What the specs mean
The product name or temperature label is not automatically an ISO comfort rating. The recorded comfort figure is 16°F (-8.9°C); verify the exact size and test method before planning a cold night. Fit also depends on usable internal length, shoulder room and your sleeping position. Pad insulation and weather matter as much as the bag.
Read the exact variant
15F / Regular is the recorded option. Other sizes or revisions may have different dimensions, weight, or test labels.
