It’s marketed under the “Tactical Tac-Match Set Combo” variant.

The combo includes front and rear rest bags (i.e. two-piece set) designed for tactical / modern rifles.

It’s pre-filled at the factory (so you don’t have to load it yourself) which saves setup time.

The height is made to clear 30-round magazines, so the front bag is tall enough so that your mag doesn’t interfere with the rest setup.

Material is abrasion-resistant ballistic nylon for durability in field or range use.

The rear bag is designed to be usable in two ways (e.g. for buttstock, or for other supporting positions) to accommodate different firearms.

It is sized / shaped so that tactical / bolt-action rifles benefit from stable support, especially when using high capacity magazines.
