I want to get a buffalo Jacket........
I have done a lot of hill walking and my last jacket, a mountain equipment karakoram (sp?) cost me £260 and is a top of the range jobbie, but during a walk up a mountain in Scotland in the rain, I got just as wet as everyone else. I sweat a lot, esp climbing a mountain and although the jacket was shedding the water well and not wetting out, it could not transfer my sweat quickly enough and I got soaked. You will find that, whatever you get, it will not be suitable for all situations. Have a good think on what you want the jacket for before spending your money and try to get something that will suit most of your needs. If it is mainly rambling then goretex xcr is hard to beat, but not good in the cold, by a fire or walking through brambles or thorns, or over sweating.
Ventile is tough, but once wet, it takes a long time to dry out and is heavy. Waxed jackets are tough too, but don't breathe, so best for sitting on a tractor or a horse.
Paramo is supposed to be good, but needs re proofing regulary and you tend to get hot in them.
Buffalo has a big fan club, as seen above and probably below, if you do get wet, you will still stay warm, but its not good round a fire, near the brambles and thorns and not for summer use. Most people wear them next to the skin.
I am probably going to get shouted down now as jackets are a personal thing and some people may of experienced different things to me and some of what I have said, I have not experienced myself, just read it in trail magazine............
