Our Verdict

The Mountain Equipment Klimatic III Synthetic Sleeping Bag is a robust option for backpackers and trekkers venturing into cooler climates and higher altitudes. This eco-conscious bag combines warmth, durability, and environmental responsibility.

Temperature-wise, the Klimatic III is impressive. With a comfort rating of 1°C and a comfort limit of -5°C, it’s well-suited for three-season use in many environments. 

The bag’s standout feature is its sustainability. It utilizes 90% recycled POLARLOFT® insulation and 100% recycled fabrics for both shell and lining, making it an excellent choice for environmentally-minded outdoor enthusiasts.

Weighing 1251g for the regular size, it’s not ultralight but offers an excellent warmth-to-weight ratio for a synthetic bag. The wave layer construction, Alpine fit, and anatomically shaped hood and foot-box maximise thermal efficiency.

While bulkier than down alternatives with a packed size of 37cm x 24cm x 21cm, the Klimatic III provides reliable insulation even in damp conditions – a key advantage of synthetic fill. It’s an ideal choice for backpackers prioritizing versatility and sustainability in cool to cold conditions.
