Women's Apex Parka
Between sizes? Size up if layering heavily for cold-weather expeditions. Size down for a streamlined shell fit over a base layer.
Product Details
Enhanced Design. Elevated Function.
The Orion Apex introduces a redesigned fit and improved articulation for unrestricted movement in any condition. Streamlined style lines and reshaped pocket access create a cleaner look and more intuitive use. A deeper hood with an updated front brim provides greater coverage and visibility, while a magnetic hem closure delivers a crisp finish that functions seamlessly in motion.
Engineered for Harsh Conditions.
Fully insulated with SOLARCORE®, the same NASA-inspired aerogel technology trusted for extreme environments, the Apex features enhanced insulation mapping for better warmth and ventilation balance. Its waterproof construction—fully seam-sealed with a bonded storm flap—shields you from rain, snow, and wind without added bulk.
Every Detail Refined.
A new VISLON front zipper ensures smoother operation, paired with refined placket snaps for quicker release. The adjusted back hem eliminates peaking, maintaining a streamlined profile in motion. Inside, comfort cuffs and a draft collar at the back neck and waist keep cold air out, while an interior zip pocket secures your essentials alongside four exterior zippered pockets for easy access.

SOLARCORE® Insulation
NASA-derived warmth without the bulk
Expert Support
Specialists, when you need them
About Our Technology
Enhanced Design. Elevated Function.
Deeper Hood
The Apex hood has been cut deeper for more coverage, with a reshaped front brim that keeps rain and snow off your face. You still get a clear line of sight. Insulation and a drawcord let you fit it snugly when the wind picks up.
Aerogel Insulation
SOLARCORE® aerogel insulation is based on technology developed for NASA, so the Apex stays warm without bulky layers of fill. Insulation mapping puts warmth where your body loses heat fastest and lets the coat breathe where you run hot.
Storm-Sealed Front
A two-way VISLON® zipper sits behind a bonded storm flap to block wind and water at the most exposed seam. Every seam is fully sealed, and refined placket snaps make it quicker to open up when you head indoors.
Secure Storage
Four exterior zippered pockets have been reshaped so they’re easier to reach while you’re moving. An interior zip pocket keeps your phone, keys, and wallet secure and out of the weather.
For Your Morning Commute
From frozen trailheads to the walk to work, the same insulation keeps you moving without the bulk. Layer it, pack it, live in it.
For Your Weekend Adventure
From frozen trailheads to the slopes, the same insulation keeps you moving without the bulk. Layer it, pack it, live in it.
