Synthetic Sleeping Bags
Expert advice on how to choose the best Synthetic Sleeping Bag for your needs. Recommended quality Sleeping Bags from the World's leading brands.

Lightweight sleeping bags with synthetic fillings are less expensive to produce and less prone to losing their insulating properties when wet. Below are four typical fillings used in synthetic lightweight sleeping bags:
- Hollowfibre a collection of Polyester fibres. The most basic but reasonably durable and easy to clean.
- 4 hole Hollowfibre based on the original Hollowfibre but with 4 holes through the centre of each Polyester Fibre instead of one giving a greater surface area to trap warm air and providing more insulation for less bulk and weight.
- Quallofil 7 again a development of Hollowfibre, this material has 7 holes through each fibre, which reduces the weight of the bag further without compromising the level of insulation given.
- Micraloft sometimes called MTI loft, this material is made of very thin siliconised Polyester fibres which are layered up in very fine layers enabling manufacturers to build bags with many warmth giving layers while keeping the weight and bulk of the bag down to an absolute minimum.
