"body": "These leggings are wonderful. They are really comfortable and roomy enough for my larger size. (I am 5'6-ish, and I wear XXL or 16-18 clothes.) I'm an hour-glass figure, so I worried that these leggings would be too small in the derriere, as many women's cuts tend to be. But they went on easily, and they fit in that area without giving me a wedgy and without me having to constantly pull them up over my rump. They are not as bulky as I thought they would be - I can still fit in my jeans without them being too tight. And the fit is just right - it's not like I'm forcing myself into them, so they are easy up/down for things like trips to the ladies room. These leggings kept me nice and warm in the 40-50-degree weather, with just jeans on top; and they added an extra dry layer in rainy weather, with my rain pants. They kept me toasty in the 20-40-degree weather when I had on ski pants. Read more",

"body": "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. Read more",
