Replace the filler bags in your REP Sandbags with these Sandbag Fillers. Replacement bags come in two sizes, to allow you to adjust the weight of your sandbag. The medium bag holds up to 25lbs of sand, and the large bag holds up to 50lbs. The bags are incredibly secure, with double hook and loop enclosures to make sure the sand stays inside. The Sandbag Filler Bags are durable and made from 100% synthetic nylon that is resistant to tears and bursting.

REP Fitness sandbags are ideal for Strongman, functional training, and odd-object challenges. Sandbags themselves come in four sizes, from small to XL, are water-resistant, quick-drying, and come in seven colors. The filler bags inside are held in place by high-quality YKK Zippers. Note: Don’t fill the filler bags more than ¾ full to reduce the risk of the bag opening during use.
