The Tempest Advanced 150 Inner Capsule from TRAKKER turns your Tempest Advanced 150 into a twin-skin shelter without the need for additional pegs. The inner capsule is designed to create a fully enclosed living area, with a sewn-in groundsheet that serves to reduce condensation and retain heat at lower temperatures. The inner capsules are perfect for keeping rodents and other unwanted guests out without sacrificing comfort. It is easy to apply with easily recognizable colored center buttons, plus multiple handy internal pockets for receivers, etc. This great addition is made from brushed polyester, which keeps weight to a minimum.
