On this past week's episode, I discussed the "Big Air" ventilation system on the Dakota II jacket review. Some years and versions of the Joe Rocket Ballistic (and I believe the later-years Meteor?) also included that. Here's a link to a recent version of the Ballistic jacket that includes this same air management system. It's a neat design and I like it quite a bit. There's no ambiguity on whether the air will it you just right and flow into the vents. The jacket front *IS* the vent, so it's kind of a no-brainer. Anyway, just thought I'd take a minute and toss out that note.
