Water tightness and transpirability of fabrics

A synthetic shirt in summer, or a k-way jacket on your skin during a cool evening are doubtlessly not the right choices for your well-being. You can easily imagine the degree of humidity that will strike you, even in case of openings in the tent. The quality of a tent's fabric is therefore fundamental in order not to turn a quiet sleep into a sauna nightmare. As a matter of fact, our body continuously produces heat, to such an extent that during the night it loses in average one third of litre of water, in standard rest conditions. For heat and humid air in the tent not to condensate, they shall freely go out from fabric.

Overzone fabric, which is composed of 50% polyester and 50% cotton, is transpirable for air but water tight, as it comes out from the tests carried out in conformity with international regulations commonly recognized (UNI EN ISO 923/97). According to these tests, Overzone fabric has a permeabilty to air equal to 53mm/s- which means it is transpirant!
In conformity with military specifications, each square centimetre of fabric "transpires" in a natural and uniform way, efficiently contrasting humidity, internal condensation and heat. Whether you are sleeping in the desert or under persisting rain, on the Pyrenees, at the equator, or in the Arctic circle, your tent's environment will always be fresh, dry and healthy.

How to check the fabric is breathable

Many fabric suppliers say their fabric is breathable, but to make sure it is, use the following procedure.

Approach the tent and press a small area of fabric over your mouth. When breathing out if you feel the air flow in the palm of your hand, the fabric is considered breathable.

Therefore, choose carefully!

Anti-shock fabric and design

If you are facing windy weather conditions, both in North and South, on an highland, on an ocean's coast or in a "home grown" lake, it is unavoidable to feel uncomfortable, if you are not suitably equipped. For a surfer, wind means guaranteed fun; for anyone who stays overnight in a tent, which is two meters high from the ground, with light, flapping and noisy fabrics, sleeping quietly in windy evenings is a privilege reserved to others.
With Overzone a quiet rest is guaranteed! Its strong and firm fabric does not swell out: even on the lee, "sail effect" is avoided. The correct design (Anti-shock) of windows and roof (single piece, compact and different from others: not artificial) prevents dangerous whirlwind from creating (they often cause unpleasant surprises tearing, or fabric damages), assuring stability and quietness.
