Great lightweight fabric, good design
Color: Grey Green, Size: Small, Color: Grey Green, Size: Small
This hoodie is a great athletic top. The size small fits my husband well, although it's a little loose in the arms. So if you have a leaner figure, you may find it a bit baggy. But the fabric is fantastic, a high-quality performance fabric that seems breathable and the UV protection is a great bonus. The sleeves are long enough to make good use of the thumb holes in cooler weather, and the color is a nice neutral, gray-green. For reference, the size small has a chest of about 42" (measured just under the sleeves) and a center back length of approx. 25".

Great Quality and Look
Color: Grey Green, Size: Medium
21st century materials are here to save us! :) M Maelreg does a great job utilizing those materials to the best of their ability. I've really become a fan of just about anything that they make, and this shirt is no exception. It's made from the very popular 88/12 Poly/spandex blend that has become ubiquitous in the fitness/active industry because of its amazing tensile characteristics- wicking, quick dry, UPF, and extra comfy against the skin. You get all of that here and a no-frills, really beautiful color to go along with a fit that is exactly true to size. I took the more form-fitting version for my 5'10" 175 lb. frame (I've found both L and M work from these guys, M for a more tailored look) and it's exactly right- enough room to move around comfortably and breathe, not so tight that it's hugging my belly. It's super lightweight and really easy to launder (I hang dry mine to prevent pilling and wrinkles), cold/low and a medium/low heat iron to rid those stubborn factory wrinkles and you shouldn't ever need to iron it again. Another great offering from the folks at Maelreg.

Just like the big brands!
Color: Light Dark Blue Grid, Size: 3X-Large
This hoodie is very good quality. I would say it compares to many of the Columbia or Northface type. The only problem that I encountered was that the sleeves are very long, but that might be a me problem because I am pretty short. The hoodie is very lightweight so it can even be worn on semi warm days and really is mostly used as a form of sunblock. I feel like the sizing is very true to size and if anything there’s a little extra room. The price is just right since it’s much less expensive than the big brands and it holds up after being washed several times. It’s very comfortable and breathes very nicely as well.
