Look good, smell good, and stay good and warm.

Whether you're ice fishing for a week or entering a team in the Iditarod, you won't be doing laundry for a while. The Arc'teryx Men's Long-Sleeve Rho LTW Zip-Neck Top was designed with you in mind. Made from New Zealand Merino wool, this top naturally regulates your temperature and minimizes bacterial growth so the shirt won't stink like a football locker room after a day on the trail. The touch of elastane lets the shirt bounce back, day in and day out, for extended wear.

Gusseted underams gives you freedom of movement to reel in a record-breaking northern pike. Open the neck zipper when you need a little air to cool down. Even if week-long winter camping isn't your idea of fun, the longer length lets you tuck it in without sporting tails. The next-to-skin fit lets you sport a trim profile; complete the look with jeans and driving loafers.

  • Naturally antimicrobial, naturally regulates temperature
  • Gusseted underarms
  • Half-length neck zipper
  • 1 laminated chest pocket, zipped

Solid Base Layer

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Height: 6' 1"
    Weight: 190 lbs
    Size Purchased: Large

I purchased two of of these a few years back and I wear them all the time in the colder months. The fit is small, so size up. After reading the reviews I went for a large when I would typically buy a medium. I give it four stars for the fit which is a comfortable snug - a bit clingy without making me feel like I am wrapped in a sausage casing. I find the merino to be reasonably soft considering is is wool. If you are sensitive to a slight wooly feeling it might not be for you. It wicks moisture like a shop vac. I peel it off after intense cold weather activities and cannot believe how much it holds. That said it does end up carrying a bit of weight depending on the activity, but I find it is not something I do not notice until I am taking it off. Overall, a damn good piece.

Very tight fit

  • Gender: Male
  • Familiarity: I returned this product before using it
  • Fit: Runs small

I have tons of ArcTeryx stuff, way more than I should, and pretty much always wear medium. Small in a few cases, never large. This one is a really tight fit in medium. Not in a flattering way (granted that's more on me). To be fair, ArcTeryx tells you that it's a tight fit and I don't know how much it stretches over time, but it really is formfitting.

Perfect Base Layer

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

Love this piece. Have been looking for a good base layer for skiing and hiking and this takes the cake. Incredibly comfortable and very functional. The chest pocket is super convenient should you need to stash ID, a credit card, or a few bucks in it and, maybe my favorite part of the shirt, is the tapered bottom. I always had the problem of my base layer riding up my back but with the longer tail on this shirt, it never happens.

The shirt is a little tighter fitting that I had expected. I'm 5'11", 170 lbs and usually wear a Medium in Arc'teryx. Had to exchange for a Large here and it fits great. Huge fan and would highly recommend to others.

Great base layer.

  • Gender: Male
  • Familiarity: I've used it several times
  • Fit: True to size

This layer is as functional as it is good looking. I feel that this layer is absolutely essential for going into the back country or everyday winter outings. Gotta have the wool.
