Although I haven't used these specifically the Ultras come with the adjustable wings and those makes a major difference; I'd assume these would work as well except they don't open for extra ventilation when you need it. It can get pretty stuffy on really warm days when they are closed.
We will sell Hawg Wings to HD members for $21/ pair. Leave a note a when checking out, and we will issue a refund. This offer good until the end of this month. Thank you
