I frequently use a suspender inside my shirt or on top of an undershirt, before I put on a thicker polo or poloshirt. This system beats any good belt. This one is a bad buy for me for that purpose or with normal wear (outside a longsleeves). The suspender is made of very flimsy material, the suspender is re-adjusting by itself as a result. The teeth of the mechanism can't retain its bite lock because the material is too thin. The clip also re-attaches from thin wool pants. This is not a useable product. Fail!
