The Snugpak Softie Elite 1 is a lightweight sleeping bag that can fit into even the most space restricted rucksack. It comes equipped with an Expanda Panel System for an additional 5 inches of space when needed and its own sturdy compression stuff sack. The Reflectatherm metalized fabric is specially coated with dots to help reflect and trap heat. Additionally, this ultralight sleeping bag has a Paratex shell and liner for breathable, windproof, water-repellent, and moisture-wicking comfort.
