Review: Size up unless you want a tight fit. - I sized up. I would normally order a medium. The stated waist measurement on medium was good but the hip measurement was small. I ordered a large and I am very happy with the fit. Since there is no spandex (100% wool) they don't stretch much. The large are quite comfortable and will be great for hiking.
Review: Replace ALL your other leggings! - I get cold easily and am trying to gradually replace as many of the synthetics in my wardrobe as I can with clothes made of natural materials. So when I saw these leggings while doing my Black Friday shopping, I gave in to temptation and bought four pair - two heavyweight and one each in medium and lightweight. Yes, they're in different colors (black, grey, and blue). What I LOVE: They're cozy soft, like a high-quality fine-knit (superfine) merino wool sweater. They aren't itchy at all, and they breathe like they're not even there. The heavyweight ones are sufficient for the freezing temperatures at my sister's place in the mountains without being too warm for the slightly-warmer temperatures at my parents' place. They all look great, sleek and streamlined without the plastic sheen of synthetics. If you do medieval reenactment, like I do, they'll work perfectly for it too, as long as you can cover or ignore the company logos at the hip and left ankle. The free pair of socks that come with them are a basic grey but feel almost pillow-soft. What could be improved: I got XXL, because my measurements are borderline between there and XL for the company's size guide (L/10-12 in normal store sizes). The leggings are a little looser than they need to be, though the nice thing about wool knits is that you can't tell they're big unless they're way too big. I'll probably get XL for my next order, but only because I like the waist to feel a bit more snug than these are. (I can add a drawstring to fix that.) There's a seam about 3" above the ankle that I wish were slightly less visible, though it's not enough to make me look for a different style. An option with pockets would have been nice, even though it would mean losing the seamless line along the outer leg. But these minor issues don't even add up to any significant dissatisfaction. I'm going to be living in them all winter long and will at least be able to wear the lightweight ones in the summer. As well as wool breathes, even the heavyweight ones will probably be more comfortable than synthetic ones in the summer.

## Questions & Answers

**Q: Won't merino wool feel itchy? And what does 17.5 micron mean?**
A: 17.5 micron superfine merino fibers are finer than human hair — too fine to feel itchy, even on sensitive skin. Standard wool (25+ microns) causes irritation; this doesn't. OEKO-TEX certified, tested against 100+ harmful substances.

**Q: How do I wash and dry it to keep it looking new ? Will it shrink or lose shape?**
A: Machine wash cold max 30°C, delicate cycle, inside out. Lay flat to dry — tumble drying permanently damages merino fibers. Store clean and dry; keep merino in sealed bags to prevent moths. Wear 3–5 days between washes — merino resists odor naturally

**Q: Which weight should I choose — 165, 250, or 320 g/m²?**
A: 165 g/m² — active pursuits, travel, spring/summer, 40–60°F. 250 g/m² — cold weather, most outdoor activities, 25–45°F. 320 g/m² — frost and low activity, 10–35°F, extreme conditions. Rule: the higher the activity level — the lighter the weight

**Q: Where does the merino wool sourced from and is this product certified?**
A: Our products are made from Australian merino wool, RWS certified — independent farm audit confirming animal welfare and land management standards. Every component tested against 100+ harmful substances under OEKO-TEX Standard 100.

**Q: Does it fit true to size?**
A: Choose your regular size. For a snug layering fit under jackets or ski gear, size down one

### ⭐⭐⭐⭐⭐ High quality, thick gauge wool at budget friendly prices
*by Z***R on January 24, 2026*

Sooo glad I bought these for base layering before the big snow storm! I do a lot of winter beach walks in the NE and need to layer up due to wind and extreme cold temps. I wanted a heavier gauge wool (320) to keep my legs warm while walking. These are better than my old Smartwool pair at half the cost!! Really impressed with the high quality wool used and the budget-friendly pricing. Great for moisture wicking, heat retention and also odor control, which means longer wear times between washings- great if you’re backpacking or extended hikes. High quality, non itchy and not bulky for layering. Very cozy feeling too- you can wear them around the house as a single layer like sweats, but a lot less bulky. Haven’t washed them yet but will hand wash in cold water with Woolite to preserve fabric and air dry. You can machine wash them on cold/gentle cycle too if you want, tumble dry low. I am 5’3” 115 lbs and the small fits perfectly. Couldn’t be happier with my purchase! also comes with thick wool socks that keep my feet warm and dry. Stay warm!
