Built for winter conditions and high-altitude adventures, 4-season sleeping bags offer maximum warmth when temperatures plummet. Each sleeping bag or backpacking quilt is given a temperature rating to help you gauge its performance. While the figure in the product name offers a general guide, it’s not always the exact tested value - brands often round to the nearest 0 or 5. For the most accurate reading, check the official EN/ISO test rating.
Focus on two key figures:
-
Comfort Rating – The lowest temperature at which you can expect to sleep comfortably. Match this to the coldest nights you anticipate.
-
Lower Limit Rating – The temperature at which the bag will keep a warm sleeper comfortable. If you’re prone to feeling cold or expect extreme lows, choose a bag with a lower rating for extra margin.
From lightweight alpine-ready down bags to rugged synthetic options for damp winter treks, our 4-season range ensures you can face the cold with confidence.
