well,i got one of the muflon jackets anyway,so heres a quick review of my own...first time on today,out beating,and the rain was relentless,so was keen to see how it performed.I stayed dry all through the day while others around me were soaked to the skin with the clothing they were wearing,mainly seeland.I think the only thing I would say against the muflon jacket,is that it would do better to have some under arm ventilation,as some other jackets have.I did sweat a lot,but on standing waiting to beat the next drives,i soon dried of sweat,I did have a couple of good extra layers underneath,so maybe just a thin fleece type top and tea shirt may have been enough,so at the end of the day I would recommend this jacket to keep you very warm and very dry even in the wettest of weather(such as today)...
