Top professional 'Colossus' Bag constructed from quality cow hide leather. Canvas lined to prevent the leather from stretching and double stitched to increase strength at the joints. Textile filled and machine compressed, this punch bag has been designed and engineered for intense commercial use. Featuring a 25mm inner foam jacket, this delivers a softer more responsive feel to the bag and reduces the impact of shock to your wrist and hands. Able to take the heaviest of punches. The bag is closed with traditional eye-lets and lace while the base has a heavy duty metal D ring giving the option for the bag to be tethered.
