The Camera Bivvy is a low cost & extremely light pop-up tent that provides a convenient, protected environment to change a lens or clean the camera sensor. Weighing less than 120g (4oz) & only 16cm (6in) in diameter, Camera Bivvy is small & light, yet it instantly pops up to form a 30cm (12in) protective cube. Simple armholes, with elastic seals provide easy access as does a zip closure. A clear front window lets the user see clearly into the tent.
