Rated 5 out of 5 by from My Vest I'm very happy with my purchase. The vest is stylish and keeps me warm on cool days. It has two pockets one in the front perfect for my 6 plus and one inside large enough for my oversize wallet. Love it.

Rated 4 out of 5 by from Good Vest for the Price, Runs Really Big Overall this is a solid vest.  Ordered the "Green Mustard" in medium as I have a medium softshell from Marmot.  First thing I notice that the color is awful.  On the the website it appears to be more of a yellow, however the "Green Mustard" description is without a doubt more appropriate.  Although my closet looks like a highlighter, this color was even a bit much for me.  The medium was huge on me (5'8" -140 lbs) so I exchanged it for a small.  Definitely should have followed the size guideline on the Marmot website.  Note that the small is still quite roomy on me.  If you are looking for a trim fit vest for mountain going I would not recommend this.  Note that it still does pack down to a reasonable size for throwing in a daypack. As I got a great deal on this vest on sale and winter sales were over, I decided to keep it.   While it is not super lightweight like other down products I have seen in the market, I have found a useful spot for this in my wardobe.  The outside shell of this appears to be very durable.  So much so that I feel comfortable wearing it to gather wood, maintaining the campfire, and walking though the woods.  The drawstrings at the bottom of the coat help with the fit a bit, although I can still fit mutliple layers underneath.  The fleece lined pockets are so soft that I can't keep my hands out of them.   Overall if you have a wider waist and frame this is a great vest, Someone with a trim build will likely want to shop around for something that fits a bit more snug.

Rated 4 out of 5 by from Quality is solid but the features are lacking. Pros: strong materials...well constructed...fits as advertised...doesn't lose the filling. Cons: not packable...outside hand pockets not zippered and not very deep so it's easy for your keys or phone to fall out.

Rated 5 out of 5 by from Solid vest! Happy with the Ajax Vest. This is my second Marmot vest - the first was a 800 weight, which has served me well. This one at 600 is perfect as a base layer and great for San Francisco every day wearing as well!

Rated 5 out of 5 by from I love my Marmot vest It's just what I wanted, and the service was excellent. The shipping department even got the order out for me the next day, even though I ordered it past the cut off time for next day delivery.

Rated 4 out of 5 by from Very light weight this is what i was looking for - light weight with some good warmth - inside and breast pocket have zippers - side hand pockets do not - got it on winter clearance made it even a better buy
