Important Information
The imported title says “30 Degree,” while the description mentions 5°C and “comfort to −1°C”; these do not establish a clear standardized comfort rating. Confirm the exact model and its manufacturer's current ISO/EN rating before planning around a temperature. No fill weight, total weight or dimensions are provided here. Down needs appropriate care and protection from prolonged wet conditions. The imported description uses both “TKI” and “TK1”; confirm the model code before relying on it.
