Frequently Asked Questions

• How does the Women's Environ Jacket compare to the Women's Environ XT Anorak for alpine touring and resort use?

  The Environ Jacket is a full-zip shell built for on/off convenience and layering, while the Environ XT Anorak uses an anorak-style pullover cut that offers extended coverage and simplified weather sealing. The anorak favors deep-powder days and minimalist layering, whereas the full-zip Environ is more versatile for quick transitions, ventilation access, and pack or harness use.
• How does the Men's Azura Insulated Hooded Jacket compare to the Men's Objective Pro Jacket?

  The Azura Insulated Hooded Jacket pairs synthetic insulation with a waterproof shell for colder, lower-output days when built-in warmth reduces layering needs. The Objective Pro Jacket is a performance-focused 3-layer hardshell (using technologies like GORE-TEX 3L Pro or similar PeakProof™ constructions) prioritizing waterproofing, breathability, and durability for sustained skinning, bootpacks, and wet, variable conditions. Choose Azura for cold resort laps and chill descents, and the Objective Pro for high-output backcountry missions.
• What waterproofing and breathability technologies do Stio ski jackets use, and how do they perform during aerobic backcountry missions?

  Stio employs membranes such as PeakProof™ 3-layer, GORE-TEX 3L Pro, and Dermizax with fully taped seams and DWR finishes, commonly rated around 20,000 mm waterproofing and breathability figures of 10,000 g/m²/24hrs or higher. Those specs plus pit zips and venting manage heavy wet snow and promote vapor escape during long skin tracks, though active layering and using pit zips are recommended on very high-output days.
• How should I size a Stio ski jacket to ensure room for layering and freedom of movement?

  Stio generally offers a relaxed, freeride fit designed to accommodate a midlayer and allow unrestricted movement; consult Stio’s sizing chart for torso length and sleeve mobility to match your build. If you plan to wear a thick puffy underneath keep your normal size for layering room; if you prefer a streamlined, technical fit with minimal bulk, try one size down and test mobility with the layers you intend to use.
• What features should I prioritize when choosing a Stio jacket for backcountry versus resort skiing?

  For backcountry use prioritize a true 3-layer waterproof membrane (PeakProof™/GORE-TEX 3L Pro), high breathability, large pit zips, harness- and pack-friendly pocket layouts, and a helmet-compatible hood for mixed touring and descents. For resort or freeride focus on insulated options (like the Azura), integrated powder skirts, longer cut for coverage, and extra storage for goggles and accessories.
