Isolation suit

Anthropological isolation suits are highly technological type of clothing used by the Federation on pre-warp cultural observation or 'duck blind' missions. They are equipped with a basic Cloaking device which makes the user invisible to natives so not to contaminate there culture but are quite visible with properly configured sensor equipment which the base of operations for the mission will generally utilise to keep tabs on there personal in the field.

When visible the suits are a red colour and look somewhat like EV suits. This is no coincidence as the suits are sealed well enough to block out the noise of operatives in communications with the mission base from close by natives.

In 2376 the Trill Hiziki Gard used an isolation suit to evade capture after he assassinated the Bajoran First Minister, Shakaar Edon on Deep Space Nine. The ploy was successful for some time but he was eventually tracked down by lieutenant Ro Laren and Taran'atar hiding in a small crawlspace above Ops. (DS9 Novel: Mission Gamma, Book 4: Lesser Evil).
