Water Resistance: Synthetic insulation retains warmth when wet and dries quickly.
Affordability: Generally, synthetic insulated jackets are more affordable than down jackets.
Warmth
Down Insulation Warmth
Down is renowned for its ability to provide superior warmth. The insulating power of down is measured in fill power, which ranges from around 300 to over 900. Higher fill power indicates better insulation efficiency and higher quality down. For example, 900fill down provides more warmth per ounce than 600fill down.
Pros:
Exceptional warmthtoweight ratio.
High fill power down provides significant warmth.
Cons:
Loses insulating properties when wet.
Synthetic Insulation Warmth
Synthetic insulation, while not as efficient as highquality down, still provides substantial warmth. Modern synthetic insulations, like PrimaLoft and Thinsulate, are designed to offer improved warmth and performance.
Pros:
Provides reliable warmth, even when wet.
Suitable for damp and wet conditions.
Cons:
Heavier and bulkier than down for the same level of warmth.
