Size Guide
Columbia Jacket Size Guide
How to Measure for the Size Guide Below:

A - Length: Place the end of a tape measure beside the collar at the top of the jacket (Highest Point Shoulder), then pull the tape measure to the bottom of the jacket.
B - Width: Place the end of a tape measure at the seam under the sleeve, then pull the tape measure across the jacket to the seam under the opposite sleeve.
C - Sleeve Length: Place the end of the tape measure at the center back of the collar, then pull the tape measure along the top seam of the sleeve. When you get to the shoulder, hold the tape measure in place at the shoulder, then continue to pull the tape measure down the sleeve until you reach the end of the sleeve (The Hem).

Was this designed by AI?
Nope. This wasn't designed/made by AI, and never will.
While we believe at the end of the day AI is just a tool, and can be very useful at times, when it comes to creativity AI can't replace it.
So finding out this shirt was designed by a human either made you feel better or worse.
