The Survitec OTS 600 Dry Suit minimizes the effect of cold shock and provides essential thermal protection to extend survival time significantly.  The garment is both lightweight and breathable, allowing a strenuous activity to be undertaken without the wearer suffering the effects of heat stress. Initially developed for Offshore and Rope Access operations the OTS is also available in a military variant, approved for use on both fixed- and rotary-wing aircraft.

Fundamental to the development of the OTS 600 has been the independent ergonomic and cold water trials to which it has been subjected. The garment has proven to be comfortable, practical and compatible with other flight clothing having been tested rigorously by end-users on both helicopter and fixed-wing platforms.
