Sitka's lightest of insulation options, the Women's Kelvin Active Jacket is quiet, comfortable and breathable, designed to be worn from dawn to dusk through all forms of exertion levels. The Kelvin Active Jacket is single-minded in its intent: ultralight, packable and warm. This minimalist mid-layer wraps your upper body in 80g Polartec® Alpha synthetic insulation, delivering highly efficient temperature maintenance even when wet.
Your stalk may continue; there is no longer a need to shed layers to release excess heat. Polartec Alpha Active is a non-migrating lofted fleece insulation that offers superior breathability and moisture management allowing us to construct a garment with a more open face or liner fabric. By keeping moisture vapor moving freely through the fabric it increases overall air exchange and drastically speeds up dry times. This advancement increases thermal adaptability in changing conditions and different phases of physical activity.
Please keep in mind that ALL of the Sitka Women's gear tends to run a little small so we recommend ordering a size up compared to what you typically wear.Features:
