The Hoverstat Synthetic 7.0 Long is a synthetically insulated sleeping mat that gives high levels of warmth, exceptional comfort and a small pack size. The high quality synthetic insulation creates a barrier between the cold ground and your sleeping bag to prevent conductive heat loss throughout the night. The Hoverstat Synthetic uses a vertical baffle design which helps to keep the insulation in place and evenly across the mat. A self-sealing Gas Mask valve provides a two-way system for inflation and deflation of the mat. This valve helps to prevent air from escaping during the inflation process. Mountain Equipment has developed the Gas Mask valve design to make it easier to use and each part is easily identifiable. The mat comes with a Windsock for inflation and deflation. The Windsock is specially developed by Mountain Equipment for rapid, easy inflation using minimal accessories .The Windsock also helps prevent moisture from getting inside the mat to avoid impacting the thermal efficiency.
