A freeride‑ready women’s hardshell that trades PFAS for GORE‑TEX ePE without giving up storm protection. It’s the one I reach for on cold, windy lift days and hike‑to laps; light enough for short tours with an Aenergy IN mid.

Why Eiger Free vs. Nordwand

Eiger Free Advanced HS (women)—black hardshell with orange liner, front view.

Eiger Nordwand HS in blue—PFAS-free GORE-TEX ePE.

  • Eiger Free Advanced HS: slightly softer, friendlier for resort + sidecountry; value vs. Pro‑level shells.

  • Eiger Nordwand HS (Advanced/Pro): stiffer, burlier alpine cut, best for sustained above‑treeline exposure.

Fabric & weatherproofing

  • Membrane: PFAS‑free GORE‑TEX ePE (waterproof/breathable), fully seam‑taped.

  • Details: helmet‑compatible hood, pit zips, snow‑skirt, cuff/hem adjustments, pass pocket.

Fit & sizing

Regular freeride cut with room for a warm midlayer. True to size; if you run heavy midlayers, consider sizing up. Try it on with the Aenergy IN to be sure.

Recommended use

  • Resort, cold & windy: shell + Aenergy IN + thin wool base; use Stoney HS Thermo only for deep‑cold snaps.

  • Storm day/freeride: Eiger Free HS + Aenergy IN + breathable bibs; add balaclava and beefier gloves.

  • Short tours: pairs well with a light pack; vent early and often.

Pros/cons

Pros
• PFAS‑free waterproofing (GORE‑TEX ePE)
• Storm‑proof hood and zips
• Resort‑friendly features (skirt, pass pocket)
• Lighter feel than alpine‑first shells

Cons
• Not as armor‑like as Nordwand Pro
• Pricey—watch for sales
• Color availability rotates by season

Good pairings

  • Midlayer: Aenergy IN Hooded — Women

  • Pants: Mammut freeride bibs or Stoney Thermo Pants

  • Safety: Barryvox 2 — Overview & Buyer’s Note

Should you buy it?

  • Best for: resort and sidecountry skiers who want PFAS‑free storm protection in a freeride cut.

  • Not for: daily above‑treeline or expedition use—consider Eiger Nordwand Pro instead.
