The Softie 9 Equinox is a multi-functional, three-season sleeping bag that can be easily increased to a four-season bag by adding a Snugpak liner. This is also one of our incredibly lightweight, micro-size packs making it the ultimate easy carrier. The Softie Premier filling has great insulating properties, trapping heat and maximizing comfort. The anti-snag zip has a full-length baffle; the mummy-style shape is designed for warmth and comfort and the quilted, snugfit hood has an adjustable cord all of which ensure a comfortable night’s sleep, even when the temperature drops.
