The Trakker Tempest 200 Skull Cap creates a peak to the front of the Tempest 200, which gives greater protection from the rain without compromising the view of the lake. Not only will the Skull Cap give additional protection from the weather, it also adds a second skin to the top of the shelter to combat condensation and retain heat, and unlike a full overwrap, it can be left in place when the bivvy is packed down.
