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.

Great Vest
this golf vest is amazing. It’s very well-made. It fits well, I’m a double X and I’m 62 and a slice of pizza from 230 pounds. I just love it and plan to buy more. I believe it’s gonna wear very well, but I’ll let you all know in a month or two after I’ve worn it a couple times and washed it a couple times.

As Advertised!
Product arrived promptly & well-packaged (shrink wrapped packaged & enclosed inside additional box). Golf vest was received "as advertised" & appears to be of good quality. Vest was fairly priced & is very comfy, lightweight, stylish & wrinkle resistant. Purchased as a gift for my adult son for his future golf adventures. Size/fit will need to be determined by my son when he prepares for his next golf outing. Very pleased with my purchase & will consider additional purchases from seller in the future.
