I love Buffalo kit. I've got the unlined Windshirt and the Pertex 6 Special 6. Both great, very tough. My mate has had his Mountain Shirt for ten years and it's starting to look a bit battered after many a winter on gritstone, but it's still going strong held together with packing tape.
For the amount of use you'll get out of it it'll seem like a mega bargain. Got mine for 80 quid when I was 15, I have certainly had more than 80 quids worth of warm and happy out of it.
In reply to paul walters:
can not go too far wrong - had mine from '92-2004 before it finally
died and it got a lot of hammer. Have tried Gore-tex and now paramo
but still think excellent kit for UK use.
(and very tempted to get another)
I'm afraid I didn't like mine and passed it on to my mum. The velcro neck thing works okay on a Pertex Pile shirt, but I found it slow drying and just generally uncomfortable on a windproof.
I replaced it with a hooded Ventile windproof from Hilltrek, which I love, but if you prefer Pertex another option would be a Rab Alpine Pull on...
