Don't just 'go' the distance, surpass it.

When your performance actually matters, ditch the cotton tee and upgrade to the Arc'teryx Women's Senna Tank Top. Your torso deserves better than moisture-retaining cotton. This strappy tank offers an outer later composed of the awesome Haven material, a single-knit polyester jersey fabric with spandex for supreme mobility on that precarious rock face or nigh-vertical trail. Inside, the Senna includes a convenient built-in shelf bra with insert pockets for adjustable support and comfort. Composing the shelf bra is Aerial polyester, a lightweight mesh lining with moisture-wicking superpowers. Arc'teryx has treated the Aerial mesh with a Polygiene finish to battle the forces of odor with miniature viking warriors. The Senna sports a full-coverage length to take advantage of its UPF 50+ rating, high quality sun protection.

  • Haven polyester/spandex blend
  • Aerial mesh shelf bra with insert pockets
  • Anti-odor Polygiene
  • Moisture-wicking stretch
  • Athletic fit
  • 50+ UPF sun protection

Here's what others have to say...


Love it

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:True to size
  • Height: 5'2"
    Size Purchased: medium

I will reiterate what Charissa said below. It's not tight/restricting and you don't have to keep adjusting it. The straps are perfect length for me too. It is true to size for me.


Love it

    this is a great running tank! For me it fits true to size. I weight 125-130 and 5'6" and the small is perfect. What I love about the material is its not restricting and super tight, it lets you move and you don't have to be readjusting it while running. The straps are not long and are the perfect length so you feel comfortable in it. I also love that it has the option for you to put pads in it, if you so desire. Great running tank!


    Great Tank, Large-ish Fit

    • Familiarity:I've used it once or twice and have initial impressions
    • Fit:Runs large
    • Height: 5'3"
      Weight: 114 lbs
      Size Purchased: small

    I'm 5'3, 112-115 lbs, with a 32C bust, 25.5-inch waist and 35.5-inch hips. I'm almost always a small in Arcteryx, so it was a surprise to me when this small, trim-fit tank was blousy enough to tuck in and fluff up a bit. Even with the wonky sizing, the shelf bra is snug enough for support while hiking (although not jumping), but I'll dry it in the dryer in hopes of slight shrinkage. It's also OK that my tank is a little blousy, since my hiking pants all seem to have drawstring waists and don't play nicely with fitted tanks.
