Fjallraven says:
Three-season technical goose down sleeping bag with optimal weight-to-warmth ratio. Produced without PFAS.
Keb Three Seasons Regular is a technical goose down sleeping bag with a comfortable mummy fit. It is made from high-performance recycled materials and insulated with 700-cuin of high-quality, ethically sourced goose down, making it compact, lightweight and warm all night in the spring, summer and autumn in temperate climates. The construction combines straight and slanted box wall baffles to eliminate cold spots. The bag has an adjustable internal collar, inside zippered pocket and a water-resistant hood and footbox.
Our Verdict
The Keb Three Season Down Sleeping Bag is a solid choice for trekkers who prioritise durability, comfort, and dependable performance over ultralight minimalism. Filled with 700 ethically sourced goose down, it strikes a balance between warmth and packability, making it suitable for spring to autumn use. The comfort rating of 0°C feels realistic, and the shaped baffles and well-fitted draft collar help retain heat without overheating.
The cut is generous for a mummy bag, especially through the footbox, and the recycled polyamide shell manages to feel both soft and reassuringly tough. Venting is simple to control thanks to the two-way zip, which runs smoothly and resists snagging. The water-resistant foot and hood panels are very welcome, especially if you use a single-walled tent.
At 1076g (Regular), it’s not the lightest in its class, but it offers a level of resilience and finish that justifies the weight. A dependable all-rounder with thoughtful construction and excellent temperature control.
