Tunnel

It has high resistance to winds coming from one direction, but not as good to side winds. 

Due to the very vertical side walls, the usable space inside the tent is larger compared to ridge tents.

Indicates the maximum number of people the tent can accommodate. For a more comfortable camping experience, it is recommended to choose tents with a higher capacity than the number of people who will use it, so there is extra space for comfort and luggage.

It is the pressure limit of millimeters of vertical water column that a square millimeter of the tent's fabric can withstand without being penetrated by water. The higher the number, the greater the tent's resistance to rain.

5000mm

Tents with a waterproof rating above 3000mm withstand storms, as shown in the table. They are used in winter.

Polyester 75D

D stands for Denier and it is a unit of measurement for the thickness of a yarn. A small denier means a fine fiber, while a larger denier means a thicker, more durable fiber. To calculate the Denier of a polyester fiber, a piece 9,000 m long is weighed, and the resulting grams are the Denier of the fiber. Therefore, if a polyester fiber 9,000 m long weighs 210 g, its Denier is 210

The weight of tents is usually referred to as the minimum weight (the combined weight of the fabric and frame), but may not include other accessories in the package such as stakes, carrying bag, ropes, etc.
