Heated Merino Wool Top - Women
The Fieldsheer Heated Merino Wool Top is a technical heated base layer designed to provide dependable warmth and comfort in cold-weather conditions. Combining natural merino wool with integrated heating technology, it delivers breathable insulation and consistent core warmth for prolonged outdoor use.
Designed to be worn either as a next-to-skin base layer beneath outerwear or as a standalone top in milder conditions, it offers exceptional versatility across changing environments. Merino wool provides natural temperature regulation, breathability, anti-static properties, and moisture management to help keep you warm, dry, and comfortable throughout the day.
Multi-zone heating elements across the chest and back provide even warmth where it is needed most, while the rechargeable 7.4V Powersheer™ lithium-ion battery delivers up to 10 hours of heat on a single charge, depending on the selected setting.
