For minimal bulk, minimal stink, and core warmth layering, pull on the Arc’teryx EON SLW T-Shirt. The natural odor-resistant property of merino wool means you won’t clear out the lodge when you peel off your coat at the end of a dump day.

  • Merino wool stays warm even when wet so you don’t get chills after sweating or nose-diving into a powder bank
  • Gusseted underarms allow full range of motion whether you’re pole planting or digging for your lost poles
  • Highly resilient stretch maintains skin contact to maximize thermal efficiency and reduce layering bulk
  • Flatlock seams add comfort and minimize chafing so you can go hard during après-ski time as well as ski time

Wow Warm

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

The Eon shirt is the perfect packable addition to any winter trip. When you put it on it is very form fitting but stretchy. Once on you forget about it except it adds an incredible layer of core warmth to any other layering. Also resists odor.

all time fav

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I've had this shirt for about a month now and I can't be happier with the purchase. Wool is so much better than cotton in so many ways. But the best part is that I only have to wash once every week or every other week (on the "short wash" cycle and hang dry). Naturally, wool is more expensive than cotton or polyester but with proper care I will definitely get my money's worth!

Excellent Product

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

I have two of the long sleeved version of this shirt, and was hoping when I got this one that it would be the same fit. Many times, the long and short sleeved versions of shirts can be drastically different. I'm glad to report that if you like the long sleeves, the short sleeve shirt should not disappoint you. For reference, I am 5'10", 165lbs., 42" chest. I knew from the LS versions that medium would be too tight in the armpits, so went with a large. The fit is still snug on my semi-athletic frame, and the arms hug, but don't make me look like I'm trying to win the smedium award. Length is still fine. A tad on the long side, but the snug fit makes it easy to slide up slightly without looking like it's bunched. For outdoors, this shirt is the most comfortable merino product I own, and functions perfectly. For reference, I have shirts from Patagonia, Smartwool, Ibex, and Icebreaker also. None of the others get much use now that I have this in the closet. The other thing I really like about this shirt is that the seams aren't positioned weirdly, and it doesn't have a technical look to it, so I can wear it out and about daily in town. Overall, I give this two thumbs up. One for the mountains, one for the city. I will be getting another one. In fact, as long as I'm here on the page already...

Great base layer

I don't like tight clothing and had to order the XXL so that it didn't feel like a compression shirt. I'm 6'0" 175lbs. It's super light and takes almost no space in your bag or pack. Really good warmth from a fabric this that I'm thinking it will make the perfect sleep shirt while snuggled in the down during a sub-zero winter camp. The shirt has kept it's shape very well after 4 washings. I thinks it's the near perfect base layer for medium active sports.

good review,not enough reviewer's put stats in reviews.
