Another benefit of the BWB holster it that it is designed to flow naturally with the body creating flexibility at the pivot points resulting in easy wearability and all day comfort.
Holsters that are worn at the waistband and belt, or sometimes even around the shoulders, can often restrict movement causing pinching or rubbing of the skin and general discomfort.
The caveat to this is that the BWB holsters higher level of retention and deep concealment can cause the firearm to be more difficult to retrieve, especially while seated, putting it at a slight disadvantage.
The most popular options of BWB holsters resemble fanny packs or a pouch type of concealment for the firearm.
Because BWB Holsters are designed to be worn below the waistband, under clothing and held close to the body, comfort is important.
