It's all about balance.

When you're zipping through the trees on chilly ski days, snowshoeing to a tucked-away mountain hut, or going on a snowy trail run, the Kari Traa Women's Rett Half-Zip Top provides the perfect balance of breathability and warmth to keep you feeling refreshed and going strong. Made from a technical blend of DriRelease fabric and merino wool, this versatile midweight baselayer insulates efficiently, dries quickly, naturally resists odors, and is wonderfully soft next to skin during your favorite cold-weather activities. Strategically placed panels keep chill-susceptible areas toasty, while longer cuffs with thumbholes lend a bit of glove-friendly coverage.

Best backcountry baselayer

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

LOVE this piece so much. It has dri-release in it, which is super important for me in the backcountry as I sweat a lot more. I never overheat in this or get too cold. It has a brushed fleece on the inside which makes it super comfortable when next-to-skin. I've had a few other Kari Traa baselayers, which are my favorite, but this is the piece I wear the most! Highly recommend.

GO-TO Layer!!!!

This is my absolute favorite top for high-endurance mountain adventures. I use this layer every day splitboarding. The wool wicks moisture while still keeping me warm. It's taken me years to perfect my base layer game and Kari Traa has proven to be the best! I love that this top keeps me warm and still breaths. I tend to get sweating while skinning and cross country skiing - this top wicks it all away and I'm never left feeling wet, cold or smelly after an epic cardio adventure. LADIES - if you skin or XC Ski you have to get this layer - total game changer! I can't wait to use it this spring and fall during my summer hikes and camping adventures!
