Working man's best friend
I'm not a hiker or a snowboarder. I'm not likely to climb Everest or compete in a dog sled race across the straits of Alaska. I suspect a lot of you that have happened past this review aren't either. Probably, like me, you work in the cold in the winter, maybe sit in a deer stand on the weekends. I'...

Not as well made as they used to be
I have always loved merino wool stuff, namely smart wool stuff. I have several base layer shirts that I have had and used for years. They are durable and well made, and will last man more years. Because of this, I decided to buy a pair of 250 bottoms. Very comfy, standard long john bottoms. My ...

Very comfortable material
Bought these for my husband to wear on an upcoming motorcycle trip. He has not worn them yet, other than trying them on. He said they were very comfortable and he thinks they will provide extra warmth under his motorcycle pants.
Have multiple pairs would buy again
Have multiple pairs great for layering or lounging I wash inside out and air dry. Will last for years!
Needs Crotch Reinforcement
Good fit but seemed a little skimpy reinforcement in crotch area. Other than that, at least this has a fly for bio breaks. Probably good for days 25+ degrees.
Would buy again
Love these!!! by far my favorite base layer bottoms!!!
The best base layer ever
Under ski pants, nothing feels better than Smartwool. They look good too.

Greatest Brand Ever
My wife and I are climbing Mt. Kilimanjaro in late June and this purchase completes my hiking gear for the hike. I wear my 4 x 1/4 zip 150 & 250 weight tops all the time and recommend Smartwool to any one and everyone.
I may need a second pair.
Perfect fit, great base layer for new England winter, waiting for the bus or walking to work.
Love the
My husband wears only wool base layers now (me too) for XC skiing. These are perfect. And nice to get green. Sick of so many black pairs.
Great product with one slight adjustment
I purchased this for my base layer. I do wear 3/4 pants but wanted an added layer on cold days. I like the product but my one complaint (or suggestion) is to offer a 3/4 or short/ tall versions. I'm a short 5'10" and a medium was too long. I originally purchased a large and they were swimming in me.
