What does GSM mean and why is it important?
GSM stands for "grams per square meter" and is the standard method for measuring the weight and density of textiles. The higher the GSM value, the heavier, thicker, and usually warmer and more durable the fabric.
For comparison, standard hoodies on the market typically range from 280-330 GSM, while our models range from 400 to 850 GSM .

Frequently Asked Questions
Why are your hoodies more expensive?
Our hoodies offer a significantly higher GSM (up to 850 vs. 280-330 for standard), double-layer construction, and reinforced seams. This results in a 2-3 times longer lifespan. Over the years, our hoodies are more cost-effective.
Do your hoodies shrink when washed?
All products are pre-washed. When following our care instructions (30°C, no tumble drying), the maximum shrinkage is less than 5%, which is well below the industry average.
Are your products suitable for allergy sufferers?
Yes, all products are certified according to GB 18401-2010 Class B, tested for skin compatibility and freedom from harmful substances, and have a skin-friendly pH value.
