Product details:
The ALTOS-S 0F Ultralight Mummy Sleeping bag features down-like synthetic Spectrum S insulation that is made from natural and recycled materials and creates a sustainable finished product with less waste and pollutants. The shell and liner are made from comfortable smart fabrics that keep you warm and are still lightweight and compressible. It will pack down small for stowing in your backpack, but provides more shoulder and leg room than the standard mummy bag.
