Filled with 800-fill hydrophobic down insulation, it achieves an excellent warmth-to-weight ratio. On the front, zipped Thermo Gills help regulate body temperature throughout the night.Constructed with Nemo\'s ultralight Spoon shape: extra room at the elbows and knees ensure side-sleeping comfort. A tapered core and sculpted foot box minimise bulk to give an ideal fit with no wasted space.
