I thought that the color was really pretty! And, underarmour stuff,while a bit overpriced, is usually pretty comfy.

Comfortable, Great Fit, and Perfect for Cooler Days
Color: Navy Heather, Size: Large
I bought this in January 2026 and have been really happy with it. The fit was as expected, which is always a big plus when ordering clothes online, and it feels comfortable right out of the package.
What I like most is that it’s nice to wear when the weather is a little cooler, but it doesn’t feel too heavy or too hot. It works well as a light layer and has been a good option for those in-between days when you want something with long sleeves but don’t want a thick sweatshirt.
It also looks good when wearing it, which makes it easy to use for more than just workouts or casual lounging. The overall style is clean, and it has a nice look without trying too hard.
Overall, this has been a great purchase. If you want a comfortable quarter-zip pullover that fits well, looks good, and works well in cooler weather without overheating, I’d definitely recommend it.

Excellent Quality and Value
Color: Marina Blue Geo, Size: Large
The size is appropriate as is the fit. I like this garment a lot because it flexes with body movement. I golf in it and there is minimal restriction. On sale it is an excellent deal. It is both warm and comfortable.
