I love this so much
3 years ago
The zip/funnel neck isn't quite my style, but I want to wear this all the time so I just roll with it, knowing it doesn't quite match the rest of my outfit. Cozy layer, not too hot, not too cold. Even if I have a sweaty day, it airs out beautifully. I have the crew neck of the same 185 line and the neck is uncomfortable. I wish I had sent it back a year ago and gotten this. I will probably buy another one soon.

Low quality material

I bought this a few months ago but it finally got cold enough here to wear it. But there is a hole in the sleeve. I washed it according to directions and it did not snag it on anything.

I got this to wear for late season backpacking in Minnesota and I have been so happy with it. The fit is so much nicer than my other Merino shirt (SmartWool) which is has a nice feel but too short in the waist and this one has such a perfect fit. It even looks good.

I've worn this as a shirt, under another shirt, and as pajamas. It's very comfortable and not itchy at all.

great!

This is also not usually my style — specifically the collar— but it is so comfy and the fit is excellent. I don’t love the feel of the zipper, but I do love the flexibility.

Poor quality and customer service
2 months ago
Bought two of these shirts, washed and wore each once and they both developed small holes in the front and back. Took to REI store for return (over 1 year after purchase) and was denied a return for the amount I paid, only offered about 15% trade-in value. Disappointed in quality of REI brand and declining customer service. Will be finding alternative retailers in the future.

women's half-zip merino base layer
9 months ago
Fabric is soft and smooth, top is well-made and fits very well. Color is as described- a soft heather-like blue. The collar shape and zipper are comfortable and provides some temperature control. I'm VERY happy with this top/shirt, (looks, comfort, fit, fabric weight) and was DELIGHTED to find it on sale! win-win!
