Cryosuit

The Cryo suits are of three layers but the inner layer overall omits the insulating layer above the waist (covered by the overlapping jacket) for comfort and to reduce bulk.

The outer layer of Royal Blue, woven polyamide has a waterproof coating to resist condensed water on cold surfaces yet it remains permeable to water vapour so that there is no clammy condensation inside.

The middle layer is of special polyolefin/polyester micro-fibre, which is almost twice as effective in thermal insulation as a similar thickness of 'down'. This minimizes heat transfer without being so thick as to be cumbersome. The inner layer is of cotton for comfortable wear.

The jacket has a hanging loop inside the collar, so that they may be hung in a convenient place away from pools of condensation when not in use.
