Bivy tent shelters are one of the most common trends instead of the regular tent when camping. Defined, the tent is also known as the bivouac sack that is a small lightweight waterproof shelter that is alternatively used during camping outdoors. The design of the bivy tent is made into a thin waterproof shell that is made to slip over a sleeping bag.
One disadvantage of the design is that it produces humid effects wherein the inner of the sleeping bag becomes moist leaving the user or the occupant inside the bag wet or moist when sleeping. Bivy tent shelters in recent years were developed to solve this problem by using waterproof and breathable fabrics.
In recent years, the bivouac shelter or bivy tent has evolved from a simple top cover to the sleeping bag. Nowadays, it has developed to the single person bivy tent. The tent often requires the use of hoops on top of the head and feet that keeps it stable and firm to hold the fabric from the person inside the tent. This is to prevent the condensation that happens from getting the bedding of the bivy tent wet.
Most campers and mountaineering adventurers now prefer the use of the tent as it gives the more comfort than ordinary tent and sleeping bags. Traditionally, the bivy sack is used during long and dangerous hiking or hill walking treks and expeditions. In the some countries in Europe, the bivy tent are popular amongst coarse fishermen and large carp fisherman as they usually spend long nights out at the sea.
When buying the bivy tent, consider the size and built as you may need to palce a winter mattress in it for some time. It should also have room for headspace and for some camping gear. Features of the tent should also include factory sealed seams and mosquito nettings.
