|To assist with keeping cool Marc has been constructed pockets behind the chest to hold Ice bricks
In this photo I have one brick inserted in the left pocket and the other just resting outside.
I usually carry two to three sets with me.
|There are two fans in Marc's head.
One pictured here which is above the ear and sucks the hot air out of the head piece.
It is a 5cm VGA cooler fan rated at 5v.
|The second fan is behind the muzzle. It is a 2.5cm laptop cooling fan - also rated at 5v.
It will keep a gentle breeze on my face at all times.
Psychologically this is great as I never get the closed in feeling and there is always fresh air.
This is shot looking out of muzzle from the inside.
|Another view of the muzzle fan but looking through the jaw. It is the thin white strip.
From the outside it is invisible and both fans are extremely quiet.
A two way switch located at the side of the headpiece under the fur will turn on either one (the head fan) or both the head and muzzle fans on.
This is easily access though the fur. and to outsiders I am merely scratching at me neck for a second.
|All electric's (including the eyes) are powered by 4 x AA size Nickel Hydride batteries.
These are rated at about 1800mah|
This gives me about 5 hours continuous running and I always carry a spare set.
Here is a picture of the batteries in-situ in the foam cavity at the back of the mask.
You can also see the quick connect plug and socket.
|Another view of the battery pack partially pulled out of its cavity.|
These are just held in there by the tightness of the foam
And I have never had them move whilst I was running around.
