Customer Reviews Arc'teryx Rho Heavyweight Bottoms

Good quality

Very good extreme weather base layer. I have had mine for over a decade. Still wear them in Alberta winters. I can layer with Alpha Pants and this is often enough to ski in. They are extremely warm and not the best for high output activities. They have a little pocket on them that I have never used for any reason.

If these fit you they're very comfortable and pretty awesome, product is excellent; however, I ordered from the outlet site so no returns and unfortunately the inseam is way too long for me, lots of bunched up material, I'm 5'7". I see the sizing chart references a shorter inseam version but I don't see where these are actually available to purchase. A 30" inseam would be ideal for the vertically challenged folks out there such as myself.

Really nice comfy, warm layer for climbing and skiing on cold days. Also nice for running or biking in winter. Seem to be holding up really well too.

These base layers are phenomenal. The comfort is unmatched when it comes to base layer pants like these. The material is super soft and comfortable next to skin and is a delight for really cold days or nights. I find myself camping in the cold quite often and I'll wear these to bed every time and sleep like a baby. I've had them for many months now and they've held up very well. No noticeable wear at all. The pant is quite stretchy too and feels like high quality material. They are great for time around camp once the sun goes down and things cool off. I've worn them climbing a couple times and for single pitch cragging in the cold, these are a great. Get a little warm if you're moving around a lot but for skiing, these would be great. Overall, I have been super impressed by the comfort and warmth of this pants. If these ever blow out I will most certainly be scooping another.

Have had a pair of black ones & use them every day as well as a pair for skiing. Skied in Eastern Canada -20F used them under a bib.Also keels your bottom warm on the chair. A winner!

These are a great base layer to be used with a shell pant. Used them this past weekend skiing in Vail where the temperature on the first day was 40 and the second day was 25. Performed very well.

Been wearing this for while working in the Rockies and has keeping me warm! Great article of clothing!

Great product. My only complaint is the thigh pocket zipper sticks out through the pants I wear over them. They keep me nice and warm. They are thicker than most thermals but not bulgy at all.

I have two pairs of these and I have to control myself in order to not overwear them as I literally live in these all winter. Thick and warm, they are great against the skin for cold activities without a lot of cardio and sweating, like downhill skiing, belaying or really cold days (below -10c). These things are great and then at the end of the day you can just drop your shell and wear these around all evening until bed. No need to shower and change, just lie around the house in these evening lounge pants. Highly recommended for these activities, I love mine.

I have gladly used RHO bottoms for many years, and now got a new pair of thicker material. This is ideal to be worn under shell pants to prevent cold when sitting in chairlifts or breaks between touring. The lighter model is too cold and always had to wear extra long-johns under shell pants, but this heavyweight material solves the problem completely!

I tend to like a slightly thicker base layer on my legs and these are the ones. Breathable, warm and super comfy.

Bought them for skiing but wear them around the house under a pair of shorts they are so comfy. They fit nice and tight, are quite stretchy and long. Great if you are a bit taller. Super high quality feel and worth the money over merino if you ask me.

These are my favorite base layer pants. Well worth the cost!

These are a fantastic base layer for low and high output activities where heavy insulation is needed. Paired with the Alpha pants these kept me very comfortable on the mountain at 20F (5F windchill).

Verry happy! It's fit perfectly Very worm and confortable!

Muy clido y elstico. Permite moverse con facilidad y desliza muy bien bajo un pantaln de goretex. Es el tercero que tengo y este ultimo talla manifiestamente ms pequeo que los anteriores.

The Rho heavyweight is really well made, super warm and cozy. The stretchiness makes movements easy. Will be using it for skiing.

I bought this a month ago as a warm base layer for ski touring and it's exactly what I wanted! Great fit!!!

I bought this due to the excellent wear, warmth, wicking, fit and quality of a RHO Heavyweight Top and Bottom I bought last year. It seems this set of RHO Heavyweight doesn't fill as thick as my previous pair. The RHO bottoms which are large fit tighter and different from my previous large bottoms.

Wore them for the first time today to test them. Was 20 Fahrenheit, sunny day. Wind was about 6 mph. I went for a walk and wore them as my only lower layer. Given the conditions, I found them surprisingly comfortable. Well, my legs were not warm, they were not cold either. I think this was partly due to the sun, given they got a little cooler when I was walking in the shade. Overall, they kept my legs comfortable on the walk. My intention is to use them as a base layer under my ski pants. They fit like pseudo-tights. Not too tight and not too loose. The lining is very comfortable against the skin. I have a 35 inch waist and 32 inch inseam. I chose Large which appears to be the appropriate size.

I bought these a few weeks ago, had them out on a cold day and was super warm. Fit nice and feel even better .

Absolutely fantastic fit, warmth, comfort, flexibility, etc. Good for indoor/outdoor, anywhere, really. One of the best purchases.

The devil is in the details here.... I bought some HH bases at the same time and upon initial review, I figured the HH was every bit as good. But not so, Arc'teryx just does it better. But you pay for that "better". Consider it this way, do you want to wear one or two base layers? These are like two of "the other company's" bases.

I lost my beloved pair of TNF summit series polar tech stretch base layer pants and I thought they were gone forever! This is the exact same product WITH a laminated pocket. I'm 6'3" with long legs (35" inseam) and the insane stretch of these just finds its way down to where it needs to be. They are snug fitting and act as a baselayer, but putting a traditional baselayer underneath would not be impossible. The face of the fabric is smooth and layers well with trekking pants or ski bibs. My only complaint is that the website did not include a fabric gsm. This is included in baselayer descriptions, but never fleece. Most people shopping arcteryx are fabric dorks that need to know these facts to build their layering arsenal. I would guess this piece somewhere around 350 gsm - very warm. Not feasible to wear in above -30 celcius for high intensity activities like running or cross country skiing unless its a stand alone. Phenomenal layer to have in the quiver.
