Show Description

Weather protection for all four seasons. These bibs use an incredibly durable shell fabric with mechanical 2-way stretch, so you are free to carve, kick turn or high step without restrictions. The Atmos™ membrane is hydrophilic, not micro-porous, meaning breathability won't be compromised when the jacket gets dirty. Harness-compatible pockets, 3/4-length vents and reinforced kick patches round out this backcountry staple.

  • Durable Loop Hardshell™ ripstop polyester has 70% recycled content.
  • Atmos™ waterproof-breathable membrane repels moisture.
  • Fully taped seams and fluorocarbon-free DWR finish keep wetness from seeping in.
  • 3/4-length zippered vents let you release heat when you're working hard.
  • Waterproof zippers.
  • Thigh pockets positioned to allow access when wearing a harness.
  • Integrated gaiters layer securely over boots.
  • Schoeller reinforced kickpatches protect against sharp edges.
  • Should this garment wear out after years of use, it can be returned to Houdini for recycling.

Fabric waterproof rating

The standard test for waterproof fabrics uses a standing column filled with water. The figures given are the water column height. A rating of 3,500mm or higher can be considered waterproof. The higher the rating, the more durable the waterproof fabric will be over time.


Waterproof garments use waterproof-breathable technologies and are fully seam-taped. Water-resistant garments use waterproof-breathable technologies but their seams are not taped. Water-resistant garments repel water and protect against wind but are not made of waterproof fabric.

Waterproof with fully taped seams
Fabric active breathability

The rate at which a waterproof breathable fabric expels moisture when the inner surface is moist from perspiration. Values under 8,000g/m2/24h provide low performance, 20,000g/m2/24h provide moderate performance and values over 30,000g/m2/24h provide high performance.

Venting ¾-length leg zips with storm flap
  • 2 side zippered
  • 1 internal zippered

A windproof garment does not allow any air to permeate the fabric. A garment with windproof panels has panels of fabric that are totally windproof, but the rest of the garment may not be windproof. A wind-resistant garment resists some wind, but not as much as a garment that is windproof.

Durable water repellency

Usually referred to as DWR. A treatment made to fabrics that causes water to bead and run off instead of soaking through.
