I have the AIR7 that you posted in the top link also. Of the vest I have tried in my life, I like it the best. I will say for people who wear larger sizes, be very careful with the size chart they have. I was on the lower end of the XXL (which is not uncommon with Asian measurements), but I ordered the XL because I am trying to keep working out and losing weight. From day one it was too big. I have it on the smallest possible size where velcro is rubbing on my skin if I don't wear a shirt under it.
So basically if you order the AIR7, be warned they do run big, especially the larger sizes. If I had of known I would have ordered a L even though the site said I was an XXL.
