What Does Sleeping Bag Season Rating Mean?
Sleeping bag "season" ratings (1 to 4, often shown as a range like "3-4 season") indicate the temperature range a bag is designed for — 1-season bags suit warm summer nights only, while 4-season bags are built for winter camping in near-freezing conditions. A "3-4 season" bag is the most common all-rounder for UK camping, comfortable from roughly spring through autumn.
