What is GSM and how do I know which Gi to choose?

Industry Standards: Most top Gi brands (including Gold BJJ and Hayabusa) recommend GSM based on climate, training frequency, and personal feel, making sure customers understand the difference between mobility and durability.

Which Gi Should You Choose?

• 350 GSM: Choose this if you want ultralight and cool gear—perfect for hot gyms and competition weigh-ins.

• 450 GSM: The balanced choice, great overall feel and versatile performance. Fits most athletes’ needs for frequent use.

• 550 GSM: Go heavy for maximum durability, longevity, and less risk of training partners holding strong grips. Feels like “armor” and is perfect for hard rolling or colder environments.
