Synthetic Sleeping Bags

Synthetic insulation is the battle tank of the insulation world. It’s not necessarily the lightest option nor always seen as the most glamorous, but it is without question the most reliable, resilient and the most dependable filling in savage and unpredictable conditions.

There are literally thousands of synthetic insulations out there and whilst not all of them are equal they do share one thing in common.  Everything from the polymer, to the fibre length and diameter, to the method of construction can be customised and developed according to the requirements of its end use, and we have scoured the globe looking for the best synthetic insulations. Ones that will provide durability, consistency, comfort, weather resistance, and of course outstanding warmth.
