Love this brand and have a lot of their apparel like shorts, polos, pants, and pullovers. This is now my favorite by Maelreg. Incredibly soft, great color selection, has some weight to it, and fleece lining provides warmth on cold winter days but not to the point of sweating and discomfort. Excellent fit too. I usually wear M but the S fits perfectly. Great deal right now as well at $19.99 for some colors in my size. Just wish they didn’t put brand name on back of collar. A logo would have been better or nothing at all. But not a dealbreaker. Purchased several of these now.

Love this 1/4 zip

Color: Lavender Heather, Size: 3X-Large

I needed to replace some older 1/4 zips and ordered this with some others. This one by far is the best I received. It's comfortable, stylish and keeps me warm without being too warm. I came back and bought a couple more in different colors.
