Padded Sport's Sleeves(Cliffe)

Padded Sport's Sleeves.

These stretchy, arm-warming, black, and over-sized arm-bands are made of a soft, comfortable material that gently compresses to the wearer's limbs. Each one clings to the arm with a smooth simple band on the inside to keep it from sliding down the arm and maintains a specific temperature in almost any environment to keep your arms from ever being too cold or too hot.

+1 to Agility while worn.
