Purchased this for my son. He digs it. He likes the softness to it and how it still retains warmth. I should have, would have, could have bought one for me, but I failed.....Maybe next time.
This 1/4 zip is very light weight. Almost like a long sleeve shirt but much warmer. And it's soft. Would be 5 stars if the fit was better. The large was painted on and the xl was a bit long @ 6' 180 lbs
One of the best layering shirt that I Have ever owned
It was a Christmas gift for my son in-law. He loved it!
This seems to run a size on the big side. It is however comfortable and well made
Honestly I love it! It's light weight, keeps me warm, comfy on a cooler night, and light enough to not be overheated. Just overall wonderful.
I really like these 1/4 zips. They are very light but warm at the same time. My only issue is the neck portion was a little more relaxed. But still gets 5 stars.
Everything is nice, except the collar elastic is a weird fit, doesn’t fold down well and feels like I’m choking when zipped up
Extremely comfortable and soft - keeps you warm. Casual yet good enough for a dinner date with your wife!
The only beef I have with this shirt the tightness in the elastic around the next. It curls the next material inwards.
