The Catalyst 3-season down sleeping bag is designed for Blacks’ in-house range Technicals. It’s not a bad price, and the bag is a nice, simple design, with good fill power. All the necessary features are present, including a baffle that can be sealed around the neck plus one either side of the zip for maximum draught exclusion. The fabric on the baffles is protected from snagging by strips of tape, and as a result the zip runs fairly easily. Inside there is a good-sized zipped pocket, perfect for keeping essentials close by at night. Attempts have also been made to solve a few issues such as static, through careful choice of fabric. Basically this bag is a good all-rounder. But the anti-static and DWR treatments on the inner fabric make it feel odd against the skin. The fit is also a little vague, with the hood and body of the bag feeling really roomy. It also has the worst stuffsack here. Lab testing showed the bag to be nowhere near as warm as the maker suggests.
