“Yes, I Want The Long Explanation” — Unisex Crewneck Sweatshirt

Classic relaxed unisex fit with ribbed collar, cuffs and waistband. Cotton-rich fleece with a soft brushed inside, about 8.4 oz/yd² (285 g/m²); the exact blend can vary by colour.

Design story & product details

A huge ring-shaped reactor chamber, wrapped in copper coils and packed with blue pipes, rises around a ribbed central column, and one small visitor in a cap and backpack leans on the railing to take it all in. The lettering speaks for them: Yes, I want the long explanation.

That’s the joke and the compliment, aimed at anyone who asks follow-up questions. The fine engraved hatching on the copper bands is what makes this sweatshirt worth owning. It suits the science teacher who never gives the short answer.
