The
Century Large Hydrocore has a more consistent and superior feel than traditional heavy bags. The durable polyester-backed vinyl shell of the
Hydrocore covers a water core and offers the real sensation of hitting a real opponent. The water core helps in providing a variable weight system training making it more realistic as the bag moves more sporadically (like a real opponent) than normal hanging bags.
The
Century XL Hydrocore is for the hard-hitters and features the same variable weight system with simply a larger and heavier surface area for pure strength training.
