# 20 Squared | No. 400, Unisex Pullover Hoodie

The weight of No. 400 finds its most grounded expression in the structure of our pullover hoodie. Using clean paint brush lines, the "20 squared" equation is elevated from a simple calculation to a piece of visual poetry. The bold red accent cuts through the deep black ink, creating a focal point that is both warm and intellectually sharp. It is a heavy-weight tribute to a milestone that was reached one day at a time.  
  
A sanctuary of logic. The comfort of a total sum reached through persistence.
