Choosing the right 3-season sleeping bag is key to staying comfortable on spring, summer, and autumn adventures. Each sleeping bag or backpacking quilt is given a temperature rating, which helps you gauge its warmth. While the rating in a product’s name offers a general guide, it’s not always the exact tested figure - brands often round to the nearest 0 or 5. For the most accurate idea of performance, check the actual EN/ISO test rating.
A three-season sleeping bag is generally designed to keep you comfortable in temperatures ranging from about -5 °C to +5 °C, making it suitable for spring, summer, and autumn use. While individual comfort can vary depending on whether you’re a naturally warm or cold sleeper, these bags offer a versatile balance of warmth and packability for most conditions outside of extreme winter cold. In comparison, four-season sleeping bags are built for harsher conditions, with comfort ratings typically between -5 °C and -15 °C.
Look for two key figures:
1. Comfort Rating - The lowest temperature at which you can expect to sleep comfortably. Match this to the coldest conditions you expect on your trip.
2. Lower Limit Rating - The temperature at which the bag will keep a warm sleeper comfortable. If you’re prone to feeling the cold or anticipate temperatures dipping below average, opt for a bag with a lower comfort or limit rating.
From ultralight down-filled models for fast-and-light backpacking to synthetic options that handle damp conditions, our 3-season range is designed to keep you warm without adding unnecessary bulk to your pack.
