    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.

    Very comfortable

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

    I love this tank top. It fits really well. I'll wear it hiking or climbing or even go running in it. The bra fits nice. I'm a 32C as well. I bought the green and love the color. I would recommend this product to anyone.

    A New All-Round Favorite

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

    I got this tank as a bit of an afterthought - I was away and needed one and found it at the local store. And although I fully expected it to be fine and not great, boy was I wrong. This tank is so amazingly comfortable and supportive even for high impact sports like running and tennis. It's not tight around the waist and hip areas so it stays down and doesn't ride up when you're in motion. And it has a cute back.

    I've taken to wearing it all the time when it's not in the laundry. As a base layer for outdoor cold weather sports, a lounge-by-pool tank, a go-to-the-farmers-market tank, a running tank, a kickboxing tank, etc.....

    I'm actually contemplating buying at least one more color if not two. I have a bright green color (not sure the name) which is really fun but there are so many others to choose from......

    Highly recommended item.

    A New All-Round Favorite

    Soft and stoked

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    I gave this as a gift to a friend and she was stoked. She said it's very soft fabric with a fit that is loose enough to not feel constricting without being sloppy. It is easy to move in and doesn't ride up like a lot of tank tops have a tendency to do. Perfect for many different activities. The Allum color is beautiful. She can tell I will get a long life and lots of use out of this top!

    Love it

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