lululemon Unveils Ventscape Run Vest With PrimaLoft Insulation

The vest uses a patent-pending combination of insulation and mesh panels. The design is intended to release heat and humidity as a runner’s effort increases, according to lululemon’s announcement.

Leah Yingling, Ultrarunner and lululemon Ambassador, said in the announcement: “Having a single layer I don’t need to pack away is huge”. The company said it tested prototypes for more than 250 hours and over 2,500 kilometres, both in its product innovation laboratory and outdoors.

Athlete contributors included ultrarunner Leah Yingling, middle-distance runner Nikki Hiltz and Formula 1 driver Lewis Hamilton. They tested fit and construction in cold-chamber and outdoor conditions.
