This is actually two different types of the same thing. A boffer is a term typically assigned to describe a
homemade LARP safe weapon. In most cases this design has a core of PVC pipe, kite spar, or carbon fiber fitted with tight appropriate pipe foam or suitable layers of cell foam to pad the weapon, then covered with either a cloth based tape, a thin cloth covering, or a thin enclosure of organic polymer. Depending on the experience and talents of the maker it can result in a very professional looking weapon or a PVC pipe wrapped in pipe foam and covered with tape. Latex Weapons refer to mass-made commercial weapons that are preapproved for most LARPs. These, contrary to their name, are not always covered in latex and typically have high detail work in their design. Depending on the price you pay it can look like a crude version of what you want or a life-like replica. In either case the terms, boffer and latex weapon,
are terms used to address the physical LARP safe weapons that players use to represent weapons in-play at a LARP.
