.
French Terry is excellent for garments where breathability and everyday suitability are paramount.
Brushed Fleece is used where a particularly soft feel and extra warmth are desired.
Both types of fabric meet different requirements – that's why we decide, depending on the product, which construction is the best choice.
