3 Season Sleeping Bags Buyers Guide
3 season sleeping bags probably have the longest usage range of any season rating. They are suitable for British summers, although may be too hot if the weather gets nice. And they can be used during the Easter period as well as late autumn.
They are not to be recommended for use during the winter, and definitely not in extreme weather conditions in mountainous or arctic areas.
