Fabric

Made from ultra-soft 18.5-micron Merino wool, this 150gsm fabric provides lightweight yet effective warmth. Certified to the Responsible Wool Standard, this Merino wool ensures ethical sourcing and responsible land management, supporting biodiversity and humane animal welfare practices.

  • 87% Responsible Wool Standard Merino Wool

  • 13% Recycled Nylon

Merino wool is a natural performance powerhouse, offering breathability, moisture management, and odor resistance. To enhance durability without compromising softness, we’ve blended in 13% recycled nylon, making these leggings stronger while maintaining the luxurious feel and no-compromise-performance of Merino wool.

Fit

The Katabatic Base Layer Bottoms offer a form-fitting, legging-like silhouette with a higher-rise waistband that sits at the belly button for most wearers.

Choose from two fit options:

  • Wild Iris Fit – Ideal for those with a straighter body shape through the upper and lower hip.

  • Azalea Fit – Designed for curvier figures, with a narrower waist and more room in the hips.

Need help deciding? We recommend starting with the Azalea Fit in bottoms, based on customer favorites.

Alpine Fit

Review Summary:

Customers praise Alpine Fit for soft, thoughtfully constructed outdoor apparel that stays comfortable through hiking, travel, layering, and everyday wear.

Reviewers often highlight secure pockets, odor-resistant fabrics, smooth seams, and fit options that accommodate different waist-to-hip proportions more effectively than standard sizing.

Fit still varies by style and fabric. Shoppers should compare body measurements and choose carefully between the brand’s straighter Granite fit and more tapered Cinder fit, particularly for leggings and base layers.

Highlights & Considerations:

  • Soft, durable technical fabrics
  • Secure pockets and thoughtful construction
  • Choose the correct fit profile and size
