For more complex trips waterproof should be higher - not less than 3000mm in / sec. Water-resistant bottom of the tent is calculated slightly different method. This is due to the fact that even a strong wind and rain did not have a direct impact on the bottom of the fabric. Pressure on the bottom is inside the tent, first and foremost human beings. It is therefore very important to know that with what force acts. In practice, the load on the bottom of the tent at the critical points looks like this: * a person in a reclining position - up to 1000mm / s * a man in a sitting position - up to 2000mm / s * standing upright people - up to 5000mm / s; * A person standing on my knees - up to 6000 V / s, * a man who leaned on his elbow - up to 10000mm in / sec. Go to the bottom of the tent more demanding. This is due to the fact that the flowing outer tent can be more than a cover, but flowing bottom can not be helped.
Therefore, in simple hikes can use waterproof tent floor to 4000mm i / c, but in difficult hikes tent with waterproof floor below 7000mm B / C use is not desirable. As already mentioned, the bottom of the tent is often made of more durable fabric such as Oxford, but at the cost options for the bottom is made of reinforced polyethylene (similar to the material checked bags). This is a very durable fabric with a high level waterproof (10000mm / c), but quite heavy. The weak point of any tents are seams. Due to the fact that the polyamide and polyester fabrics are prone to divergence at the seams with stretch, their special double stitch line and additionally glued (boil). Sometimes in order to stitch the tent using special threads that swell when wet, thus blocking the path of moisture. Type of sealing joints is rarely indicated in description of the tent, but virtually all manufacturers 'normal' tents are paying this much attention. Apart from the type material and impregnation, as well as water resistance, in the description indicate the type of tent used by the thread.
The main indicator of the thread - its thickness, which is measured in the Den (D). In addition to describing the tents are often indicated the density of weaving, which is measured in Tex (T). Knot density is indicated based on the number of woven threads per square inch. And finally, try to understand the description of the upper canopy of one of the Tent: 50D 210T rs Polyamide Si 4000mm. In this case: * 50D - thickness of the yarn; * 210T - weaving density (number of threads per square inch); * rs (RipStop) - woven into a strong thread to enhance tissue * pa - tissue type; * Si - Silicone impregnation; * 4000mm - waterproof at 4000mm water column. Summing up, I want to say that the producers are trying Tent maintain the proportions between the characteristics of tents and terrain of its use. Where weight is important equipment used lighter materials with a reasonable tensile strength. The cost of these tents sometimes seems too high, but here in the first place there is the reliability and practicality. Where the weight of the tent is not so important, try to use cheaper (heavier) materials. The producers are trying to successfully balance between the first and second option to fill all the niches of the consumer.
