Israeli company Polaris Solutions Ltd produces multispectral, 3D camouflage systems under their Rajuga line. They offer a wide range of different systems, ranging from observation port or sensor covers to full on OPs as seen below (front then rear).
Different visual camoufiage patterns can be printed on either side of the Thermal Visual Concealment panel and the material also provides protection in the IR spectrum. Additionally, the TVC material offers sun, rain and wind protection and is bery lightweight at .7kg per sq m. It folds or rolls flat for transport and can be individually configured to mimic local terrain, offering a very effective 3D effect which sensors or observors can be concealed under.
The desert patterned system seen above is the Sniper kit. It sits atop a rucksack cover which is also part of the kit.
Polaris Solutions products are available through Rampart.
