I have had my Scotts e-vest for just over a year and really like it. The design is good, and you can carry a lot of gear without having to have a day pack. I like how I can go from a fleece vest to a jacket to a full winter coat just by adding sleeves or the outer jacket. My only complaint is the little cards they put in every pocket, letting you know what it’s for. I have had mine a year and just found another card, will it ever end? The outer coat is a bit bulky, so it’s not really good for packing up in a bag. For a good review check out
