A storm-flap is a protective covering found on various types of clothing, bags, and other outdoor gear. It is designed to provide an additional layer of protection against harsh weather conditions, particularly wind and rain. Typically, a storm-flap is made of a water-resistant or waterproof material, such as Gore-Tex or similar synthetic fabrics.
The primary purpose of a storm-flap is to prevent moisture from penetrating through the openings in the garment, such as the zipper or buttons. Without a storm-flap, rain and wind can enter through these openings, making the wearer cold and wet. This can be especially dangerous in colder climates, where hypothermia can set in quickly.
Storm-flaps come in various sizes and shapes depending on the item they are designed to protect. For example, a backpack may have a small storm-flap covering the zipper, while a winter coat may have a larger, more substantial storm-flap that covers the entire front of the coat.
In addition to protecting against moisture, storm-flaps can also help to provide insulation against the cold. By covering the openings in the garment, the storm-flap can help to trap heat and prevent it from escaping. This can be particularly beneficial in colder climates where warmth is crucial.
There are different types of storm-flaps, with some being more effective than others. A single storm-flap is the most basic type and consists of a single layer of material covering the opening. While it provides some protection against the elements, it may not be as effective as a double storm-flap or a bi-swing back storm-flap.
A double storm-flap consists of two layers of material covering the opening, with one layer overlapping the other. This design helps to prevent moisture from seeping through the opening, even in heavy rain or wind. A bi-swing back storm-flap is designed to provide additional flexibility and range of motion, allowing the wearer to move more freely without compromising protection.
In addition to protecting against the weather, storm-flaps can also be stylish. Many high-end outdoor gear brands incorporate storm-flaps into their designs, with the flap adding a distinctive look to the garment. Some designers even incorporate contrasting colors or patterns into the storm-flap, creating a unique and eye-catching feature.
In summary, a storm-flap is a protective covering found on various types of clothing, bags, and other outdoor gear. Its primary purpose is to provide an additional layer of protection against harsh weather conditions, particularly wind and rain. By covering the openings in the garment, a storm-flap can prevent moisture from penetrating and help to provide insulation against the cold. There are different types of storm-flaps available, each with its own unique benefits and features. Overall, a storm-flap is an essential feature for anyone who spends time outdoors and wants to stay warm and dry in inclement weather.
