If it is for HFT only and camouflage isn't a problem then I would recommend going to your local go outdoors and buying a pair of Salamon X ultra Mid 2 walking boots they are light, durable, water proof and breathable.
Then a set of good walking trousers I have a pair of Rab but Berghaus and Montane make could quality ones also.
Multi layer tops including base layer such as a Helly Hanson, long sleeve shirt and soft shell jacket so you can adjust accordingly depending on the weather and if you wish some sort of baseball cap.
Go outdoors tend to be very good value and always have discounts.
