The W Lamina -18 from Mountain Hardwear is an excellent mummy sleeping bag with different insulation zones. It has thicker insulation in areas where the body cools down more quickly. The highly compressible filling is laminated to the outer fabric and therefore cannot slip. Damp and cold, wet weather cannot harm the Thermal.Q insulation. The water-repellent outer fabric also prevents condensation from forming inside the tent. And its design is specially tailored to the female body shape. In the cozy W Lamina -18 sleeping bag with a comfort range of minus 12 degrees, you'll be wrapped up warm and cozy even on cold nights.
