Reliable and True to Their Reputation
Bought the Mountain Hardwear Windstopper Vest prior to going to Alaska. I'm 6'1", 205 # and found the fit to be pretty true for my frame. Wore it while cruising an eagle preserve as an inner layer with a shell on the outside. Kept me warm and toasty. Hiked Mt. Roberts in Juneau with the same MH shell and MH Windstopper Vest and it performed great cutting the wind while keeping me comfortable.

Indispensable item
I have had this vest for several years and loved it. I have worn it backpacking in Colorado, biking in TN, flyfishing in Arkansas, adventure racing, as well as to kids football games and even church on Sunday's! It layers well, really stops the wind, looks good and cleans well. Lightweight and takes up little space in a backpack. Very tough piece of clothing, only replacing it because my wife lost it at football game (thanks dear, for an excuse to get a new one)! I consider it an indispensable part of an active, outdoor clothing list.

Great Vest
The other reviews give it 5 stars for all the same reasons. MH quality and attention to detail. The vest is bomber construction, thin (but the material is dense/solid) so it works well under a shell. Warm enough to worn alone. Trim athletic cut fits great, not bulky or boxy as some vests. It is not too long which is nice for layering under a shell and getting to a harness. However, it is not super light at 13oz, nor real compressable, but the trade off is a durable vest. A large fits perfect at 6'1", 180lb.

Good looking vest
Vest looks good enough to wear in the office, not just for outdoors or casual. Goes really well with a white LS shirt. Only exception is maybe the collar is a bit high but in the end, it's not so bad. All seams and zippers are classy and the logo is perfect. Even if you are not a "vest" person, this one can be your first and only vest.

Great Vest
Recently purchased this vest and wore it hunting in the snow and wind last week. Very comfortable with great ease of movement. Good protection from the wind. Fits true to size.
