OPERATION EXODUS

THE ISSUE:

Based Gym-wear is almost extinct now-days in an industry swamped with corporate-cringe (Gymshart, Dorksport)
Hollow Slogans & Soulless Designs. Many brands try but all fail miserably in the one area that truly matters: Being Based.

THE SOLUTION?

SUNDAY MASS

As authentic & underground as it gets -
This is a one-man operation.
A brand concieved in a garage-gym in the centre of Australia.
Founded in 2021, this is the original. Often imitated, never duplicated
