Duofold Expedition Baselayer Thermal Shirt

Features

1. Expedition-Weight 2-Layer Construction — 9.4 oz dual-layer fabric bonds two insulating layers into one for maximum warmth without the bulk of stacking garments.
2. Varitherm Thermal Performance — Engineered baselayer fabric traps body heat in cold conditions while regulating temperature during high-output activity.
3. 96% Polyester / 4% Spandex Blend — Ring-spun polyester face with spandex content delivers 360-degree stretch and a sleek, low-profile fit under outerwear.
4. C Vapor Moisture-Wicking — Pulls sweat off the skin and dries quickly to keep you warm and comfortable when the temperature drops or the pace picks up.
5. Flatlock Seam Construction — Smooth, low-profile seams sit flat against the skin to eliminate chafing and hot spots on long days in the field.
6. Drop-Tail Hem — Extended rear hem stays tucked when you bend, reach, or shoulder a rifle so cold air never sneaks up your back.
7. Odor-Resistant Fabric — Sleek polyester face resists garment odors over multiple wears between washes — useful on multi-day hunts and trips.
8. Crew Neck with Long Sleeves — Classic crew collar layers cleanly under flannels, fleece, and shell jackets with no bulk at the neckline.
9. Full Range of Motion — All-over stretch keeps the shirt moving with you whether you're stalking, glassing, snowshoeing, or working outdoors.
