Great hoodie, great price!
Color: Light Grey Heather, Size: Large
I love this hoodie, if you're thinking about buiying, just do it. Watch the price if you can for a while as this brand tends to go on sale frequently. I got it for a great price and its well worth it. I really like the look and quality, most importantly the price!

Great style and comfort
This is a fantastic sweatshirt! Made from a high quality fabric this shirt doesn't even feel like what you think of when you think "sweatshirt". It has a sophisticated design pattern and a great style perfect for golf or even to wear to the office in a casual tech company. My husband has done so and got many compliments and requests to tell him where he got it!
It is true to size, with a cut that fits a variety of body sizes perfectly. It is very flattering, comfortable, and soft. It just looks great.
It washes easily, stains do not set and neither do wrinkles. I intend to buy more of these in other colors.

Excellent Midlayer for Golf
Color: Light Brown Heather, Size: X-Large
My dad has been wearing this M MAELREG hoodie for about a week now, specifically during my early morning golf rounds where the temperature sits in the low 50s. The fit is true to size with an "athletic" cut, meaning it’s tapered enough to look sharp but has enough stretch and light enough to allow for a full shoulder turn during a golf swing. The cost is also a lot lower than some of the tech golf shirts out there. Overall this is a great shirt for golfing with an expensive look.
