Finland Jama Bushcraft Blanket Shirt

[harrypalmer]

"The close woven wool outer is perfect for dry cold and powder snow" which we don't get in the UK.

If you want a 'natural' material outer then look at Ventile, its expensive but windproof and will keep some rain out, beware though, when it does get wet it will leak, go as stiff as cardboard and is a bitch to dry.
