Robens Icefall Pro 900 £180

+ Value for money, centre zip, down-like performance, good features

- Heavy, bulky, synthetic insulation

The Icefall Pro features synthetic insulation, but you’d be forgiven for thinking this bag is full of lofty, highgrade down. The MicroThermo Ball insulation mimics the performance of down superbly, puffing out into a plump, thick and cosy haven. The interior is luxurious, courtesy of a whopping 900g fill of polyester clusters, and allround warmth is enhanced by a good hood, well-padded neck baffle, two thick zipper baffles, and the box-wall construction. Rated 0°C for comfort, the temperature grade is very realistic and, anecdotally at least, the Icefall Pro 900 feels warmer than some bags with better EN/ ISO ratings. The other striking feature is its central zip, which makes getting in and out easy, facilitates fine-tuned climate control, adds versatility (completely unzip to use like a quilt), and enables you to sit up and use your arms for chores like cooking or gear organisation. Price-wise, it’s a bargain, but there are downsides. It’s the heaviest on test, far from the most compact when packed away, and the synthetic insulation isn’t as premium as down. For beginner campers or price-conscious experts, however, this is an affordable, high-performing choice.

Verdict

A cosily-insulated, fluffy synthetic sleeping bag at a great price – but it’s heavy and bulky.
