Mine has done about 13 years, the zip has broken and the cuffs are wearing through...
I have found this one from NorthFace but it didn't seem quite right.
I want it to be long - I've a long body and most standard size stuff is just a little bit too short.
I need to be able to wear it skiing, snowshoe walking and to the office.
Easily washable. Long lasting. Doesn't necessarily need to be rainproof although I would like something windproof.
