Our Verdict

The Mountain Equipment Klimatic I Synthetic Sleeping Bag is an environmentally conscious choice for summer adventurers and hut-to-hut hikers. This lightweight bag, weighing 749g for the regular size, offers a good balance of comfort and eco-friendly design.

Temperature-wise, the Klimatic I is tailored for warmer conditions. With a comfort rating of 10°C and a comfort limit of 6°C, it’s well-suited for summer camping trips. 

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

The Alpine fit, anatomically shaped hood, and foot box maximise thermal efficiency, while the full-length zip baffle helps prevent heat loss. At 26cm x 18cm x 17cm, it’s reasonably compact for a synthetic bag.

While not as compressible as down alternatives, the Klimatic I offers reliable insulation even in damp conditions—a key advantage of synthetic fill. It’s ideal for summer backpackers who prioritise sustainability and versatility in mild to cool conditions.
