In addition to 100g of toasty Microtemp insulation, this very pretty puffy coat employs our patented thermal reflective technology, which reflects your body heat for warmth while maintaining a high level of breathability. The Shimmer Me Jacket's sleek, slightly shimmery shell fabric is water resistant to keep you dry and the traditional down-style baffling is jazzed up with fun ruching on the upper torso and cuffs.
