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.

Materials are very light weight, not sure if it will hold up
This jacket is very light weight, made of very thin nylon type materials. Concerned of its abrasion resistance. Only inside of sleeves are fleece lined. It is very comfortable and fits well to size. Don’t have enough cold weather yet to test, so we’ll see. Not sure this is a great value for the money.

A Very Nice Lightweight, but Warm Jacket
I was surprised at how light this jacket was when I took it out of the nice box it came in. Despite its light weight, it is still a very warm and cozy jacket. The lining of the jacket is a soft fleece, which is very comfortable. It also allows for easy layering with sweaters and shirts. The lining is very warm and cozy; it's moisture-wicking, as well, which will keep you nice and dry. The outer shell of the jacket is perfect to keep that cold wind out! It also helps with the sun, with a UV protection rating of 30+. It seems very durable, but it is not bulky at all. In fact, the whole jacket stretches a bit for even more comfort and a good fit. Whatever climate you live in, this jacket will provide you warmth and comfort without bulking you up like the Hulk. it's a great little jacket to keep in the car or at the office.
