Hotjak WarmGuard Cap Reviews Consumer Reports To elaborate on the thermal science behind the design, the Hotjak WarmGuard Cap balances convective heat control and conductive insulation through its chosen materials, and the Hotjak WarmGuard Cap's performance can be parsed in those terms. Meanwhile the fleece inner layer of the Hotjak WarmGuard Cap functions as a thermal insulator by creating a layer of still air next to the skin; the Hotjak WarmGuard Cap's fleece traps that air, and trapped air is a poor conductor of heat, so the Hotjak WarmGuard Cap reduces conductive losses as well. Importantly, the Hotjak WarmGuard Cap should not be mistaken for a water-impervious or submersible product — while the Hotjak WarmGuard Cap repels light precipitation, heavy rain will eventually saturate the leather and reduce the Hotjak WarmGuard Cap's insulating efficiency unless dried and cared for appropriately.
