Soft & Comfortable. When you think wool, you may think scratchy, but MERIWOOL's Merino Wool clothing line is far from it. We only use superfine 18.5-micron 100% all natural Merino wool responsibly sourced from Australia to ensure your comfort all day long with absolutely no itching! Sustainable & Renewable Resource. Feel good knowing that what you are wearing is beneficial to you and also good for the Earth: Merino sheep shed and regrow new ultra-downy coats every year, making their wool a highly renewable resource. MERIWOOL is ethically harvested from sheep without loss of life. Limitless Layers. Merino sheep have adapted to all kinds of weather including freezing winters and scorching summers. Their wool keeps them warm when it's cold, cool when it's hot, and that inspired us. MERIWOOL's superfine Merino wool clothing can be layered as needed, but won't weigh you down or hold you back. Wicking. When you're out exploring all day, there's nothing more uncomfortable than a sweat-soaked shirt sticking to your skin. Merino wool absorbs sweat from your skin and then releases it to the air in a process called "wicking". Its natural anti-bacterial properties resist odors and keep you dry and comfortable. Rest assured that MERIWOOL's got your back, even when you're out for days in the wilderness. Machine-Washable On Cold Setting & Tumble Dry On Low Heat With Like Colors. Easy to wash, wrinkle-resistant, quick to dry, and with very little maintenance required, Merino wool is ready whenever you are for your next adventure. Warranty: Your MERIWOOL garment comes standard with a 1-year limited manufacturer's warranty which covers manufacturing/material defects only. It does not cover wear and tear due to normal use, abuse, negligence, or unapproved alterations. To process a claim, please contact the authorized partner you purchased your garment product from. Review: Primera capa - Buenísimos como primera capa, no pican, no guardan olores, un must para la nieve Review: THESE ARE AMAZING. - When I took these out of the package, I was skeptical about them being 100% wool, simply because of how soft and smooth they are. I did a burn test. They ARE 100% wool, and they are so damn comfortable! Because the wool fabric itself does not contain any spandex (the waistband has a little spandex strip though obviously) they do not form fit to every little curve and crevasse the way spandex leggings do, but they are a very dense, fine, tight knit fabric that actually clings nicely to where you want it to without being too tight. They stretch considerably yet retain their shape well and are not baggy. I ordered a small. I am 5'2", 115 lbs and curvy with 24" waist and 38" hip. I was worried about the waistband being too big since I had to order a small insted of an xs so it would fit my hips. These are not really high waisted, so the band doesn't quite come up to the smallest part of the waist so it actually fits perfectly and is not too big. I wanted them to fit as loosely as possible without being too big because the more thinly they have to stretch to fit, the less warm they are. The ankles are just a little bit tight when putting your foot through but are fine once they're on and it's not a problem. They are thick and warm and very well made. Someone commented in the reviews that they are not a heavyweight wool, and that's straight up bull***t. These are a 400g knit fabric and it is hard to find anything heavier than a 320g in 100% wool leggings that you'll still pay literally double what you pay for these. They are very soft and not super scratchy like I'm used to wool being. Perfect for layering or wearing on their own. An excellent quality garment that I have now bought a second pair of (and another for a friend, and the 400g heavyweight shirt), as I will be wearing these every single day during the cold months. WORTH THE PRICE. Dont ever put wool in the dryer! Lay flat to dry. BUY THEM! ## Features - PACKAGE INCLUDES: 1 – Women’s Merino Wool Thermal Underwear Leggings in Black / Small | MATERIAL: 18.5 Micron, 100% Merino wool, 400g/m2 | FIT: Fitted - SUPER SOFT: 100% all natural superfine 18.5-micron Merino wool ensures comfort all day long – no itch!

I got the thickest ones and they keep me warm. For the truly cold cold days in winter. I would wear the normal thickness for skiing but the thick ones if Im not going to be as active- theyre almost too thick for skiing i think unless its -20 F out. Highly reccomend. theyre soft, a cute color, material quality is great.
