Well, it’s not really a sweater, but I keep calling it that because it’s warm, soft and so comfortable. I have a black one that I have worn constantly and decided to get the grey one since I love my black one so much. I usually wear this sweater over a short sleeve wool shirt and then if necessary add a vest and/or a coat. I absolutely love how soft and comfortable it is and how it brings just what I need in a long sleeve layer. And..it looks great on!
I love this 1/4 zip so much that I just ordered a second so I’ll have both colors. It’s been a staple during our cold winter. I did size up. I’m a solid medium in other tops, but was concerned about the “slim fit” so I ordered a large. It was the right choice for me. It’s soft, warm and washes well (I usually hand wash and air-dry my merino). Great price! The “x” brand has an identical 1/4 zip for double this price, on sale!
Definitely thicker material but very fitted. Almost returned it. Tighter than another shirt-sleeved shirt I also purchased.
Really nice top. Nice cut, great length. Very flattering.
It's really comfortable, keeps my body temperature regulated on these days that go from 39 to 60 and it washed well.
