Description

Our new women’s flannel overshirt is designed for mountain life. This isn’t your classic wool flannel that feels scratchy – this one is incredibly soft against your skin, made of an innovative blend of recycled Merino wool, Tencel and Modal. It features a soft, layer-friendly fit, and it’s sustainable down to the details with biodegradable fibers and biomass buttons. The Treeline Flannel is luxuriously cozy, odor resistant and breathable. It’s the super soft, versatile flannel we’ve always wanted.

"A blend of recycled Merino wool, Tencel and Modal fabrics combines with Japanese-made biodegradable buttons and handy chest pockets for a cozy, functional garment you can basically rock year-round." - Gear Patrol

Product Features
  • Super soft combination of recycled Merino wool, Tencel and sustainably harvested Modal
  • 100% natural & biodegradable fabric
  • Designed with soft fabric to layer over a tee or tank for year-round wear
  • Japanese-made biodegradable buttons created from biomass
  • Chest pockets with flaps
  • Twill tape and chevron stitch detail at interior collar
  • Contrast-color lining
Fabric Details
  • 36% Tencel Lyocell, 32% recycled Merino wool, 32% Modal
  • 275 GSM fabric weight

About TENCEL™ Lyocell and Modal

Keeping in line with our commitment to incorporate natural, sustainable fabric and practices, Tencel and Modal are perfect additions to the Ridge product line. Both offer a great complement to Merino wool’s natural temperature regulation and technical performance, and they’re incredibly soft.

These fibers are sustainably produced from renewable wood pulp (Tencel from eucalyptus trees & Modal from beech trees) and are certified compostable and biodegradable, meaning they can fully revert back to nature.

Care: Machine wash on warm or cold, hang dry, do not bleach or dry clean, iron on low wool setting. Learn more.

Sizing/Fit
  • An easy fit for layering that isn’t too slim or too baggy
