Are you buying a new mummy 3 season sleeping bag? Here are some things we think that you should know. 3 season sleeping bags have enough insulation for colder weather camping trips in spring through to autumn, which provides you with the comfort and warmth you need for taking on almost every season of the year. Keeping you warm in most conditions except for snow, they are extremely versatile and will provide you with the insulation you need, unless you're planning on going on an alpine winter expedition. They weigh less than rectangular bags, so you won't have to sacrifice some warmth for weight. Ideal for cold weather, they help trap body heat. However, these sleeping bags provide less space to move around, making them less suitable for sleepers who toss and turn.
