The pros and cons of microfiber underwear usually focus on fit, fabric, and performance. Underwear in this category is usually very breathable and wicks moisture away quickly, which can make it a good choice for sports or working out. Many people also find it comfortable. Microfiber may be somewhat thick, however, which means that is isn’t always the best choice for wearing under tight-fitting or otherwise figure-hugging clothes. It is typically made entirely of synthetic materials, too. People with skin sensitivities may be better off sticking with cotton or other natural fibers, and individuals concerned about the environmental impacts of synthetic manufacturing sometimes stick to clothes made in a more eco-friendly way.
The term “microfiber” is somewhat broad, but in the underwear context it typically indicates that the garment is soft and highly breathable. The yarns and threads used to weave these types of fabrics tend to be designed for performance, and often allow for good airflow. This means that people wearing them stay cool even in warm climates, or while exercising or engaging in other strenuous activity.
Most of the time, the fabric fibers also repel water. This is usually by design, but is also sometimes a factor of the threads’ chemical structure. Unlike cotton or other plant-based fibers, the majority of which absorb moisture, most synthetic strands push water molecules away. As a result, microfiber underwear tends to repel sweat and other moisture, leaving the skin in the sensitive genital and groin region dry. These wicking properties tend to reduce odors, too, since many of the smells that build up in cotton or other underwear are related to bacteria that thrive in moist, wet environments.
These water-repellant characteristics also mean that the material dries relatively quickly after washing. Travelers often find this helpful when doing laundry on the go, and it also saves energy when it comes to using electric clothes driers. In most cases, the garments will drip-dry in as little as an hour.
The comfort of micofiber underwear can be either a pro or a con, depending on the audience. Many people find this sort of garment to be very comfortable because of its sleek, cool feel, while others find its slickness somewhat unpleasant. Most underwear in this category is very smooth, sometimes to the point of being almost slippery to the touch.
Much of the debate relates to cut and style. Underwear that is too loose, too tight, or poorly fitting may be uncomfortable no matter the material, and whether microfiber is a pleasant fabric often has to do with individual taste.
Visibility and Layering
It is often the case that this sort of underwear is thicker than cotton or other alternatives, which can be a pro or a con depending on the context. People who are looking for undergarments that provide shaping and support often find the bulk to be helpful, but it can also make lines and contours more visible under tightly-fitting clothes.
Concerns Over Fiber and Manufacturing
Some people choose not to use underwear made of microfiber because they prefer more natural products, whether for personal or ethical reasons. People with skin sensitivities or allergies to various plastic or other polyester compounds are usually best served looking for cotton or linen-based materials, since plant particles aren’t as likely to trigger reactions.
The micofiber manufacturing process almost always uses a variety of chemicals to both produce the yarns and fuse them together. People who are concerned about the environmental impact of these reactions, whether it be from possible run-off to the mining of fossil fuels, often shy away from microfiber products unless they are made by companies that certify their processes as “green” or environmentally-friendly.
