Attribute deep dive
We break down what drove each score so you can weigh trade-offs.
Quality Analysis 100/100
This T-shirt is built for the long haul, featuring an exceptionally dense 12.1oz/409gsm Japanese fabric—roughly double the weight of a standard heavyweight tee—and robust Union Special flat side seam construction, ensuring it can withstand a lifetime of wear.
Comfort Assessment 60/100
The comfort score starts low due to the extremely heavy 12.1oz fabric, which is roughly double the weight of a conventional heavyweight tee, suggesting a rigid and potentially restrictive feel. However, the use of Union special flat side seam construction is a positive detail that prevents internal chafing.
Sustainability Impact Not Available
