Thermarest's Luxurylite Cot Warmer significantly reduces heat loss through the bottom of the cot and weighs just a fraction of the cot itself.
Featuring ThermaCapture Radiant Heat Technology, the LuxuryLite Cot Warmer increases the temperature performance of your cot by 5-8C degrees, taking your cot from 1 to 3-season warmth. The thermal reflective lining captures your body's heat and efficiently adds warmth with virtually no added weight or bulk.
The lightweight and packable Cot Warmer easily attaches to the underside of your cot with six elasticised hooks.
Campbeds like Thermarest's Luxurylite Cot have always been around and whilst they are comfortable there has always been an issue with warmth - the fabric the bed is made from has never provided much in the way of insulation. The Cot Warmer addresses this although the claimed 5-8 degrees doesn't seem like much. I think they have gone for a lightweight option that focuses on reflected heat. Another option for your cot is a closed cell foam mat - heavier and certainly much bulkier - but this will add more warmth again.
