What is the biva?

BIVS, also called bivac sack or biva, is a light protective device most commonly used in camping outdoors. It should be large enough to fit on a sleeping bag of a person and offer further protection against weather. Patrol is supplied in a number of materials and fabrics, but its waterproof abilities are a big factor when deciding what type to choose. Campers can think of it as a small tent for one person and his sleeping bag. The bits can be made of very lightweight material and can weigh less than the tent mat. The material should be breathable to remove condensation, but also waterproof to prevent wet sleeping bag. It should also have enough space to store some equipment. Ideally, the bag should be prevented from blowing under high wind conditions. The bonnet can also be made of mosquito -resistant material. Alternatively, mosquito -resistant mesh can descend through the front of the bonnet and be connected by pageAnách with closure of hook and loop or zipper.

BIVS is an excellent choice to add heat when sleeping outside, and you can find it in the most experienced tourists. The more sophisticated product is made of materials such as Silicon and Gore-Tex®. It cannot guarantee protection in torrential downpours, but it is evidence of shower and rain. This device has the biggest advantage when a hiding place was found, such as a cave that has strong condensation.
