The Rain Ceiling™ can be quickly attached with ventilation on any side. Up to 3 weatherproof vents are possible. In good weather, ventilation can be improved by removing the Rain Ceiling entirely.

The Insect Ceiling™ can be left open to improve ventilation, and to allow insects to fly out the top of the shelter if the door is open. Pulling the draw cord closes the mesh quickly and easily.

Modular Shelters feature multiple full-height doors, with full storm flaps. These can easily be tied back, and provide easy access for you and your gear. Opening 2 doors allows 2 people to pack or unpack at the same time, and also provides full ventilation.

Opening the sidewalls provides quick, weather-protected access to gear. This can be very helpful when cooking or packing in bad weather - just reach in and grab whatever you need, without unzipping the door.
