Jammit all-weather target backer Weather-resistant polypropylene Will not tear, wilt or soften in wet/humid conditions Tape, staple or tack targets to backer Good for thousands of rounds Fits the Jammit compact target stand (MTM-CGJMCTS40) 17.5x23x.2 You'll need something to back your targets on the Jammit target stand, and this is the perfect backer. You could use cardboard, but that gets shot up pretty easily, starts to bend/fold in wet or humid conditions, and probably has to be cut to fit the Jammit target stand. With the all-weather backer, just open the package, insert in the stand, attach your target and commence to shootin'!
