Stearns' Cold Water Immersion Suits have no separate insulating liner, and are generously cut to make donning straightforward and struggle-free in chaotic emergency situations.
They incorporate a built-in helicopter lifting harness with stainless steel hardware, and a buddy line with snap hook. The built-in buddy line prevents victims from drifting apart, greatly increasing chances of survival and recovery.

Complies with SOLAS Chapter lll, IMO RES.MSC.207.(81) and MED Approved (European Marine Equipment Directive; Ship's Wheel).
This suit does not have the inflatable pillow head support required for USCG approval; see the Type S suit for this feature.
