Tethrd - SBW Heater

Tethrd SBW Heater - Saddle insulation for cold weather.

The SBW Heater is the world's first modular tree saddle insulation system. It attaches to the back of your Tethrd Saddle to keep you warm on those late season hunts, while the convective wind currents work to stay cool during the early season. Designed to block cold convective winds, it helps you stay in the tree longer when temperatures drop, without adding bulk or getting in the way.
