An IWB holster, or Inside the Waistband holster, is a type of firearm holster designed to be worn inside the waistband of pants or skirts. This design allows for concealed carry, making it easier to hide a firearm from view while still providing quick access when needed. IWB holsters are popular among those who prioritize discretion and comfort. These holsters come in various materials, including leather, Kydex, and nylon, each offering different levels of comfort and retention. Proper fit is essential for safety and ease of use, as an ill-fitting holster can lead to discomfort or accidental discharges.
