It keeps you warm and is made thoughtfully. However, the processing I trust to no eternity. Compared to my Mount McKinley sleeping bag (same temperature class, now 25 years old) makes this a better impression to lengths (added, was even then a bit more expensive). For example, the velcro, a Fitzelteil which will hardly stop. The surface - so I do not want to get caught on something sharp. Why this sleeping bag has two zippers (one in the foot, one on the side) has not quite revealed to me. But he has met for the first 10 days his job. The value for money I find absolutely appropriate, -subjektiv I find him just only 'OK'.
