Excellent quality and value
This is my 4th Maelreg 1/4 zip shirt. I've lost a lot of weight and looking for clothing that fits well and doesn't feel like a shirt from China. I found that the quality and fit are excellent. The fabric is soft, well made and slightly heavier than other 1/4 zips I've purchased on Amazon. The weight of fabric gives a quality feel. The styles of Maelreg pullovers are great. I get a lot of compliments on these shirts.

MAELREG Clothing Looks Great!
Love this quarter zip. MAELREG makes some comfortable, sharp looking clothing. Their golf apparel is fantastic. The value is worth it. Their shirts are true to size. I am 6', 215lbs and wear an XL, which fits nicely.

Great for Tall Guys
I got this for my husband, he has a pullover that he has worn for years and it needed replacing. Finding one like this that was lightweight and loose fit was a big challenge. He loves the quality and fabric and its not hot but still helps when their is a breeze or chill. I liked that the color and pattern are versatile for all seasons. He is 6'5 and it actually fits his torso! Just get it!

It’s a hit!
Color: Brown Grey Camo, Size: Large
I picked on of these up after seeing it online. I have multiple Maelreg items and all are great quality. They are my go to golf and casual clothing brand. Super comfortable, soft, light weight, and perfect fit. Olive on the east coast and this color is all the rage in the area. These are some of the best value 1/4 zips out there.
