Keep in mind that the AD1 are IIRC not made in the USA... I like my Darien pants for three season and my airglides for summer. (I've only used the airglide liners under the Darien on rides that were REALLY cold, like below freezing. If you think the airglides were heavy, you will think just about everything on the market is heavy, since it's hard to get protecting and windblocking with out a little bit of mass. Good luck on your search.
