It's hard to resist the Icebreaker Women's Siren Long-Sleeve Crew. Made with luxuriously comfortable merino wool fabric, the Siren offers a body-hugging fit ideal for layering beneath your sweater or hoody, and it looks stellar when worn alone with your capris or hiking pants.

  • Icebreaker's lightest weight merino wool regulates your body temperature, dries quickly, and feels smooth against your skin
  • Merino wool also naturally deals with odor so this top doesn't get stinky on long treks, hut trips, or vacations
  • Body-hugging fit makes it ideal for layering beneath a flannel, hoody, or blazer
  • Soft fabric binding and set-in sleeves offer comfort

Because Backcountry.com ships super fast it is probably already on the way- if it is too small they will take it back no questions asked and you can just re-order another size. Next time if you chat with a gear head right after you place the order they can sometimes stop the order for you- FYI.

With IB I tend to order up (1) size (on shirts, tanks, pants & sometimes on undies) ...as a lot of their cuts are narrow & form fitting. It really depends on how tight/form fitting you want it ...I prefer the x-tra room. Also, during cooler temps it allows me to layer by wearing a thinner weight 150/200g/m Tank, SS, LS Top under my 260g/m shirt...same goes for addt'l legging coverage (if needed).
