It depends on the specific model's insulation class and wind resistance. A 'cold'-rated convertible with windproof face panels can handle temperatures down to about -15°C comfortably with the panel up. For sustained temperatures below -20°C, look for an 'extreme cold'-rated convertible with windproof membranes and extended neck coverage, or consider a dedicated extreme-cold full-face balaclava instead.
