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.
