Pursue dream lines in uncompromising comfort.

Skiing thousands of vertical feet requires an awful lot out of your base layer. Namely, heat-trapping warmth at bone-shivering altitudes and moisture-wicking comfort during fast descents. Fulfilling these demanding requirements, the Arc'teryx Men's Rho LT Bottom keeps you pleasantly warm and dry, regardless if you're ripping morning groomers at mach 10 or arcing heavenly turns in pillowy powder.

Torrent fabric offers the best attributes of lightweight warmth, quick-drying comfort, and full flexibility for cold-weather activity. The bottom's next-to-skin fit slides effortlessly under outerwear and articulated patterning ensures full range of motion for getting after the lines of your dreams. As a fresh-wearing bonus, the Polygiene treatment fends off funky odors after a full day of skiing.

Base Layers of all Base Layers

  • Familiarity: I've used it several times

Soft, feels great, super comfy, I still am confused for the little pocket that it comes with but I am sure that the one day I need it I'll forget that its there. All in all sweet base!

Only Base You'll Need

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Large
  • Height: 6'1"
  • Weight: 195lbs

Perfect base layer, fits very well and doesn't stretch out but also not tight. Fabric is very soft and so comfortable. Does not absorb smell and wicks moisture very well.

    Great bottom base layer

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'0"
    • Weight: 175lbs

    I have owned a few of the Rho LTW tops over the years, and have worn other brand bottoms. Finally needed a new set so I decided on these. Comfortable, super warm and a great fit. I expect to use these for biking, skiing and backpacking for the next several years.


      This is the perfect base layer for me. I'm 6'3 240 and the XL fit nicely. They are roomy, but not baggy. These things DO NOT stink - I can't smell a trace of gnarlyness after many (10+) days on the hill and no wash.

      Comfortable, warm, moisture wicking, smell resistant - well worth the price.

      Does the job

        Have worn these skiing and backpacking. The material is very soft with a good amount of stretch. I am wearing a a large and I am 6' 3" and weigh about 180. I am slightly concerned about them wearing out. The material doesn't seem incredibly durable. Overall they are warm and do the job. Arc Teryx loves to put those little pockets on everything, but I've yet to actually use one.

        Prefer AR's for layering

          This is a nice fabric but I generally prefer the powerstretch AR bottoms in my layering setup. These are nice weight though if you're hiking for turns or if it's a little more spring-like

          Ultimate baselayer

            ...and for the price, they should be! These are very nicely constructed (could do without the laminated pocket - not sure what their obsession is with these things, but, whatever). Extremely comfortable, seem to be very odor-resistant, moderate warmth. Intended to be form fitting, so don't size up.
