## About
Enter the coldest night temperature you expect, whether you sleep warm or cold, and whether weight matters. The planner tells you what comfort rating to look for in a sleeping bag, how much insulation (R-value) the mat needs, how to split a weight limit between items and what extras help. Ratings are guidance based on common standards (EN/ISO 23537), so check the label and add a margin if you tend to feel the cold.

## How to use
1. Enter your values in the fields above.
2. The result updates automatically as you type.
3. Copy or note the figures you need.

## FAQ
**Which rating should I use: comfort, limit or extreme?** Use the comfort rating for the temperature you expect. Limit is the lowest temperature a cold-tolerant person can sleep without shivering, and extreme is a survival rating, not for a good night's sleep.

**What is R-value?** A measure of how well a sleeping mat resists heat loss to the ground. Higher is warmer. Roughly 2 for summer, 3 to 4 for three seasons and 5 or more for winter.

**Is the Camping Sleep Kit Planner free?** Yes, with no sign-up or limits.
