The Benchmark name is synonymous with premium quality, pushing the boundaries of bankside comfort and luxury further than ever before. Enter the next generation of Benchmark ThermaTech Heated Sleeping Bags. Utilising heated elements along the sleeping bags length, with 4 different heat settings to suit all situations and conditions, these bags are suitable for use 365 days of the year. No more shivering on those cold winter nights or getting caught out in adverse conditions. Our unique USB cord enables you to plug the Benchmark ThermaTech Sleeping Bag into your power pack and heat the elements within the bag, offering unrivalled comfort even in the coldest of conditions. Unlike most 5-season sleeping bags that are bulky and heavy with many layers, thanks to the heating system used, the Benchmark ThermaTech Heated Sleeping Bag is up to 50% more compact than some other 5 season sleeping bags on the market today.
