Our Verdict

The Haglofs LIM Airak -0 is an ultralight and minimalist sleeping bag designed for warm-weather adventures. Despite its feathery 648g weight, it has an impressive EN comfort limit of 5°C, making it suitable for summer trips.

200g of premium 800 fill power hydrophobic RDS-certified down inside a lightweight Pertex Quantum shell contributes to its warmth. The down’s water-resistant treatment helps maintain insulation performance if the bag gets damp.

The LIM Airak’s thermally efficient mummy cut reduces airspace for your body to heat, while the vertical baffles on the torso and foot box maximise loft and warmth. The anatomically shaped foot box and hood help seal in warmth.

The one-third-length centre zip allows you to stick your arms out while staying cocooned for ventilation. The stretchable waist baffle allows some air circulation to prevent clamminess.

While minimal, the LIM Airak includes features like a draft tube, hanging loops, and a waterproof stuff sack. It strikes an excellent balance of warmth, weight, and packability for ultralight adventuring in mild conditions.
