Sleeping Gear
Sleep and rest in the field decide how long you can stay operational. Good sleeping gear decides whether you wake on exercise rested or frozen through. The category gathers sleeping bags, mats, tents, tarps and field beds into one system.
The bag's comfort rating and the mat's insulation must match. The best bag loses to ground that pulls heat out from under you. For year-round use in Estonia, aim for a comfort rating of −5 °C or lower. Pair it with a sleeping mat with R-rating starting from 3. Synthetic fill, used by Snugpak, Carinthia, Mil-Tec and others, beats down in a damp climate. Overhead cover comes from tents and tarps. Start from the sleeping bags themselves.
The advice here comes from reservists who pick this gear while being in the forest rather than in meeting rooms.
