I paid £20 for my jodhpurs. And £22 for the mucker boots I ride in - I went for comfort over anything else. Add on £20 for a pair of half-chaps and that's me sorted for learning to ride!
I can understand boots costing more - they're difficult to fit and comfort is important, hence why I got the lovely fleece-lined boots. But how on earth can a pair of jodhpurs, no matter how fancy, cost more than £70 or so? Has every loop of the weave been hand-crafted to glue you into the saddle or something?!
