Comfortable and light!
Color: Brown, Size: Large
Wanted something that was going to be lightweight but had those longer sleeves because I do still get a tad chilly even on the warmer days. This is perfect, the fabric is lightweight and breathable, the loose cut around the waist adds to the top's "breathability," but it still keeps you cozy and warm on those chilly mornings! The brown is a lovely warm-coffee tone and it hasn't faded a bit in the wash. Very nice shirt to add to your collection!

looks nice, well made and styish.
This was a gift for a friend. It is well made, has a good modern style to it, comfortable to wear, she is taller, and it fits her well. Its a bit warm, so a fall kind of clothing option.
