It wasn't very straightforward when Gore rebranded WS as Infinium and had the film out stuff included under that umbrella. They might have started with FO labeled as Infinium and then expanded to include WS idr exactly. Yeah all the PB and FO products are considered to be "Infinium tech" even though you get persistent beading whereas WS isn't WP. Whatever the the face is laminated to gives it a different feel/look as well (ex: J62/63-PB, J63A-FO vs. J46-FO, J67-FO).
Gore-Tex® Film Out Hooded Jacket
Type WR Gen. 1 Style Softshell
The future is fluid. J63 is the first ever hoody built in a completely new type of GORE-TEX® laminate. It shifts focus from the external to the internal, from toughness to softness, from resistance to well being. A new proprietary technology forms a component fabric with persistent beading and extremely low water pick up. This means no bulky face fabric is needed. The result is comfort and quiet unlike anything before it. Suitable for an incredibly wide spectrum of interior and exterior climates; it is the closest thing to a second skin we have ever experienced.
The laminated face of the fabric will 'break-in' and develop it's own individual shine and patina with time. Durability and appearance will vary with type and style of use.
The jacket itself carries the promise of the fabric to it's logical conclusion. A marriage of the timeless simplicity of a hoody with the sophistication of true minimalist design. Fit is zero resistance and grafts to the body with anatomic sleeve anchor loops. Internal security pockets are zippered and in holster position for optimal weight distribution. Exterior pockets are deceptively voluminous with pocket bags extending to both the front and back of the garment. Sleeves are lined for the smoothest possible layering. The new 2-way overlap zip hood can be adjusted to any height for any amount of coverage. And although J63 is so light you'll likely to forget you're wearing it, should you need to doff, the signature Acronym Jacketsling keeps it handsfree.
