My personal choices are:

I love Arcteryx backpacks. One that I use Arcteryx Arro series. It has a room for bladder and pack is also water resistant for rainy days. The zippers on the pack is self-sealing so rain or splash can't get thru it. And since back of the pack is very well padded it really feels comfortable.

Somebody did mention Zipka headlight and I would second that. It may not be a search light but for camp, hiking, climbing use it is really great. As a backup I also have Inova X5 flashlight. Great product, small, waterproof and durable. The only problem tehre is with Inova flashlight is that it uses lithium batteries which are little expensive but the light is definiately worth it.

As far as the coat goes. I usually dress in layers so I don't really have what you would call an all around coat. I do have a nice Gore Tex shell and plenty of fleece underneat to keep me warm anyday. But if I had no option as far as layering goes I would go for M65 field jacket. I think those are the best.

And now the pants... I went out to couple of Army and Navy stores to pick up some surplus BDU pants. Not all of them are the same as I assumed at first. There are the cheap ones that would be ruined after few washes and there are the ones that can be used over and over again. I think the ones that have original military tag are good not the immitations. Another place that I buy my cargo pants from is Abercrombie. They are about $50 a pair but they are really comfortable and long lasting.
