Technology
GORE-TEX
GORE-TEX guarantees you will stay dry and warm in any condition, for the life of your garment.
Thermagraph®
Thermagraph® technology is strategic body-mapped insulation and breathability to increase the versatility of your outerwear.
Taped Seams
The seam taping process prevents moisture intrusion by making the seams as waterproof as their surrounding fabric.
Hoodlink
The jacket is folded, rolled, and then the hood bungy tightens around the bundle to keep it that way.
PFAS Free DWR
C0 PFAS Free DWR (Durable Water Repellency) coating is the outermost finish applied to 686 fabrics for protection and waterproofing.
