The 1st and 2nd Generation Hot Tube™ will put heat where you want it. Pull out the Hot Tube™ hose and place under jacket or towel to file air space with warmth.
The 2nd Generation Hot Tube™ updated design allows regulation of air flow from wide open to completely off. When not extended Hot Tube™ acts as a traditional adjustable heating vent. Can be integrated into your current Heater Craft heating system.
