What helps protect against hypothermia in aircrew gloves?

In aircrew gloves, insulation and water resistance are essential features that help protect against hypothermia. Insulation works by trapping heat close to the body, preventing it from escaping and helping to maintain a stable temperature even in cold environments. This is crucial for aircrew members who may be exposed to low temperatures at high altitudes or in adverse weather conditions.

Water resistance also plays a vital role, as moisture can significantly increase the risk of hypothermia. Wet skin loses heat more rapidly than dry skin, so having gloves that repel water helps keep the hands dry, contributing to overall body warmth. Together, these factors ensure that aircrew members can handle cold conditions without the debilitating effects of hypothermia.
