Doubled up stitching, a double VELCRO® closure, and 1000D CORDURA® fabric for toughness and durability.

GORUCK Filler Bags come with our Scars Lifetime Guarantee.

Note: Do NOT use as a slam bag, especially on concrete.

Filling Instructions

  1. Fill with sand, dirt, peat gravel, etc., leaving a little bit of room at the top.
  2. Brush sand and debris off the VELCRO® closure with your hand. If it’s stuffed too full and there’s a bunch of sand between the VELCRO® when you try to close it, it would be like trying to close a bottle of Coca-Cola after you shake it up. If the Filler Bag is too full, the VELCRO® can’t work as designed.
  3. VELCRO® both closures shut.
  4. Put it in a GORUCK Sandbag and get to work.

Cleaning and Maintenance

Turn inside out and spray down with a hose and soapy water. This removes sand and debris from the stitching and increases the longevity of your Filler Bags. We designed them to pair with GORUCK Sandbags but they’ll also thrive alone in harsh environments.

Rated 5 out of 5 by from Great quality bags Your filler bags quality is fantastic but if you want feedback from us as a customer - we were sad to see small 20lbs ans 10 lbs fillers go. We understand you don't need those for your events but it's a great product for an average consumer. We are a HIIT gym using small sandbags for our workouts. The 40 lbs fillers are too big for us, we tried purchasing them for our sanbags and they did not work, had to return them. We were lucky to purchase a bunch of 20 lbs and 10 lbs a few years back while you still had them and now we would love to buy more but you dont carry them any more.

Rated 3 out of 5 by from Very durable. Wish it was longer The durability and ruggedness is perfect. I just wish it would be close to the same length as my 80lbs bag. It seems like it's too short. I bought 2 40lbs filler bags to go in my 80lbs sand bag. I put 30 lbs in each and going to work my way up to 80lbs total. One 40 lbs bag is approximately half the length of the 80lbs sang bag. A friend of mine has a competitor's bag and they seem to have a better system as far as the length of the filler bags and how they fit in the sandbag. Maybe it's suppose to be that way. I'm not sure. I will say that with the way it is, it's definitely cumbersome and will whip you on a workout.

Rated 5 out of 5 by from Must with sandbag trainers Sure you could fill your training sandbags with sand directly but you risk fighting sand on zipper teeth to close that thing up, fine particles going into your eyes, losing sand as you slam the sandbag after a satisfying set. How to avoid all this Filler bag. Get one of these baby's fill that with sand and put the filler into your sandbag and viola problems solved. And you wont have to worry about the sand loss as you start building those gains to look like the cadre.
