I love the fit and feel! They are so comfortable and never get saggy in anyway, just stay nice and fitted. The quality of the wool is great as well.
I decided to splurge on leggings for myself, after buying some clothes for my toddler and seeing how well made and soft the items were. I have been living in these tights non stop ever since they arrived!
I've had both cold (below 10) and very hot (close to 30) weather recently, and these leggings are appropriate for both cool and hot weather. I'm especially pumped to wear these in the summer, as I don't have to live in a pool of my own sweat. For cooler weather, they are not bad even as stand alone (e.g. with an appropriate top and coat), although for below zero I'd probably say you should wear something over them if you're going to be out for a while.
I even wore them to hot yoga, and while of course I still sweat, I was very comfortable both during the class as well as afterward (from both a moisture and temperature perspective). Isn't wool amazing!!
I *love* the crotch gusset, all my other cheap yoga pants pull down, but these ones stay snug around my thick thighs. I am 5'5", 135lb and the medium is perfect for me - snug but not tight.
They also look gorgeous - I got the plum colour, and while it's a bit darker than I expected based on the photos, I still love the shade. As other reviewers have noted, they are a bit sheer (especially bending over), so make note of that.
I really like the simply merino thermal leggings. They fit well and are comfy.
I have only recently discovered Simply Merino and I am SO GLAD that I have! These leggings are by far the best quality merino base layer I have found, the fabric is amazing. I wore them for a week straight, and promptly ordered 2 more pairs. I love the generous waistband, it's so cozy! I often fall between sizes in most brands — for reference, I am 34"/29"/38". I went with medium because I prefer my clothes to have some breathing room, and I'm glad I did, the fit is exactly what I wanted and so incredibly comfortable. Very minimal sagging at the knees even after days of wear. Also, the colours are VERY beautiful in person, I went with forest green for the first pair and they seem to go with everything? :) I originally wasn't sure about the mustard but it is a gorgeous, earthy gold, I love it!
