I have the urge enduro matic. It comes with a front and back pad, both in thick and thin, giving 4 fit combinations for each helmet size. Mine fits great, and is rock steady, even with a light on the front.
I had a big off in the Alps last year ( on YouTube, search “Dans crash Stu Mac – I crash at 1:05) and I was very glad for the protection afforded to the back of my head – there is a dent in the lower back portion that would be unprotected on normal MTB lids.
I’m also a sweaty git, and the gangsta pad does a great job of sucking it all up.
