First Lite Men's Core Insulated Jacket - Specter

Tailored for mid to late season, the Core Insulated Jacket is the centerpiece of First Lite’s whitetail system. Windproof, quiet, and purpose-built around KitLink™ pass-thru magnetic pockets, it integrates seamlessly with the Core Vest and the Bib’s fleece-lined muff so your hands and essentials stay warm without breaking concealment. When northern winds arrive and mornings turn frosty, this jacket keeps you in the stand longer.

The Core combines PrimaLoft® Gold insulation with a durable, DWR-treated shell and a soft micro-fleece liner. Insulation is mapped with 80 gsm in the body and 60 gsm in the sleeves for efficient warmth that still allows clean draws and easy layering. Wear it as your primary outer in the 20–45°F window, or stack it with the rest of the Core Kit when temps really dip.
