Any advice from those that camp a lot. If -7C is the lowest temperature to encounter, the average is -2C, and can be up to 5C, then what rating should I get? Plan for the worst so a -7 or -10 bag? Or double that number? I'll have a good pad and be in a tent. Can also wear more clothing I suppose e.g., toque if needed. The worst is being cold. Spring trout fishing likely have the most experience. Thanks
