A flashlight that I always carry around with me is the petzl zipka. It may not suit you but I find it really useful. You can use it as a head torch or on your wrist or you can carry it normally. It uses 3 LEDs and 3AAA batteries.

I once had a pair of khaki combat trouser that I got from a surplus stall at a show. They had reinforced knees and inside leg/seat, as well as being to layers thick anyway. They were great. They lasted for ages. Unfortunatly that was about 3 years ago and I have never seen a pair since. I have seen the stall owner more recently and asked him about them but he too hasn't seen any since and doesnt know who made them.
