Engineer a Better Wardrobe.

You live in the lab, you speak the language of components, and you know your Maxwell's equations (that subtle V·B=0 is for you!). Now you can finally look the part without compromising professionalism. We’ve got polos with distinct Ground and Circuit Tree symbols, shirts for the theory-conscious, classic 555 timer hats for the builders, and ties that add just the right amount of geek-chic to a suit.

Finish your professional look with our unique accessories: resistor color-code socks and mugs that keep you powered, plus the most functional Smith Chart spiral-bound notebook on the market.

Don't Let Your Style Flatline.
