Recommend not wearing a G-1 in S TX during the summertime. Other studs will also probably not be wearing one.
As for the Massif, I like it, got issued via squadron MCO buy (it's not something that will be issued by CNATRA or FRS). There is another similar one that is much cheaper, which I bought off amazon....it just doesn't have chest patch velcro like the Massif, thus making occasional CPO's cringe. Can't remember the name. Both are infinitely better than whatever ridiculous garbage jacket the supply system tried to replace my nomex's with. That thing is an abortion. It looks and feels like wearing a green denim jacket. I'm sure the cost per unit for the manufacturer is double digits, and they charge the government triple.
