Normally DPM combats (because they didn't have any olive in my size at the surplus store I went to), which have taken a battering and are still going strong. Walking socks and walking boots
Dependent on how cold it is as to what I have on top, normally any of my normal (non-violent coloured) tshirts, Green norgie or fleece type jumper. If cold I have a thermal ls top on, if not it's in my bag (Im a pretty cold person!)
Then a brown cotton windproofish jacket, spare socks, wooly hat and waterproofs in my bag.
If it's really chuffing cold or wet, I have thermal trousers and sealskins gloves with me too.
I tend to go for surplus for it's hardwearing qualities, but avoid DPM where possible. I don't tend to buy expensive bushcraft-specific clothing, because there are very few items I can't find a cheaper, just as effective alternative to.
I stick to my greens and browns, blend in, stay warm and dry quickly, without looking like a military obsessive, or paying out shedloads. Works for me
