In popular culture, the feedbag is used in the expression strap on the old feedbag, meaning to dine.
When a horse uses a feedbag for the first time, offering it in a hand-held position, without strapping it on, may allow the horse to become accustomed to it.
Essentially, the forage cap, described by some troops as shapeless as a feedbag, was a less-expensive and more comfortable version of the earlier shako with the stiffening removed.
