There are notable differences between regular pants and Baker Pants. One is the fabric, always make sure your Baker Pant has the HBT. Next are pockets, all Baker Pants have patch pockets, no matter what. As far as color goes, they come in all colors ranging from military olive to white and even black sometimes. Buttons, not all will have the 13 stars, usually only the ones that come in khaki or olive color, some will have regular buttons suits for other purposes but not for the heavy duty use that the 13 star buttons imply.
Now that you know about Baker Pants, what's stopping you from grabbing one yourself? They're fascinating pants with a mix of history behind them. But remember to always go for the higher quality pants for more authenticity, for this we recommend RRL & Co. or, if you prefer, Double RL. It's the same company but said differently, everyone likes to call it something different even just RRL. It's really up to you but remember them first as they are the purveyors of Baker Pants!
