I hav thick heavy hair! Falls out and doesn’t hold my hair. I believe it would be good for people who have fine hair. Stretched out after one use! Returning getting thicker ones

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.
