Ive been relatively happy with the cold snap on the SM. 2 downsides I have found are…
1. If you are drilling lots of holes in very cold temps the blade and auger flighting likes to ice up and the cover does not fit well. Does not happen too often though.
2. the band that holds the cover on is just a slice of tire inner tube. Again, in colder temps it will lose its elasticity and the cover fits pretty loose.
That said, I think they are a better cover than the stock cap. And would buy another if I lost mine.
