Amazing fit!

I got these last winter and I Love how they are thick and hold me in... but I legit put my finger through the pant leg. Im so sad because they are my favorite. The girls love this color combo too. Im not sure what to think about the tearing of the pants but before then I felt like they kept me super warm, and dry while running in Chicagos cold winters. These are so good that when you open the pocket you can feel the actual temps outside of the pants so you want to hurry up and zip them back up. I will replace these but I will also try not to be so aggressive when putting then on and off. If they didn't rip I would have given these 5 stars!

Warm and stretchy

I bought this along with the matching shirt. At 5’7”, 120lbs I bought a large. Perfect fit! Super warm and stretchy.

Snug fit!

I bought these bottoms to replace a very old pair of the same ones. My old ones are probably close to 20+ years old and were likely close to first generation of this product. The old ones are still in use but i wanted another pair on standby. The newer model fit more snugly. I weigh less than i used to and still needed to size up from a small to a medium. Nearly everything else i wear from Arcteryx is size small or 4 short in pants! Thusly, if you have an athletic body type, my advice would be to size up. These fit snugly and they are warmer for their weight than i thought they would be. They are a good mid range base layer that should easily fit under most pants.

TEAR on day 3 of snowboarding with them!

I just bought these and have snowboarded them three days now and when I got home I was super shocked to see that they had a hole on the butt…I couldn’t believe it. Just makes me think the material is not all it’s said to be for the cost that just shouldn’t happen. They fit great and feel amazing on but the tear that happened on only day 3 of riding in them has be very disappointed and I will be returning for a refund or possibly and exchange to try them once more…

Poor quality seems

I bought my Rho bottoms to wear as a base layer on some easy fall hiking. I am so disappointed in the quality of these pants, I expect much more from arcteryx. Pros: they are extremely comfortable and do provide the warmth I was looking for. Cons: multiple seems started to fray and come off the pants within two washes/four wears. These bottoms will not last.

Ripped on the first wear

I would not recommend these as a base layer for snow sports. Originally was hoping to use these for yoga, walks, and for snowboarding. On the first wear, a giant hole ripped in the rear of the pants. I have had plenty of other brand leggings last many years. This is definitely not a premium product, I would avoid this one.

LOVE THESE, minus the weird pocket.

I love these bottoms, I have 3 pairs! I use them primarily as a base layer while backcountry skiing but I do have one question: what's with the pocket? If there was no pocket these would be perfect. The description says "for a smartphone" idk why you want a smartphone inside a base layer where you can't reach it without taking off the top layer? The pocket material is not stretchy so to have a piece of non-stretchy fabric sewn into an extremely stretchy material makes for some weird pulling.

Great for work

I been using lots of my arctryx gear under my work gear, and by far best money i spent on base layers that keep me warm and work with me. My coworkers chirp me about wearing arctryx to work but it does the job of multiple layers of sweaters and insulated pants that i would have been wearing. The site im working at is in the mountains, snow, cold winds, changing weather. Lots of walking, climbing, active working. These bottoms definitely keep up.

Definitely not the Rho layer I was expecting

These kinda suck. I had an older version of the Rho bottoms (mind you, only about 2 years old) that were perfect -- thick, warm, durable. Wore them for everything until I had them stolen with some other luggage. Now, trying to replace that pair, these are not it! Way way thinner, way tighter cut, definitely not as warm and versatile as I was expecting. I wish Arcteryx would quit switching up products and stick to what's good.

Hello there, thank you for sharing your feedback on the Rho Bottom. We’re sorry to hear that the updated version didn’t meet your expectations, especially given how much you valued your previous pair for warmth, durability, and versatility. We understand how frustrating it can be when a trusted piece changes in ways that don’t align with what you loved about the original. Our product team continually refines designs to balance performance, fit, and intended use, but we know that changes can feel like a step back when the earlier version worked so well for you. Your input is invaluable, and we’ll make sure it’s shared with our design team as we evaluate future iterations. If you’d like, we’d be happy to recommend alternative bottoms that offer a thicker, warmer construction closer to what you enjoyed in your older pair.

Warm and comfortable

Warm and very comfortable - stretches without binding. Loved my upper liner so much I bought the bottom! Recommend you check the fit when you get it - if you are in between, recommend going down in size as it's very stretchy and that way it won't bunch up under your overlayer(s).
