The suspensors works really well and very comfortable to wear. Very easy and quick to fix too. No problem of adjusting my pants every time I stop. Just suit and ride.
I bought the next size of riding pants just incase my waist line increases later on. However the result was that the pant tended to always slide down a couple of inches from the waistline due to the weight of the material and the armour - requiring constant adjustment. The suspenders solved that problem
I wear the suspenders over my vest/banian and then put a tee shirt over it to cover it. This way you can wear it discreetly at all times.
