Overview

The Polyfit 850017268784 is a pair of cast iron dumbbells finished in sky blue. Amazon lists the item weight as 1.5 kilograms, about 3.3 pounds, though it isn't clear whether that covers one dumbbell or the pair.

This sits toward the light end of the dumbbell range, and the bright sky blue finish makes it easy to spot among mixed sets in a home gym. As with the weight ambiguity, buyers who need an exact per-hand number should check the listing directly.
