This listing is for a perfect condition full sleep system from Carinthia that is able to handle the harshest winter or can be scaled down to fit your needs. A defense 4 Outer bag with tropen Inner bag makes this package the best possible pairing. Inside the tropen is the Carinthia sleeping bag liner as well compression bags included, all 3 are in practically new condition but only listed as pre-owned purely for 100% transparency. The bags have been stored outside of their compression sacks to maintain maximum loft. Any questions please do ask and thank you for viewing my listing.
