Introduction: Cognitive Load Reduction

Why did Zuckerberg wear the same T-shirt every day? To “Reduce the number of decisions”.

Engineer’s brain resources should be saved for code and architecture. Cut the “Noise” of choosing clothes and always wear the “Optimum”. That is the “Uniformization of Engineers”.

1. The Core Material: Merino Wool

The era of cotton is over. Wool (Merino Wool) is a natural air conditioner and the strongest deodorizing material.

2. The Shell: Gore-Tex Architecture

Outerwear requires “All-weather” specs. Sudden rain, building wind, train air conditioning. Need a “Firewall” to shut out all these.

Arc’teryx Beta AR Jacket

For mountains, but strongest in city life too. 3-layer structure of Gore-Tex Pro does not let water in from outside, but lets moisture out from inside. Even if you have a PC in your backpack, you don’t need an umbrella with this shell.

3. The Bottoms: “ABC” Technology

Do you know the technology with the ridiculous name “Anti-Ball Crushing (ABC)”? Cutting developed by Lululemon that expands the range of motion of the crotch.

Lululemon ABC Classic Fit 5 Pocket Pant

Looks like chinos. But stretches enough to squat. Functionality that does not inhibit blood flow even if sitting at a desk for a long time, and can go to climbing gym as is. This is the “Modern Combat Uniform”.

Conclusion: “Optimize” Yourself

Clothes are cases (chassis) that wrap the hardware called you. If heat exhaust efficiency is bad or it is too heavy, the performance of the CPU (Brain) inside will not come out.

Choose the latest clothes like buying the latest MacBook. Comfort is directly connected to productivity.
