You may want to invest in a pair of Bosch Icon wiper blades. The Bosch Icon uses cutting edge technology to provide benefits like uniform pressure along the blade length, and a smooth and quiet operation with 20% longer life than other premium blades.
However, the biggest benefit for those driving in the snow is the protection against snow and ice buildup provided by its weather shield connector system. Jeep Commander owners that have upgraded to the Icons are very satisfied with them.
While not cheap (MSRP $33.38) the Bosch Icon is well worth the price of admission (even though chances are you may be able to get them for less than MSRP at your favorite auto parts store). The part number for the Jeep Commander compatible Bosch Icon wiper blades is 418A, and they are available only for the front windshield.
