light weight shell
My pull over does not look like the one in the image above. It works well while exercising to vent moisture and perspiration. It blocks the wind well. It is easily packed into a small space in my Camelbak.

Great lightweight windbreaker
If you can't get enough Arc'teryx, hurry and grab this piece before it's gone. The gamma lt pullover is LIGHTWEIGHT - which is great for fair weather active efforts - i.e. morning jogs. It would not be a good piece if you are looking for insulation. The Gamma LT looks good enough to easily get away with it in the office or out to dinner. I would describe the fit as athletic - consistent with most Arc'teryx stuff. This was my first experience with Altrec and they were great.

Good Lightweight Shelll
This shell blocks most wind yet breathes and repels a reasonable amount of rain. It takes almost no room in your pack and so is a good item to carry if the weather looks changeable. I use it more for travel than trail because it fits so easily in a small pack or bag. On a recent trip to Paris in September this was sufficient, with a Delta LT zip top, on blustery days and in the evenings. It's stylish enough (and breathes enough) to leave on when you duck into a restaurant. In general, it will add/subtract about 10 degrees of temperature adjustment when you put it on or take it off. Buy one size up if you want to wear layers beneath it.

Great.......
This is the second gamma LT pullover i purchased and am just as pleased. I use them for work as well with a white collared shirt it looks sharp.............. Might pull the trigger for the Red one too..........

Great awesome pull over!
This is great in all kinds of weather conditions. it is fashionable and get many compliments on this as well. You need one of these when you are running in the Midwest in late fall and early spring. I am thinking about getting another one in a different color too.
