Preface: I own 4 other long-sleeve smartwool shirts. I bought this because I liked the pattern, but realized after trying two different sizes that it's the sole reason for the cost of this item. The patterned design, plus the areas of elastic-knitting create a strangely tight fit where your shoulders/chest are much tighter than the rest of the shirt, so it's not that comfortable. Furthermore, it's just not that warm feeling even at a 200. I'll wear my 100% merino 250 base layer over this any day. (And save about $30 in the process!)
Great base layer, sleeves are a tad short, otherwise very good all around. Wear it all the time.
This Smartwool shirt doesn’t itch and is good all day long. It’s perfect for layering and the design looks great too!
He hasn't taken the shirt off since xmas morning so he's happy with it! True to size and very comfortable.
I shopped at other stores, and found this Smartwool at REI, it is the best quality i could find
My son in law didn’t take it off for several days. Loved it!!
