## Description

Made from Smartwool's warmest base layer, these trousers will keep you warm even on the coldest peaks. Features a covered elastic waistband, flatlock seam construction and a midrise waist.

Review: Soft, quality Merino wool that's worth the price. Wouldn't recommend to wear alone as leggings, yet fabric is thick enough to provide true warmth. Really well made with a gusseted crotch and a wide waistband for comfort. At 5'8" I appreciate the generous length. Size chart is accurate. I'm typically a medium but since I'll be wearing these around the house and as pajamas rather than layering, I opted for an overall looser fit in a size large.
Review: I love Smartwool products, and these bottoms are a great base layer. They will keep you warm without inhibiting your range of motion. They're also really soft (unlike the Smartwool 150 which, IMHO, feels like cheap polyester and itches like crazy). My complaint is with the bootie. I have a curvy butt, and these pull way low in the back around my bottom. I'm 5'7, range from 165-180 pounds, and typically wear a 12/M in pants. I ordered a large in these and they still pulled down in the back. I don't want to size up again for fear that the bottoms won't be as snug as a base layer should be. I'm keeping these and will wear them, but I'll also try to find a brand that's a little more accommodating to big-bottomed women. But they do what they are supposed to do otherwise, so I'm happy enough.

I’ve been wearing these under my jeans and slacks all winter. Not too thick, not too thin. They’re quality made and hold up very well, true to size. Thinking of buying another pair!
