Tired of cold metal seats in your treestand or want some extra comfort in your climber? The Heated Seat 2.0 is designed to sit on top of most hang-on and ladder stand seats. Keep your seat toasty and warm for four hours straight. The rechargeable lithium battery with dual USB ports also serves as a charging station for your phone. Both the battery and heat source are removable for easy cleaning. The waterproof shell protects internal components, while the no-slip bottom keeps the seat right where you put it.
