Ample room for my larger figure, great cold-weather gear

Old House ParentsAugust 26, 2024

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

Not too weighty, still warm.

Antréa FergusonJuly 31, 2025

I love using these because I was able to layer with them and it was the perfect durability the perfect fit the perfect thickness and I haven’t washed them yet so I don’t know how they do in the wash, but they were good. Not too weighty, still warm. Read more

Dependable Smartwool Quality

CindylouOctober 16, 2025

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

Quality but not for curvy gals

Happy or NotFebruary 3, 2025

The material is of good quality and isn't itchy. I knocked off a star because it was short-waisted. While wearing this under a pair of pants, I was worried all day that it was slipping down. Read more

Very warm base layer

karenDecember 28, 2024

These fit really well under jeans. They provide enough insulation to protect against winter winds. They run just a little short in the rise & a little small through the hips. I wear a size 31 x 32 Levi’s jeans - the large fits me comfortably. I’m 5’09” & weigh 150 lbs. Read more

Breathable, warm, soft, used for yoga

Colleen DrakageJanuary 7, 2024

My husband is on a big natural fibers kick and while I support this, I have been hesitant about the prices. I have only worn once for a full day of yoga teacher training and they were so great. Much more breathable than all other polyester/spandex type “high end” pants. They stayed up on my natural waist and were soft and comfortable all day. I am a convert. I will have to report back after multiple wears. Hoping they will hold up Read more
