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've not personally skinned a wolf to wear its face on my hat IRL, but that thing should weigh two kilos tops, if even that.
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 not accounting for personal tastes).
