Very comfortable. Adjustments for a wide range of sizes. I'm 4'11" and always have trouble fitting a vest to my small frame. The multiple pockets are a nice addition. The size zip, that fit my iPhone 5 does NOT fit my iPhone6, so that's a bummer. I like to have it within reach to change music or take a nice picture. Other than that, I like all the pockets and extra zip in the back to hold a change of shirt, or a removed layer if necessary. I would definitely recommend this vest.
