Verified Reviews
Exceptional fabric and subtle typography
The drop shoulder is genuinely relaxed and the puff print on the bell is so satisfying to touch. Accurate Pavlov conditioning quote on the inner hem.

Finally merchandise for psychologists that is neither tacky nor condescending. Accurate concepts, heavyweight cotton that survived multiple washes.

Will the screen print crack or fade? expand_more
We use commercial water-based discharge and plastisol printing cured at high temperatures. As long as you wash inside out in cold water, the prints last for years without flaking.
How does the oversized cut fit? expand_more
Our oversized drop-shoulder tees are engineered to hang loosely with wider chest and shoulder dimensions. If you prefer a tailored, regular fit, size down one step.
