How to Layer Merino Wool
6 reasons to choose merino wool
-
Temperature Regulation
An active fiber that thermoregulates
Merino naturally keeps sheep warm in temperatures as low as -4℉ and cool in temperatures up to 95℉, making it the perfect choice for performance apparel as it reacts to changes in your body temperature. The natural crimp in wool provides durability and elasticity, while hydrophilic properties wick moisture and thermoregulate the body to naturally cool or insulate you relative to ambient outdoor temperature.
-
Moisture Management
Merino won’t sweat it
The ultra-fine merino fibers we use in our apparel are naturally breathable, which helps prevent you from feeling clammy, damp, or sweat-soaked when you’re exercising. While synthetic fabrics can wick away sweat, merino keeps the body cool during exercise by trapping that moisture and releasing it as vapor before it even condenses on your body.
-
Natural Deodorization
Minus the unpleasant odor
Even if you wear your merino layers for a whole week on a grueling trek, you’ll be able to drink a celebratory pint at the end of the trail without bringing a cloud into the pub. Lightweight merino is an ideal layer for seasoned travelers, commuters who don’t want to change after their rides into work, and anyone hitting the road with limited luggage space or no time for laundry.
-
Unbelievable Softness
Incredibly Comfortable
What is Merino wool better at than traditional wool? It’s super-fine and soft. A single Merino wool fiber is ⅓ the diameter of a human hair. It’s so fine, actually, that when it brushes up against skin, it bends out of the way. It can’t be prickly like other wool fibers because it can’t stand up to the weight of itself. So it’s soft. Really soft.
-
Natural Sun Protection
Ever Seen a Sunburned Sheep
Merino fabrics are naturally resistant to UV rays without the need for chemical treatments. Our chunkier mid- and heavyweights offer UPF 50+, while our lightweight range offers around UPF 25. That means that while your muscles might feel the burn as you push for the summit, your skin most certainly won’t.

100% Climate Positive Wool Sourced
Merino wool is Natural&Sustainable
Because our Merino Wool grows perennially on our sheep's backs–no different than the hair on your head–Merino Wool is widely considered the world’s most sustainable fiber. Our premium Merino Wool fleece is shorn once a year by skilled shearers. The sheep’s wool grows back over the course of the following 12 months, producing a new batch of fiber destined for Climate Positive clothing material.

Much cheaper than popular advertised brands. Works for me. Not high waisted if thats what you want. But good.

These are great! Finally, merino wool undies that are affordable! Stayed dry my entire 13Hour shift and didn’t get a wedgie once. I’m around 160 lbs and got a large - fit is perfect. Another plus is they are Tagless. Just wished they offered more colors or patterns. Overall I’d buy more!

While I love merino, and the underwear itself seemed an okay quality, I was taken aback that the "2 pack" that I bought was only 1 piece of underwear in the package.I chose this listing because I thought the 2 pack would have been cheaper than the amazing Icebreaker underwear. But frankly, this is poor value for money for not even an equivalent level of product quality and softness. Super disappointed ☹️

Edit: after having them for almost half a year and tried more washing styles, I found that when I wash them on a regular cycle instead of hand wash cycle, and temperature on warm instead of cold, and they stay fresh through the day.I have several pairs of merino underwear from different brands, and they are very good. These underwear feels great, breathable, soft, but it start smelling after half a day. I am healthy, and normally don't stink, but these underwear after morning shower, by afternoon or evening smell like I haven't showered for a week. This does not happen with my cotton or synthetic underwear. Only these. My other merino underwear smell like they haven't been worn after 24 hours of wear.I gave them a couple of months of wear and wash with different detergents and settings, but it didn't help the stink. I mean, they smell fresh after wash and when I put them on, but they stink after about 6-8 hours of wear.

I bought these to try wool panties, because I was a little skeptical, but I’m sold!!! These wash/dry and wear great (tiny bit of shrinkage and collect lint), plus they don’t ride up at all. They really resist sweat and don’t get hot, even in the hot summer. The gray color looks a little weird in the photo, but it’s more of a true oatmeal, very pretty. Buy these!

Great fit, wash well, and feel great all day. Order a size down-there definitely run small! Would be 5 star except for running small.

These underwear are comfortable and the fit is flattering, however it’s been only a month and a half and it’s already getting holes. The fabric is thin enough that when you go to pull the underwear up it can cause a tiny hole to appear. I can’t compare them to other wool underwear because they are the first I have tried.

I first bought a set of these just testing the waters of wool undies. They're usually so expensive, but these were more reasonably priced at $15/pair. Turns out they're super comfy, and the magic of wool is still legit in underwear - and I live in Florida, so I'm mostly wearing these in hot weather. I eventually reordered when a trip was coming up, and I wanted to pack really light. I brought all four pairs of these for a 7-day trip with the intention of washing in the sink and air drying. That plan worked great! And I really put one pair through the wringer, because when I got to the destination, I realized I had not packed any underwear for running the half-marathon I had planned. Oops. Every runner knows: nothing new on race day. But I don't like how running commando feels, so I didn't have a choice: I wore a pair of these for actually about 14.5 sweaty running miles that day. And! I had NO chafing, NO uncomfortable feelings... They performed great. When I got back to the hotel I just wore them into the shower and washed them in there. All of them hung dry in a little more than overnight. So yeah, I'm a big fan. Very tempted to buy a bunch and wear them all the time, but I really wish there was a beige/pale person invisible option, and some other colors. So I'm still deciding.My hips are 41" at widest and I wear these in my Amazon recommended size large. I am tempted to try a medium though because one set is too big.Sizing is inconsistent. My first set was the black and dark blue and they fit great in my Amazon recommended size Large. They didn't shrink in the washer. My second set was the black and gray in the same size, and they are big. (See pics.) I *tried* to shrink them in the dryer, but it didn't work. They are wearable though, but they do ride up after I wear them all day.The only other thing to note is that if you want to wear pantyliners with them, you're going to need to rough up the liner area. I literally took some sandpaper to them! And yes I know that liners can seem to defeat the purpose of wool, but I sweat a LOT and really like the fresh feeling of a clean liner. They are not uncomfortable to wear without one after roughing them up either.

These wool undies are good. They are quality and affordable. You basically get two for the price of one elsewhere. They do run about one size small. I’m usually a medium. I preferred a large Ans they fit like a medium. I like that the back butt area had enough fabric so they don’t ride up. Other brands of more expensive woman’s wool undies ride up and I have returned them. They are soft and wash well in warm or cool water. I tumble dry on gentle low heat and zero shrinkage. They have 12% Lycra spandex to give them a little stretch. The rest is merino wool.
