The Wolf Headdress introduced with the Frostline update is nice, but the fact that it weighs five (5) whole kilos makes it rather undesirable, especially when factoring in how easy it is to acquire any other high/best insulation hats.
I suggest reducing its weight to be more in line with other items providing similar stats to not have it be reduced to a gimmick (anyone able to deal with a Wolf pack will have an objectively better hat already, objectively meaning raw stats such as insulation and water absorbency, not accounting for personal tastes).
