Are waterproof Jackets, why the average Jackets are so cheap, and labeled Gore-tex or other waterproof materials such as eVent, HyVent Jackets is simply more expensive than the average Jackets? Although the brand promotion and licensing fees accounted for a large part of the selling price, its fundamental differences in waterproof fabric material, air permeability, and detail design all affect the price of the entire waterproof jacket.
Waterproof jacket material, air permeability, design details are reflected in the price
The price of waterproof jackets mainly depends on the following points:
1. Waterproof:
Generally we call waterproof jackets, the standard of which is that “water pressure resistance up to 10,000mm†can meet the definition of waterproof. The greater the value, the better the waterproof capacity. What is the water pressure of 10,000mm? It is probably a high-pressure water column used for firefighting, or a pressure that is hit by a waterfall. Therefore, basically, as long as it has a water pressure resistance of 10,000 mm, it is generally sufficient for outdoor use.
2. Moisture permeability:
Waterproof coats are not difficult to waterproof, but it is not easy to be waterproof and breathable. Normal raincoats are completely waterproof, but we know these raincoats are hot and completely airtight, if only Riding a bike or walking can be tolerated, but when engaged in active climbing activities, the sultry, airtight raincoat will quickly cause a damp-proof effect, gradually turning into a double-wet raincoat, not only wet outside, but also inside. It is wet because of the dampness.
The moisture-permeable (gas) nature of the waterproof jacket greatly affects the comfort during travel
In general, the waterproof, breathable/breathable layer in the market can be roughly divided into:
Non-porous membrane
The common material is PU polyurethane (Polyurethane), TNF waterproof cloth - HyVent is this one, belongs to the indirect breathable (wet breathable) material, because this kind of fabric makes use of the hydrophilic property of the film to allow the inner layer to absorb moisture and become the water molecule. , Let the water molecule gas be discharged outside the raincoat due to the difference in internal and external pressure. This way we call it moisture permeability (indirect air permeability). Usually the air permeability is not good, but the price will be cheaper.
Porous membrane
The common material is ePTFE film, which is the eVent because it allows the gas to pass directly through the pores of the microporous hydrophobic membrane. Due to its high speed, it is a direct gas-permeable material, and usually has the best air permeability and the price is expensive.
Non-porous hydrophilic membrane + porous membrane
This is the method we are familiar with using Gore-tex, but why do we add a PU layer to ePTFE? Mainly to resist oil pollution, because the oil easily plug holes, and affect the ventilation effect, but also because the addition of PU layer, usually lead to less breathable than event material, the price is expensive. However, PU coating also has a very important function, which can improve the durability of waterproof jacket.
* Nonporous, airtight materials are not recommended for mountaineering activities.
3. Table cloth water repellency:
A good waterproof jacket, the surface fabric has excellent water repellent ability, often referred to as "Durable Water Repllen (DWR)", if there is no excellent water repellent ability, the surface of the waterproof jacket will be wet due to rain Gradually absorbing water, the surface fabric after absorbing water will affect the breathability of the waterproof jacket, and finally it will be as easy as the general raincoat. The more durable the jacket is, the better the water repellency is, the higher the price is usually.
However, durable durable water-repellent treated cloths will gradually lose their water repellency after repeated use and washing. At this time, professional water repellent can be used for maintenance, and the table cloth can be resilience-proof.
If the jacket has excellent water repellency, the table cloth will not absorb water due to rain
4. Combination of table cloth and waterproof film:
There are generally two methods of laminating a surface cloth and a waterproof film, such as “lamination†and “coatingâ€. The lamination can be combined with the surface cloth in the manner of wallpaper, and is usually more durable. The price will be more expensive; the coating can be imagined as a combination of brush painting and table cloth, and the service life is usually less durable. The waterproof film will peel off in about 3 years, but the price is relatively cheap.
Adhesives Advantages Disadvantages Deterioration Aging Condition Coating Cheap Durability Years Lower Powder Peeling Fitting Expensive Durable Life High Flake Separation5. Multi-layer structure:
Once the waterproof film peels off, it means that the life of the waterproof jacket has come to an end. Therefore, there are several ways in design to isolate the direct contact between the film and the body and sweat to increase the service life of the waterproof film.
Table cloth + film
That is, 2L two-layer cloth, some 2L cloth will be designed with separate mesh lining, mainly to isolate the film and the human body contact, usually the best air permeability.
Table cloth + film + fit inner cloth
It is a 3L three-layer cloth. This lining cloth is different from the separate meshes, but it is closely combined with the surface cloth and the film. It is usually the worst air permeability, but it is more durable.
Table cloth + film + Coating protective layer
That is 2.5L two half cloth, usually air permeability and durability are at the intermediate level.
6. Detail design:
Underarm zipper
Although we can see how good the breathability of many technologies is, it is definitely not as good as a waterproof jacket with an underarm zipper design. However, the design of the underarm zipper may cause some people to use the zipper. Points also need to be considered.
Reduce stitches
Wherever there is a seam in the waterproof jacket, a waterproof strip is usually required to prevent the thread from seepage. However, the strip may be worn out after a long time, so the waterproof jacket with less seams can reduce the chance of seepage.
Table cloth wear
Waterproof jacket is the outer layer of our three-layered wear method. If you carry a backpack, you may be easily worn out near the shoulders due to the pressure of the backpack straps. Therefore, some waterproof jackets will be thicker and more resistant to this part of the fabric. The table cloth, as for other parts, is still using a light and thin cloth, or the whole piece is a thicker, more wear-resistant table cloth. Like FuseForm weaving technology, different fabrics can be woven into a single fabric structure, so that different fabric characteristics are expressed on the same fabric. This innovative approach can not only greatly reduce the suture section, but also can effectively reduce the overall waterproof jacket the weight of.
As the waterproof jacket is the first line of weather, it must be carefully selected, but its choice should be relatively simple - waterproof, moisture permeability (gas), surface water repellency, surface cloth and waterproof film The combination of methods, multi-layer structure, plus the above details design, etc., these will affect the price of waterproof jackets, depending on the user's needs.
