Mountain Hardwear - Lamina Z Spark 34F

Unique Lamina™ construction maximizes the loft of your insulation, eliminates cold spots and thermally maps insulation to areas you need the most warmth. By strategically placing insulation, this bag concentrates warmth where you need it most – around your core and feet. The comfort mummy fit of the Lamina Z Spark 34F offers room to move while remaining thermally efficient. A soft polyester lining wicks away moisture and the lightweight nylon shell repels water. Full-length zipper has double sliders for ventilation.
