Quilts are taking over, and it makes sense: in a sleeping bag, your weight flattens the insulation under your body, rendering it useless. A quilt removes this useless layer, saving weight. The Corus is insulated with fill power 650 Nikwax Hydrophobic Down. Thanks to the hydrophobic treatment, this material is much less prone to losing its insulation if it becomes damp. Note! Unlike with most quilts, the temperature ratings in this product are actually EN standard lab tested. - Long size: for max. 198 cm users - Down fill: 560 grams - Box baffles for great insulation - Snap closure at collar - SynergyLink straps keep the quilt in place on your sleeping pad The down in this product is RDS (Responsible Down Standard) certified.
