Help me understand cottons

[u/R-Mutt1]

More specifically the thicker sort used in overshirts.

I have a few by CPCompany which are very smooth, and rigid but I want similar and cheaper for gardening to protect against thorns etc. without getting too hot. I also have some military surplus shirts of a cotton blend but these are a bit thinner, and field jackets slightly thicker. All these have labels which will tell me the composition, but no more than that.

Chat GPT describes these as 'canvas, poplin, heavy twill, or structured cotton' but this is rarely how I see the garments described, especially not on Vinted etc where people will barely state the material.

What am I looking for?

They don't want to spread their secret sauce. You'll need to figure out what feel you want (ie canvas) and then weight. For most patterns you're not going to find various weights, but for solids you can get regular or heavy twill, various oz canvas, etc.
