TheMorgan 5kg weighted refillable sandbag is designed for the outdoor PT or boots camp trainer. Portability is the main focus of the product since it is easy to transport when not filled.
The 5 kg sand pockets can either be filled on-site or kept pre-filled to carry with you anywhere. These refillable sandbags are a great alternative to dumbbells or kettlebells. They are cheaper, safer and highly functional fitness training tools.
