Keep you warm and dry !!

Absolutely LOVE these base layers! The merino wool is so so cozy, keeps you so warm and comfy, and don’t smell when sweating in them all day :) I’ll ride for 6-7 hours in these and they keep me dry and comfortable! The zip pocket is a great feature and i love the reinforced high-waisted fit!

Baselayer, running tight, camping PJs.. LOVE

I love these so much. I’ve been moving everything over to natural fibres and I wear these not just as baselayers in cool weather but also as training tights even in warm weather. I size up to a L just for comfort but the way the waistband is constructed allows them to stay up even when I’m jogging. I reach for these over my icebreaker, smartwool, and ibex tights for most things. Arcteryx please please please make a pair of bike shorts or 3/4 length in these I would wear them ALL summer. I’ve been wearing and washing these lots and no issues with wear and tear like some other reviewers say. I’ve been wearing arcteryx since the early 2000s

Poor revised version

Absolutely love my rho merino bottom, so I decided to order another pair. However now it's been revised to the Satoro merino bottom. The fit is almost the same, but the length is 3 inches shorter!! Now the stitching comes across my knee and is uncomfortable. Wish Arc'teryx would stop changing their products and sizing every year. Just make another style in boot cut like the synthetic ones now!

Hello Lisa, we appreciate you sharing your experience with the Satoro Merino Wool Bottom. It’s great to hear how much you valued the Rho version, and we understand how frustrating it is when updates to length and stitching affect comfort. While the fit remains similar, we recognize that even small changes in patterning can make a big difference in how a piece feels during use. Your feedback on sizing consistency and interest in a boot‑cut style is very helpful, and we’ll ensure it’s passed along to our product team as we continue refining future designs.

Love it!

I bought it in nov. 2023 for our trip to Patagonia! I totally loved it under my hardshell pants or even instead of a pijama during the cold nights in Tierra del Fuego. I only wished it was less transparent around the bottom, because I would love to wear it also as normal legging, that's how much I like it.

Like this material, but

I am a long-time user of your products and rely on them for work in high-alpine terrain. I really appreciate the durability and function behind your design, especially in changing weather and technical environments. Satoro Merino Wool The Satoro Merino hoodies are one of my most used base layers. I wear them across multiple seasons in alpine environments where temperature and effort level change quickly. I saw that the bottoms are now available as well. A 7/8 length version would be ideal for ski touring, since it would avoid interference with ski boots and improve comfort.

Holes in crotch

I have used it only two weeks intensely on two skiing holidays and some very cold days in the city, there are (multiple!) holes in the crotch. Insane for this amount of money…

Perfect thin but warm base

I've been wearing this thin base layer through all of fall season and pair it with my kyanite base layers in snow blizzards. Its very breathable, stretchy, holds its form well after many washes, and is such a gorgeous purple. Its thin enough to fit under my outer pants and soft enough not to cause my skin to itch. I definitely love this product! I also love that it fits my athletic build.

Great base layer!

These base layer bottoms have a comfy mid rise waist band, good fit through the legs. I’m 5’7” and 135 lbs and the medium size fit perfectly. I don’t love the pocket on the side of the leg and I was worried the zipper would chaff or rub on my snow pants but so far it hasn’t been an issue. The base layer weigh is great for backcountry skiing, not too thick and not too thin.

Perfect, except for the pocket.

The feel and fit of these leggings is absolutely amazing. They are exactly what I have been looking for for a long time, and I love that they are merino. Sadly they have a huge logo pocket on the leg, which is both useless to me and, more importantly, it means that I can’t really style these with a cute top and shoes to grab lunch with a friend after my run/workout.

Poor quality .

Poor quality….after a month use, wholes appear at the crotch area. Disappointed. l do like how comfortable and warm these are, but never expected quality failure in such a short time.

Hello there, thank you for sharing your experience with the Satoro Merino Wool Bottom. We’re sorry to hear that a hole developed in the crotch area after such a short period of use. While this fabric is designed to offer exceptional warmth, comfort, and moisture management, premature wear in high‑friction areas can sometimes occur, and your feedback helps our teams continue improving long‑term performance. We’re glad to hear you enjoyed the comfort and warmth, and we’d be happy to take a closer look at what happened through a Product Service Request form, which allows our after‑sales team to assess any potential manufacturing issue and guide you toward the right next steps. https://arcteryx.com/ca/en/help/product-service/service-request
