Before I ever joined the Air Force I had one of these. I bought it used at a surplus store and wore it throughout high school. I got two while I was in the military and my son now wears one of those. I've outgrown them, but I just bought another.
The jacket has a removable liner that has full length sleeves. The shell is a tight weave of cotton/polyester. It blocks the wind fantastically. It's moderately water resistant and with a coat of Scotchguard can handle light rain long enough to get out of it.
With the liner removed is is a great medium weight jacket or wind breaker.
The collar is not wide. When folded down it's easily out of the way and stays in place. When up, it has a little velcro tab to hold it closed which keeps the wind off your neck very well. Inside the collar, under a zipper, is a light hood. This stays out of the way in it's storage pocket, but is easily accessed if needed for temporary wind/water resistance.
It has 4 pockets which are large enough to hold necessities. The hand pockets have flaps which can be tucked into the pocket. This makes them nice hand warmer pockets or they'll function nicely as "dump" pouches. The breast pockets are large enough to hold a full sized glasses case.
The sleeves have a tab or flap that is triangular. It folds into the sleeves and is held in place with a piece of velcro. When unfolded it adds some length to the sleeve that doesn't get in the way of your hands. I've never extended them, but I guess they could be nice in windy weather.
The jacket also has two cinch cords. One is at the waist level and one at the hem. I like to cinch the one at the waist a little. This keeps the wind from getting up inside the jacket.
In case you can't tell, I like this jacket. Over the years I've owned probably a hundred jackets or coats. I have yet to find one that is more functional than this one. If you've never tried one, give it a shot. There are plenty of colors available. I just bought one in black.
