Cozy Days

I purchased this fantastic Smartwool Classic shirt knowing that my 15 days in the Northern Rockies of Alberta Canada were going to be cold. I was cozy in this shirt on early morning hikes and a few snow showers I was in at higher altitudes. This is my third Smartwool classic and they are my comfort companions when hiking and just out and about.

Uncomfortable
JD7971 year ago
Wanted a merino wool base layer and got this on sale for $35, but even at that price I still think it's not a great deal. The fabric is a bit scratchy and uncomfortable, which is kind of a no-go for a base layer.

No Stink - 3 days.
1 month ago
No Stink - 3 days of light hiking in Canada. Do prewash as it is a little itchier than other wool blends. It does shrink a tad with wash - so buy it looser than what you want it to fit liken. I purchased a L as it fit great in the store - but after washing it had to go back and buy an XL.

Inaccurate color
3 weeks ago
I am writing to express my disappointment with a recent purchase. The product's actual color significantly differs from what was displayed on the website. I ordered what appeared to be a yellow base layer (marmalade), specifically for a gift, but the item I received is orange. Accurate product photography is crucial for online shopping, and in this instance, it led to an incorrect purchase. While I personally like the color orange, it is not what I intended to buy. I will be returning the item.

Good for a cool weather hiking
1 year ago
I've used this shirt as a base layer for cold weather backpacking for five trips or so now, and it has served me well. I've been able to pair it with a rab fleece jacket, and a windbreaker and have been able to survive some cold conditions. It isn't going to fit as tight as an under armor synthetic base layer, but it's not supposed to, so don't worry if it doesn't have a skin tight fit.

Comfortable and Warm
8 months ago
So far I love this shirt. I have worn it on a few alpine trips, one of them overnight, and several hiking trips and I have found this to be an excellent layer. It’s plenty warm on cold nights yet not too warm when the sun shows up. The material is thin but has a quality feel to it. I find it very comfortable too and look forward to seeing how long it’ll last.

So far comfy
2 years ago
Haven't had a chance to put it through the rigors of it's intended use as a travel base layer but it performed well on a chilly night under a down vest. Which, now that I think about it is pretty good for how thin it is. The temp was high 30's and I was on a patio for hours late into the evening and was comfortable for most of the evening.

This is the best long-sleeved crew made

Outstanding design and manufacturing quality. The black is a deep black color and the material creates a core warmth that other materials lack. Wonderful.
