I bought a pair of Green Park denim breeches and a pair of Parbold breeches.
Obviously not washed them yet, but they seem good quality.
In the past I have found DH jods to be on the small side and always tight on the knee. These seem to have plenty of 'give' in them. I reckon they are true to size. I bought size 24 and they fit fine the next size up would certainly be too big. I do think you need to be honest with yourself though and measure your waist not just buy what you think you should be!
