Seat Covers??

Mazda 3
Hey all! I have a 2015 Mazda 3 sedan with cloth interior and I'm having issues finding front seat covers that fit. I've bought a few sets from Canadian Tire and they are not big enough to cover the large front seats. I wanted to purchase the Kurgo ones because they are fantastic but they are not side airbag compatible. Has anyone purchased seat covers for their mazda? I'm looking for something waterproof and under $100. Thanks!
