I really like my Sno-Skinz cover and it seems very well made. I have a year of use on it and it is just like new. I have never seen or used a Skinz cover. I think my Sno-Skinz is better made than the Polaris OEM covers I had in the past. I did some searching on here for Sno-Skinz covers last year and all the reviews were positive. I have also read lots of positive reviews for the Skinz covers. Hard to beat the warranty of the Sno-Skinz covers though: "Sno-Skinz builds its covers to last, so we 100% guarantee satisfaction on delivery and guarantee against structural failure in materials and workmanship for as long as you own your snowmobile."
