“The pro sandbag that I purchased has three inner sleeves that are fillable with whatever you want. I used sand for a 100 lb. bag. The cylinder shape with multiple handles makes it very versatile. My other bags are heavier, but I wanted a lighter one for a longer carry distance. All sandbag work is gruelingly tough and makes one wonder why they like it at all! Get a bag and discover what a real love/hate relationship is all about.”
