Marmot Men's Original Driclime Windshirt

A very good windbreaker
I'm very very happy with this. It's basically a long underwear shirt with a nylon shell over it. It's more water resistant than I expected. I spent a day in light rain and never needed to bust out my rain jacket because this did the job. It's very warm for it's weight.

Light weight, tough protection
A late spring, summer, early fall type of jacket. I'm 5'8, 150lbs and the medium fits with plenty of extra room for layers so I can even use it in cold weather. Definitely not an athletic cut so I'm considering purchasing a small for trail running. In some products the mesh vent performance is barely noticeable but in this jacket is is very functional. Check out Marmot Catalyst jacket if your looking for something with more stretch and pockets.

Great on the trail and around town
The Marmot: Men's Original Driclime Windshirt is a winner, no doubt. The shirt is so breathable, moves smoothly, and is just wind resistant enough to keep out the bite. I wear this for long and short runs, also to work, and out and around with my wife and kids. Love the windshirt, will buy more.
