Getting a good night's sleep is extremely important, especially when you are supposed to be out in nature enjoying yourself. Becoming wet or damp in the night is going to increase your chances of getting cold quite considerably.
The British Army Goretex Bivi Bag is designed to stop you from becoming either wet or damp. When your sleeping bag or clothing becomes wet it loses virtually all of its thermal retention properties, so the prevention of this should be high on the list of any serious outdoors person.
Essentially the British Army Goretex Bivi Bag is like a large sleeping bag cover that can be placed over your sleeping bag in order to make it fully waterproof.
It is made of a very interesting fabric known as Goretex. The way that Goretex works is that large particles such as water cannot move through the fabric, however, smaller particles such as water vapour can pass through the fabric. For this reason the British Army Goretex Bivi Bag is also breathable, making internal condensation a thing of the past.
All seams within the British Army Goretex Bivi Bag are taped for added protection and strength as you would expect from a genuine military item such as this.
The British Army Goretex Bivi Bag is 260cm long and is the classic 'mummy' shape in nature making it 62 cm at the bottom of the bag and 92cm at its widest point. This allows extra room to place in thicker four season sleeping bags and even a roll mat.
Once inside the British Army Goretex Bivi Bag a drawstring at the neck can be pulled to completely close off the opening into the bag and keep any rain at bay. Remember it doesn't matter if you close it up completely as your breath can escape through the fabric and won't condense.
The extra layer of fabric around you creates yet another 'air trap' for warm air and another barrier to the wind, helping to increase your warmness.
The British Army Goretex Bivi Bag is technically a shelter in itself, so you can even remove the need for a tarpaulin for both ground dwelling and hammock camping, giving you a feeling of oneness with nature and a full field of vision around your camp.
Perfect for those wanting to camp with minimal equipment and for people that want to sleep sound without the possibility of waking up soggy or wet.
