Overview

Built as a low-bulk base layer, this heated shirt is designed to add warmth without getting in the way of layering. It offers three levels of on-demand heat with simple one-button control, powered by a built-in USB cable and a compatible 5V/2A battery or power bank sold separately. The merino wool construction is paired with odor-control and antibacterial treatments, making it a practical choice for hunters who want a base layer that can be worn normally and then turned up when temperatures drop.

Pros

  • Low-bulk heated base layer design wears next to the skin.
  • Three on-demand heat levels offer adjustable comfort in changing conditions.
  • Built-in USB power cable supports use with 5V/2A battery or power bank.
  • Merino wool construction includes Carbon Alloy for odor protection.
  • Silver Alloy treatment helps defend against bacterial growth.
  • Fusix technology adds additional odor adsorption support.

Considerations & Trade-offs

  • Requires a separate 5V/2A battery or power bank, which is not included, so the heating function depends on carrying compatible external power.
  • Designed as a low-bulk base layer worn next to the skin, so it is intended to be layered rather than used as an outer garment.
  • Heat is supplemental and offered in three levels, making it a comfort feature rather than a standalone cold-weather solution.
  • The shirt’s odor-control treatments are helpful for extended wear, but they do not eliminate the need for normal care and washing.
