SIZE & FIT
Form Fit Slim Regular Relaxed

Relaxed: Our most generous fit that offers relaxed comfort and total freedom of movement without any extra bulk. This fit is free of constraints but still retains shape, structure and clean design.

  • We have changed all of our women's bottoms sizing to numeric to help you find a more customized fit. We had a fit session with models in multiple size ranges, 2/4, 6/8, and 10/12. All models said they could wear either size but it came down to personal preference. Our size 10/12 model said "I would wear the 12 for more layering options and I like a more freeride fit" Our 6/8 model said "I would wear the 6 with a thin baselayer as I would use this primarily for backcountry".
  • Model in Butterscotch and Capers is 5'7" 125 lbs in 6
  • Model in Ruby is 5'7" 140 lbs also in 6

The Siren Bib Features
80/20 Backcountry/Resort
You spend much of your time on a skintrack in search of good snow, and this gear is designed to handle windy summits, spring tours, and long days in the mountains. Fabric choices are made to offer lightweight breathability and air permeability for high-output activities, like bootpacking a couloir. But if there's powder at the ski resort, you'll be there, and this gear can handle all-day liftline laps, too.
