The tent contains 2 separate layers, which are placed one on top of the other on its roof or upper part.

Usually, the first layer has waterproofing, while the second is a layer that allows air passage and offers better ventilation in the tent.

The tent features the BlackOut Bedroom system from Coleman, where the entire interior of the tent's room is black. 

This means you can sleep even if the sun is up or at night without being disturbed by the camping lights. Additionally, the black interior keeps the tent a bit cooler in the summer, as it doesn't allow the sun's rays to penetrate the interior of the tent.

T means Thread which refers to fiber, and the number indicates the sum of the vertical and horizontal fibers in a square inch of fabric (see photo). The higher the Thread count, the denser the weave and the greater the fabric's durability.

D means Denier and it is a unit of measurement for the thickness of a thread. A smaller denier means a finer fiber, while a larger denier means a thicker, more durable fiber. To calculate the Denier of a polyester fiber, a piece 9,000 meters long is weighed, and the resulting grams are the Denier of the fiber. Therefore, if a 9,000-meter-long polyester fiber weighs 210 grams, then its Denier is 210.
