I’m Team Maelreg!
Color: Dark Grey Heather, Size: 3X-Large
I’m a huge fan of Maelreg! I’ve purchased numerous polos, a hoodie, a pair of shirts, and some golf pants, as well as two of these quarter zips (and I currently have a third one in my Christmas list). I love the way they fit and the way they look. I’m a bigger guy too, so it’s not easy to find fashionable “ath-leisure” apparel that doesn’t make me look like a popped can of Pilsbury biscuit dough. The only thing close to a complaint I can think of is that these are a lightweight weight material and the collar doesn’t want to stand up on its own. I wish Maelreg made a medium weight version with a little sturdier of a collar, but that’s just me.

Nice fit!
Color: Saxony Blue Melange, Size: X-Large
Great fit. Very comfy. Not too heavy. (Think late spring, early fall weather.) Material and stitching seems high quality. Slightly stretchy fabric. We’ll see how it holds up to wear and washing, but so far so good. I’ve already purchased another in a different color.

Fits true to size and good quality
Color: Black Grey Heather, Size: Large
I gave this 5 stars because I was pleasantly surprised by the fit and quality. The zipper is nice, it zips firm, it's not flimsy like a cheap zipper. For reference I am 5'7", athletic build, and 198 pounds. I ordered a size large and it fits perfect. I will buy more for sure.

Great fit, excellent material. Will buy more!
Color: Cobalt Heather, Size: Small
Great quarter zip comparable to the high end designer brands. Buttery material, well fitted. Runs a bit big so I sized down and it’s a perfect trim cut fit. Will buy other colors. Would like to see some patterns in addition to the solid colors. I’m 5’10” 165lbs and small size fits perfectly.

Perfect for the gym!
Color: Cobalt Heather, Size: XX-Large
I bought 2 (black and blue) and wear them to the gym weekly. They wash & dry very well! They are nice enough for casual wear too. I’ll probably buy a 3rd color soon!
