The Tri-layer technology was designed to perform in year-round extreme conditions.  In hot, dry conditions, the inside of our Tri-layer tents are actually cooler than temperatures directly in the sun. When it comes to humidity, the most technical fabric in the world is useless if you don’t have good air flow.  All of our tents are designed with oversized doors and windows and both the screens and doors completely open up giving you the airflow needed to keep the tent cool. Additionally, all of our rainflies are coated with a special silver coating.  This coating repels the sun’s rays and gives you a U/V protection factor of 50+.  Last, we’ve designed the tents so that the rainfly doesn’t touch the body of the tent.  By leaving a gap in between the body and the fly prevents the heat from the rainfly affecting the body fabric of the tent.
