Some things are said clearly.
Some things arrive… incomplete.
This light-edition Signal Loss tee captures that familiar moment when sound reaches you, but meaning doesn’t quite make the journey. Rendered in subtitle-style typography and softened tones, it keeps the message readable without shouting.
Designed for clarity, restraint, and quiet recognition — not explanation.
Because different doesn’t mean broken.
Department of Mental Mechanics – Est. 1885.
This t-shirt is everything you've dreamed of and more. It feels soft and lightweight, with the right amount of stretch. It's comfortable and flattering for all.
• 100% combed and ring-spun cotton (Heather colors contain polyester)
• Fabric weight: 4.2 oz./yd.² (142 g/m²)
• Pre-shrunk fabric
• Side-seamed construction
• Shoulder-to-shoulder taping
• Blank product sourced from Nicaragua, Mexico, Honduras, or the US
Disclaimer: The fabric is slightly sheer and may appear see-through, especially in lighter colors or under certain lighting conditions.
This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!
