Icebreaker built its sporty Sprite Racerback Bra from ultralight merino wool with a touch of Lycra for a great fit. The merino wool naturally deals with odor so you won't feel super stinky on the fifth day of your backpacking trip, and the lightweight merino feels soft and smooth against your skin. This fully lined pullover bra has racerback straps that won't slip, and the soft band gives great support without constriction while you run, hike, and play outside.

  • 96% merino wool, 4% Lycra
  • Fully lined
  • Medium support for A/B cups, low support for C/D cups
  • Pullover Racerback with V neckline
  • Foldover elastic at neckline and armhole

Awesome sport bra

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

I'm a 34A and the small is perfect (I'm used to ordering extra small in most products for my petite frame, so I'd say this runs a little small). Doesn't cut anywhere, super soft, no itching, no seam issues. Have had this for a few months now, wearing it for workouts (treadmill/eliptical) as well as out hiking/backpacking. The straps are placed well to be compatible with wearing a backpack without pressure points (that's been somewhat hard to find in a sport bra). The wool is great; doesn't stink like synthetics would by this point. Has held up well, washed on the delicate cycle and line dried. I think for higher impact sports or for larger women this might not offer enough support but it's perfect for me and what I do.

So good next to your skin...

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

True to size, comfortable, ideal for A + cup size. Non-itch wool blend, washes great....dry it on low delicate cycle if you need to...

Smooth and soft

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

I love that I can wear this while carrying a heavy pack and it doesn't rub on my shoulders or back. Its soft and doesn't have any rough or thick seams. Runs true to size and the wool isn't itchy.

Really soft, really comfy. Great to find a sports bra that doesn't feel like plastic! AND after wearing it a few days in a row, like everyone says, it does not smell at all. Merino, you're my favorite.
Also, I'm 34DD and this baby fits! I got the medium. Low impact only, but it's high cut enough that I don't feel like my accidental cleavage is taking over the room. It's wonderful.

Great when you cant wash every day

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

I bought this sports bra to go with the sprite undies for workouts while i was working in Africa and had limited access to a washing machine. I am a 34c and the medium is great. The soft merrino wool resists stink and launders easily.

Stinkless. Period.

I have been a big fan of wool baselayers for years. But, until recently, never thought I'd wear wool underwear. After a long ride in the mountains where my baselayer kept me warm, but my synthetic bra left my boobs chilled, I ordered the Icebreaker Sprite Bra. What can I say? I LOVE it. I actually wore it 3 days in a row after being injured (right after I bought it -- couldn't move shoulder to remove it) and I am very happy to say, that it did not smell at all. I'm sold on wool sports bras and am ordering all the colors!
