Down is a more efficient insulator than synthetic materials, which is why it is used to create the lightest sleeping bags. But down becomes less efficient than synthetic insulation when wet. To overcome this drawback, a water-resistant outer fabric called Drilite Loft is used by Mountain Equipment on the Snowline. This means you don’t have to be so concerned about tent condensation or snow coming into contact with the bag as it won’t reduce its ability to keep you warm. The bag also features an EXL elasticated lining that causes the bag to hug the body to trap air next to the skin and thereby increase efficiency. The down is held in a combination of V-baffles, box wall and slant wall baffles to make sure the down remains in place to reduce cold spots. The Mountain Equipment Snowline may not be the lightest option, but it provides supreme performance over a wider range of conditions due to its extra features.
