Engineering is full of impossible deadlines, microscopic tolerances, missing site instructions, and people who absolutely should have checked the drawings first.
That’s why CADShirts exists.
Who We Are
CADShirts was founded by a graduate mechanical engineer with over 16 years of planning, scheduling, and on-site experience in the oil and gas fields.
We know what it’s like in the field, and we know that authenticity cannot be faked. Every graphic is drafted with the exact same precision you’d apply to a real-world project, whether you’re detailing a mechanical drawing, calculating a structural load, or optimizing a Primavera P-6 schedule to find negative float.
The Mission
We make premium apparel for the people who actually design, build, and troubleshoot the world. Not the generic, watered-down versions of engineering, but the authentic, highly technical reality of the profession.
For years, the market has been flooded with clichĂ© “Trust Me, I’m an Engineer” shirts designed by people who don’t know a gusset plate from a flange. CADShirts was built to be the alternative. We cover the entire engineering stack: Mechanical design, Civil and Structural surveying, Project Management, Electrical codes, and STEM theory.
An engineer’s analytical obsession doesn’t turn off when they clock out. That is why a massive portion of our catalog is dedicated entirely to the lifestyle—applying concepts like torque, tensile strength, and optimization to the gym, the sports field, and the weekend cycling route.
The Spec Sheet
We believe that just like a perfectly machined component, the physical specifications of your clothing matter. Form and function must align.
That means:
- Clean, vector-based drafting and technical aesthetics.
- Ultra-soft Premium Tees and Heavy-Duty Fleece that actually last.
- Apparel you can comfortably wear to the site, the office, or the gym without feeling like a walking billboard.
The Authentic Engineering Gift
If you aren’t an engineer but you are shopping for one, you have found the right place. Whether you are looking for a graduation gift, celebrating a hard-earned PE exam pass, or searching for a unique retirement present, we offer authentic engineering gifts that they will actually wear and appreciate—no generic novelty items required.
If You Know, You Know
If you’ve ever:
- Mentally reverse-engineered a household appliance just to see why it failed…
- Argued with a project manager about the physical reality of the critical path…
- Calculated a safety margin or a hazard radius before anyone actually asked you to…
- Turned a weekend hobby, a sport, or a college all-nighter into an unofficial engineering problem…
- Or genuinely laughed at a terrible physics pun…
…you are exactly where you belong.
