Try arborist supply stores! Pfanner makes a decent pair. Chainsaw pants are heavy and need the extra help. Theis store is Canadian, but you might have more local options: https://www.arboristsupply.ca/product/classic-suspenders-pfanner/444?cp=true&sa=false&sbp=false&q=false&category_id=169 Something to note here is that these do not have clasps. Clasps suck. If you are wearing pants that do not come with buttons to attach suspenders onto, it is very easy just to sew some on.
