Blackroll

Completely waterproof, light (~150g), 100% recyclable - "green products" compliant, allergy-free training equipment. The idea is to roll on the floor on this. Improves mobility, stretchability and muscle performance. Opens congestion and improves blood circulation.

The large roll has 3 different hardnesses: med/soft, standard and pro/hard. Suitable for massaging large muscles. Calves, thighs, back, sides, etc.

Mini is ONLY standard hardness (don't let the colors confuse you). Works great for massaging the soles of the feet and the forearms.

Duoball! Two balls attached to each other - Perfect for the long back muscles.
