Arctic Shield Echo Sleeping Bag Liners

Locks heat in. ArcticShield Retain varies the heat level to give you warmth where you need it most, while still allowing you room to move – because it provides less bulk. A warm hunter is quieter, mentally focused, on the hunt longer, and more likely to be successful. Independent laboratory tests have confirmed that ArcticShield Retain captures greater than 90% of body heat, and maintains the 90% heat for a longer period of time than other products on the market. ArcticShield Retain is strategically located throughout the garment keeping you warm and comfortable no matter what level of activity or temperature range you will be hunting in.
