The Air necklace is an ultra-light version of PHITEN®'s trademark necklace, conceptualized and tested by world-class marathon runners asking for something lighter to reduce necklace bounce. The titanium silica foam core cuts overall weight; the fabric shell is a mixture of highly elastic polyurethane and nylon, which allows for a claspless design that stretches effortlessly over the head.

Very lightweight as well as flexible in order to not snap or break from stretching. Solid color to match wardrobe, and an essential tool to any athletes workout.
