Arc'teryxA2B Tank Top - Women's

For the urban hustle.

For those of us confined to the daily grind of urban areas, life isn't always idyllic hikes through forest preserves and technical ascents up alpine faces. Fortunately, the Arc'teryx Women's A2B Tank Top is smartly equipped for urban life with its fashionable racerback silhouette and cool-wearing fabric.

Polylain fabric crafted from polyester and merino wool aides in temperature regulation by pulling perspiration off your body for rapid evaporation. This means you'll commute comfortably without soaking in sweat on those sticky summer days. Another benefit of this fabric is that merino wool fibers naturally prevent odor build-up for lasting freshness.

  • Cool-wearing comfort for urban commutes
  • Trim fit with ample length for layering
  • Racerback silhouette keeps you cool in summer
  • Polylain fabric dries quickly in hot weather
  • Merino wool fibers naturally prevent odor build-up

comfortable high quality tank top

A2B Tank

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: XS

I purchased this for rock climbing and hiking. I have used it a few times, and the material is light-weight and stays dry and cool. I purchased it in scarlet, and it was true to color in person.

Regarding the fit: I am 5'10, 130 lbs, 32B, and a size XS fits perfectly (this is the size I normally purchase in Arc'teryx tops). It's form fitting, but not overly tight. I like that the top is a bit longer and goes over my hips. My only complaint is that the top is a bit too high under the armpits.

So soft!

I got this as a gift for my girlfriend, but she absolutely loves it! Super soft, and a great fit.

Arc'teryx does it again

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

I've been so so thrilled with this piece, which I bought mainly to use as a base layer while hiking.

I'm pretty truly a medium in most things, but occasionally a large with Arc'teryx. I checked out both for size, and went with the medium, as the length suited me best. I'm average-ish height and have an average-to-short torso (18" pack size), and the medium hits me just at the hip.

The fabric has been incredibly comfortable, light but not see-though. I've used it so far running, hiking, and for travel, and it's held its shape (and smell...) exceptionally well. Overall, very thrilled with this piece, which has performed well even with the "everyday" label from Arc'teryx.


  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: Medium

I really wasn't wild about the fit of this tank--it's made with nice, silky/breathable fabric, but "trim and long enough for layering" isn't quite how I'd describe it.

I'm 5'9", 135ish lbs, 28in waist, 35in hips, with a 34B chest, and the medium was loose in the top half/shoulders, and SNUG from my belly button to hips. The tank just squeezed all the wrong places, and tended to ride up during climbing movement. Size down if you'd like a form-fitting tank, but size up if you're looking for a layering tank.
