Turn your Tempest Advanced 150 into a twin-skin shelter without the need for extra pegs. The inner capsule has been designed to create a fully enclosed inner living quarter, with stitched-in groundsheet which serves to reduce condensation and retain heat in cooler temperatures. The inner capsules are perfect for keeping out rodents and any other unwanted guests without compromising on comfort. It is simple to fit with easy-to-identify coloured central toggles, plus multiple handy internal pockets for receivers, etc. This great addition is manufactured from brushed polyester, which keeps weight to a minimum.
