Quick Answer
Puffy jackets generally provide sufficient insulation for still hunting in moderate temperatures, but may not be adequate for extremely cold conditions or prolonged exposure. They are often designed for mobility and activity rather than static positions. Insulation quality and layering can significantly impact their effectiveness.
Insulation Types and Ratings
When evaluating the insulation quality of a puffy jacket, look for a high fill power rating, typically measured in cubic inches per ounce (ci/in3). High fill power ratings indicate better loft and insulation. For instance, a 700-fill down jacket will provide better insulation than a 500-fill down jacket. Consider jackets with a fill power rating of 700 or higher for still hunting in cold conditions.
Still Hunting and Temperature Considerations
While puffy jackets can provide sufficient insulation, still hunting often requires standing or sitting in a single location for extended periods. In extremely cold temperatures (below 20°F), additional layers or insulating gear may be necessary to maintain body heat. Consider layering a puffy jacket under a windbreaker or shell jacket to enhance insulation and protection from wind. For temperatures between 20°F and 40°F, a well-insulated puffy jacket can be sufficient for still hunting.
Additional Tips for Cold Weather Hunting
To maximize the effectiveness of a puffy jacket in cold weather, use techniques such as breathing into the jacket to warm the insulation, and wear a hat and gloves to prevent heat loss from the head and hands. Additionally, consider using a space blanket or emergency bivvy sack in extreme cold conditions to help retain body heat.
