Fjallraven says: 

Comfortable, three-season synthetic sleeping bag for hiking and trekking adventures. Produced without PFAS.

Reliable three-season sleeping bag designed for tall users up to 200 cm, perfect for hiking and trekking adventures. Made from recycled materials that are light on your back as well as your conscience, you are guaranteed to sleep well all night long. Abisko Three Season Long has numerous technical features, including an adjustable hood, internal zippered pocket, a full-length two-way zipper with anti-snag slider and angled footbox, plus an adjustable draft collar and draft tube to stop warm air escaping. The synthetic PrimaLoft® padding is especially developed for sleeping bags and will keep you warm even in damp conditions, and is also durable and easy to care for.

Our Verdict

The Fjällräven Abisko Three Seasons is a roomy, robust sleeping bag that handles cooler nights and damp conditions with confidence. Packed with recycled PrimaLoft insulation and enclosed in a soft yet durable polyamide shell, it’s designed for consistent warmth even when moisture is in the air.

The fit is generous for a mummy bag, particularly around the footbox, and the draft collar and full-length zip with dual sliders allow easy venting or sealing up as needed. With a comfort rating of nearly 1°C and a limit of -5°C, it performs solidly from late spring to early autumn. 

At around 1.5 kg, it’s heavier than its down equivalents, and the packed volume is on the larger side. Still, for those prioritising durability, synthetic performance, and year-round usability, the weight is a fair trade.
