The Born Primitive Quiver Grid Fleece Thermal Top is a core piece in the Quiver base layer system—engineered to provide dependable warmth, breathability, and moisture management across changing conditions. Designed for high-output movement and cold-weather layering, this thermal top balances insulation with airflow so you stay comfortable whether you’re climbing, hiking, or stationary in the field.

Constructed with advanced gridTEK technology, the fully synthetic fabric features a grid-patterned fleece interior that traps warm air while channeling moisture away from the body. The result is efficient thermal retention without excess bulk, helping maintain mobility and reducing overall weight. Its streamlined, athletic profile allows it to function equally well as a stand-alone top in mild weather or as a performance base layer beneath mid and outer shells in extreme cold.

Lightweight, packable, and built for repeated wear, the Quiver Grid Fleece Thermal Top is a versatile layer that adapts to your pace and your environment.
