I didn't find this on the search so i must assume it has never been covered.
How often do you wash your deer stalking clothing?
My advice is don't!
Hide it from your partner (they seem to search it out by smell and wash it) i suggest in a shed or garage.
On more than one occasion,as happened last week, i was downwind of a group of red stags, i didn't know they were in the next field, but could smell them!
After getting the beast back to the larder my clothing had 'stag' odour, this mixed up with roe and fallow can have an advantage,honestly!
Its when the wind is eddying around you you will be grateful your gear is rarely discovered by 'her indoors' (sorry ladystalker).
Hope this tip helps and does not lead to the divorce court!
