关于冬季钓鱼防水服装的选择

Spending time with Mother Nature is a wonderful thing. But a spring squall, freezing snow, heavy humidity or even an unexpected puddle can turn you into a soggy excuse for an outdoor adventurer.
Gone are the days of sweating and sweltering under rubber rain gear. Your grandpa's stifling yellow slicker has given way to sophisticated outerwear that delivers waterproof breathable protection in all wet conditions. Many of the new microfiber fabrics and laminates allow for a generous air flow, have wind-breaking properties and still shed moisture in a softer, lighter and less bulky package than traditional waterproof gear.
No matter the activity or the weather conditions, Sierra Trading Post has the right gear to keep you dry - and this waterproof gear guide will lead you to it.
Water-Resistant vs. Waterproof
Most outerwear fabrics withstand at least some exposure to water. Water-repellent and water-resistant fabrics provide limited protection from precipitation, but they can't stand up to extended exposure to moisture without becoming saturated. To be categorized as truly waterproof, a fabric must provide a high level of sustained water protection during the harshest conditions. Sierra Trading Post includes "waterproof" in the description of only genuinely waterproof products with waterproof membranes and sealed seams.
In a laboratory setting, the more effectively a fabric resists the entry of moisture under pressure, the higher its waterproof rating will be. Waterproof ratings are measured in two ways, both related to maximum water-pressure resistance:
pounds per square inch (psi)
mm/24 hours
A "mm/24 hours" rating refers to the amount of rainfall a fabric can withstand in a single day. Thus a 10,000 mm waterproof rating means the garment can withstand over 32 feet (10,000 mm) of rainfall in a single day without letting moisture in. For either rating, the higher the number, the more waterproof the item will be. For example, a fabric labeled to resist 5 psi of water pressure without leaking is not as waterproof as a fabric that resists 10 psi of water pressure; a fabric with a waterproof rating of 10,000 mm is more waterproof than a 5,000 mm fabric.
Commonly used water-resistant fabrics withstand between 3 to 5 psi of water pressure, which is fine for a short, light rainfall (which only generates 2 psi of water pressure). Completely waterproof fabrics like Gore-Tex® withstand about 40 psi of water pressure, though. This extremely high rating becomes necessary if you are kneeling on wet ground or carrying a heavy pack, since the added pressure on the fabric significantly increases the permeability to outside moisture.
Tiny pinprick holes in the seams and stitching can compromise a garment's waterproofness, so completely waterproof gear must feature sealed, taped or welded seams that close up these holes so even a small amount of moisture won't be able to penetrate. Also, zippers must be welded or have storm flaps to prevent the entry of water.
How Waterproofing Works
There are two types of waterproof fabrics -- waterproof breathable and waterproof non-breathable. Waterproof, non-breathable fabrics are most commonly used for low-intensity activities in extreme weather conditions. (Examples include ponchos, rain suits and some hunting outerwear.) Waterproof, non-breathable garments offer the ultimate in moisture protection and are less expensive than waterproof breathable outerwear. This outerwear is similar to the old-fashioned rain gear your parents grew up with.
Waterproof breathable fabric (with breathability measured in "g/m²/24 hours") lets moist air pass through the material from the inside out only, making it appropriate for the widest range of activities and weather conditions. Waterproof breathable fabric is used in the construction of a variety of garments from technical parkas for skiing and mountaineering to simpler garments for backpacking and cycling. The higher the breathability rating, the more breathable the fabric.
At the heart of most waterproof breathable fabrics is a membrane that contains millions of microscopic "pores" per square inch. These pores can be up to 20,000 times smaller than a water droplet, but are much larger than water vapor molecules. This pore size allows the membrane to be completely waterproof from the outside while still allowing moisture to escape from the inside, making the garment breathable. Additionally, an oleophobic (oil-resistant) material is integrated into the membrane, preventing the penetration of body oils and other oily substances, like insect repellent, that can break down the membrane over time.
How Waterproof Breathable Fabrics Work
The waterproof breathable membrane is then laminated to the inside surface of high-performance fabrics like nylon and polyester to create waterproof breathable clothing, boots, gloves and hats.
For absolute waterproofness, outdoor gear, shoes and outerwear are often coated with a durable water repellent (DWR) treatment. DWR finishes cause moisture to bead up and roll off the garment so the surface remains dry enough for perspiration and body heat to pass through from the inside.
