I'm going to be camping in the second week of November and I will be staying on the south-east coast of England. Should I buy a 4-season sleeping bag, or will a 3-season be warm enough for sleeping in a tent at that time of year? Thanks in advance.
3 season bags are recommended for use in summer, spring and autumn, and obviously 4 seasons are for all four.
I would agree with the other answer, it depends how warm/cold a person you are, but personally I would go for a 4 season.
I used a 3 season one for camping in France and Spain in July this year and one night I ended up in a fleece over my PJs, and that was in a small tent with my boyfriend who I thought would keep me warm!
