Now, you can also kick it old school with winter wiper blades but keep in mind though, that those usually are standard conventional blades with rubber boots over them so snow and ice can't clog them.
No matter what, make sure you don't just measure size and grab them off the hook. Be sure - especially with volvos - to look them up in an application guide or computer box at the store. Now-a-days you can also look them up online. Try searching "lookup wiper size" or something like that and you should be good-to-go.
