Acrylic Hat with Thinsulate Thermal Lining, Grey, LahtiPro

Grey hat from LahtiPro with an outer layer of 100% acrylic and an inner thermal lining of Thinsulate. The hat is designed to retain heat.

The lining is a double-layer Thinsulate from 3M with good insulating properties. The microfibres of the material create microscopic air gaps, so the insulation is not compressed during use, and heat retention is twice as effective as with insulating materials from other manufacturers.
