OTS Mid-layer Immersion Suit

Designed for over the side work on platforms, vessels and offshore wind turbines

The OTS is a new approach to immersion protection and takes the form of a water-proof undergarment, worn close to the skin and under normal work wear. Designed for constant wear, the OTS is both practical and comfortable when worn over long periods. The fabric comprises an internal fleece layer providing thermal properties. The PTFE membrane provides waterproof, breathable protection, with a protective knit to the front. In addition, new zip, wrist, and neck seals have been incorporated, all of which maximise comfort without compromising water integrity.
