How does Gore-Tex work?
Membrane Layer
GORE-TEX is a proprietary technology for top of the line technical outerwear. Each square inch of GORE-TEX membrane contains up to 9 billion pores, each pore is 20,000x smaller than a water droplet, and 700 x larger than a water vapour molecule.
What do these numbers mean? It means the GORE-TEX membrane is the most waterproof, windproof & breathable fabric out there. You want your outerwear to be breathable to allow sweat to escape, otherwise it will build up in the garment and make you wet & cold.
Outer Shell Layer
The outer layer is either a soft shell or a hard shell, the middle layer is the GORE-TEX membrane and the inner layer is a wicking fabric that draws moisture vapor from the body.
The outer layer is often treated with a DWR coating to help water bead off and not build up on the garment. (Although the water won’t penetrate through the GORE-TEX it can still make you feel clammy.) GORE-TEX rigorously tests all products that have their name on it, and they provide a guarantee of keeping you dry.
GORE-TEX Guaruntee
If the garment fails, you can send it to GORE-TEX with proof of purchase and they will repair, replace or refund you. At UNLTD GORE-TEX can be found in men's & women's outerwear as well as some mitts & gloves.
Before jumping the gun and thinking your gear is "broken" we recommend giving it a wash and DRY. This can rejuvenate the DWR coating, allowing water droplets to bead off effectively once again. You can find more info on caring for your Gore-Tex outerwear below.
GORE-TEX VS. GORE-TEX PRO
GORE-TEX 2L & 3L
The original GORE-TEX breathable, waterproof & windproof membrane is more affordable than it's PRO counterpart & is geared towards everyday use. Original GORE-TEX garments utilize a Polyurethane backing & can be found in 2 or 3 layer options. 2L garments have 2 distinct layers, the outer shell & a soft inner layer, they can be found with or without insulation.
GORE-TEX 3L is 3 layers of fabric/membrane, but they are bonded together to make a single layer, unlined, uninsulated, high performance shell. 3L is lighter weight and more breathable. Since original GORE-TEX can be utilized in a wider range of fabrications, it's more common than PRO.
GORE-TEX PRO 3L
GORE-TEX PRO is a lighter, more technical, more rugged, breathable fabric. The garments that use GORE PRO are prepared for the most extreme conditions, with a Micro-Grid backer which is more durable than Polyurethane & a rugged outer layer. It's lighter than the original membrane & can be fabricated to offer much more stretch. GORE-PRO is only used in 3L construction, so you'll only find it on shells with a bonded abrasion resistant/GORE-PRO/Micro-Grid single layer.
This advanced tech is more expensive and truly isn't necessary for everyone.
GORE-TEX FAQ'S
Will GORE-TEX keep me warmer?
While it does provide protection against wind & water which will help keep you warm, GORE-TEX on its own has no insulating properties. Many GORE-TEX products are a 2 or 3 layer waterproof/breathable fabric without insulation and are considered shell jackets. These were designed like this so you can layer underneath with either a technical fleece or a down/synthetic puffy depending on the warmth you need for that day’s conditions. Some jackets have a GORE-TEX layer and are lined with a down or synthetic insulation layer to add warmth.
Why is GORE-TEX so expensive?
GORE-TEX has come a long way over the years, the proprietary tech lends itself to about 100 brands and there are several options for GORE-TEX thickness. Because of this, the price point of GORE-TEX in outerwear has come down quite a bit since it was invented. We have GORE-TEX jackets at the shop starting around $300. Although this price point may be higher than other shells/ jackets, the tech available in GORE-TEX is unparalleled in both performance and durability. In the long run, you may appreciate the advantages & longevity of a GORE jacket versus another option you’d have to replace sooner.
My jacket gets waterlogged, does GORE-TEX stop working?
It’s not the GORE-TEX that’s stopped working, it’s the DWR coating. Non-Gore options rely heavily on a DWR coating which forces water to bead off the garment. GORE-TEX fabrics utilize the same DWR coating which works hand in hand with the GORE-TEX membrane for superior water repelling. Heavy use of any garment coated with DWR will eventually need to be refreshed. It may seem counterintuitive to machine wash & dry your GORE-TEX outerwear to revive the DWR coating, but it’s not! The coating actually relies on the heat of the dryer to realign the microscopic pegs that repel water. Keep reading for GORE-TEX care instructions. If washing & drying fails to reinvigorate the coating, you can use a spray or wash-in product to achieve a like new water repelling result.
Are there alternatives to Gore-Tex?
Since Gore-Tex is a proprietary technology, some brands opt to put the research & development into their own fabrics. FUTURELIGHT is The North Faces' ultra-thin, nimble fabric that feels comfortable and provides the protection needed against the elements in the harshest environments. Designed for rugged mountain enthusiasts, FUTURELIGHT outerwear will keep you dry and comfortable just like Gore-Tex.
Pertex serves a similar function, growing in popularity with outerwear brands as a long lasting, more eco-responsible alternative to Gore-Tex.
