Nice Stylish Midweight Jacket
Color: Dark Grey, Size: Medium, Color: Dark Grey, Size: Medium
I ordered this jacket because I wanted something with a little my style to wear out to dressy casual occasions. This jacket fits the bill. It looks nice in that it's got a casual laid back feel but at the same time you could wear over a collared shirt and it would look good.
I am 5'10" and about 165 lbs. I normally wear somewhere between a medium and large depending on the brand. I ordered a medium and it fit well. The arms and body were both the right length, not too short like some other jackets.
The reason I took 1 star off was because this is advertised as a winter puffer jacket and I wouldn't really call it that. It is a mid weight jacket that can get you by in southern winters but anything really cold I wouldn't wear this. Plus it's not a "puffer" jacket. It just has a minimal quilted feel to it but most of it is just a polyester glossy sweatshirt feel.

Maelreg Does It Again
Color: Dark Grey, Size: Medium
I just wrote a review for another Maelreg product. They're all good! lol 21st century fabrics are here to save us! ;) This one is also really well made. I love the fit and feel. It's perfect for those mild fall/spring days where an extra layer of windproof protection is just really handy. The arms aren't insulated, so it's great for active outdoor ventures. I use mine for jogging over a poly/blend wicking tee. It lives at the office where I sometimes need a stylish overcoat in the A/C freezing office. I bought a size M for my 5'10" 175 lb. frame and it fits perfectly. Just long enough to sit at the top of my glutes. The front of the jacket has a nice contrast/sheen that you don't see everywhere, it's a nice style addition. The poly blend fabric adds a nice degree of flex to the fit, it's comfortable under a heavy overcoat or over a light thermal layer. Super easy to launder on cold/low, and really low temp iron to rid it of those packaging wrinkles, and its easy care forever. Great product at a really nice price point, all things considered.

Beatiful, light, sytlish jacket and you will receive tons of compliments on
This jacket is simply beautiful and well made. I took this out on a boat ride out in the bay and it was perfect. The materials are super soft with the spandex in arms, shoulders and back. The front has a very sylish super soft light weight fleece and the neck has three different colors in the inside which make the jacket pop. I recieved a lot of complements on the glacier grey and the large fit me perfectly at 6ft 190lbs. This is extreamly well designed and relaxed but stylish and can be worn for different occasions. This is a jacket that will make you stand out and get compliments. It is light weight so this is not a winter jacket but is perfect for 55-70 Degree weather with Tshirt underneith. The colorway on this glacery gray is well thought out and looks blue to me. Great overall and don't feel its too long in arms or overall length as another user posted.
Updated: It did not shrink in cold/warm wash. I wanted to add that after washing the jacket was very wrinkled and care instructions are low heat. The jacket looked awful so I had to use a steamer to get out the wrinkles. If you do not have a steamer you may want it dry cleaned.

Machine washable, and machine dryable
I have no idea what these jackets have to do with playing golf, but they are very comfortable and an excellent value.
Something that is very important to me, is that this jacket is machine washable. The product information does not provide specific care instructions regarding drying. I guess I could always put the jacket on a coat hanger and hang it in the bathroom until it dries. One star demerit for not addressing the drying aspect.
I have tried this jacket on and it fits perfectly and feels soft and flexible. Maybe that's why they suggest wearing it to play golf?
I haven't worn this yet, I have to wash clothes before wearing them. I have bad allergies and am very careful not to wear clothes before I have personally washed them. I will report back, and edit my review if this doesn't wash well.
(NOTE) I pleased to report that I machine washed and dried this jacket without incident. The jacket came through like a champ. I think that long term if I wash this jacket often, I may just line dry it to be safe.
