Hi, I was wondering wether I should EDC a sleeping system. The idea is that if I’m staying at a friends house or in the office unplaned that I can sleep with a little more comfort compared to the couch/floor. The only thing that came up so far was the “Sea To Summit Reactor Extreme Sleeping Bag Liner”. (Links appearantly not allowed?). But I read in some reviews that it’s definitely not as good as it is claimed and hardly worth the money. What do you guys EDC for Sleeping?
