Sandbag Sand Filler Bag - Inner weight bags for Sandbag Training Workout equipment - Works with all supplier bags - Avai in Three Sizes - XL (45lb max), LG (30lb max), MED (15lb max) - Velcro Sealed

I received my filler bags earlier than expected which was a plus. I haven't filled yet but they seem very well made. I knew the dimensions but was blown away by the size. They will be perfect for my current sandbags.I will definitely buy again when I upgrade my bootcamp equipment.Update: I filled my bags with rubber crumbling. Each bag has been holding up to 35 lbs with no issues. The double velcro enclosure is awesome!Hope these fillers become available again soon. Worth the buy!!

These bags have very strong velcro so the sand stays put even when filled to max capacity. I bought the sand at Home Depot (very cheap). To fill, I placed a plastic bag (with the bottom cut out) inside the filler bag so I wouldn't get sand all over the filler bag. I'm not sure if this is really needed however since the sand dusts off the outside of the bag pretty easily, but I didn't know how messy I would be. I took a plastic cup and filled the bags. When a bag was almost full, I weighed it on my bathroom scale to get them exactly 15, 20, 25 lbs. At max capacity, the bags are nicely full. They fit inside my sandbag (another brand) perfectly. I had measured my sandbag first to make sure they were the same length before ordering.

Got 15 lbs of sand in the first one I tried to fill and the seam split at the bottom. Just opening the second one caused the seam to split near the velcro at the top. Didn't even try to open the third one. These are junk. There is no way that these could be tossed around inside a sand bag without making a mess all over the place. Cheap Chinese garbage.

it is alright for the money. the fine particles of the sand escapes from the seams of the bag and that is why i gave it 3 stars.the filler bags are made with excellent material 1000 denier, but the seams need to be folded and triple stitched(industrial quality stitching) to prevent sand from escaping. a little disappointing. the company should put a little more effort into producing a better quality product.

Great filler bags at a GREAT price!!!

These hold some weight but stitching comes out on velcro and noticeable dusting off of sand internals is annoying. Too dusty to breathe while in use indoor workouts. Using for dead weight in rear of truck now.

Good bags, don't leak, I haven't slammed them yet I mainly use them for ruck weight but so far very decent bags. each 45lb bag can hold more than 45lbs more like 50-60 but I recommend sticking with the prescribed weight for an accurate determination unless you are just going to use them for what I use them for. If so, then load em up yo.

It was easy to fill both the 15 and 30lb bags using a cottage cheese container as a scoop. The tops have two layers of hook-and-loop closures to keep the sand where it belongs. I used sand from the tubes they sell for weighing down the back of a pickup -- so not super fine -- and so far I haven't seen anything sneak out of my heavy bag.
