The Secret of Athletic Clothing - It’s not what you think
As the founder of The Mobility Clinic, I don’t have much experience on athletic clothing in the sense of specific material quality and the inner chemistry that goes with it. You buy it from an expensive (or not) clothing company and wear it (even with minor flaws) because that is how society runs for us. We all think that the more expensive something is, the better luxury and quality right? After researching more about clothing, athletic performance, and the material for mobility, here’s what I found out based on multiple different sources. You’ll be seeing all information in just one blog, you’re welcome 🙂.
The reason why I decided to make this blog is to educate individuals about activewear clothing because it directly goes toward the mobility and movement of the body. Depending on the physical activity you are doing, you must find the appropriate piece of clothing associated with that. Look at factors such as armholes, weight, and the “stretch” of the material. Most importantly, breathability is also important as well. High cardio workouts must need more breathability to exit the heat produced by the body. Along with breathability, making sure that the material doesn’t chafe over the skin (especially sports like cross country, track, other running sports). Figuring out how these factors apply to your activity is super important; it’ll help you to feel more confident every step of the way overall helping your mobility of body and not feeling restricted.
Most huge clothing companies don’t focus on the actual piece of clothing and the tactics of it. They want their products to get more popular and when social media platforms see the “trendiness” with the clothes, more people start buying it just for the fame and price tag of $100. However, people will start complaining about the negatives of the material because they realize that it’s not worth the price. The truth is, that they care about the brand’s name than the quality of clothing. In obviousness, if cheap material is being used, then overall it is going to be a lot less durable and cheaper in price, but because of the brand name it can be on the market for $50 or it can be cheaper ($20). It overall depends on the luxury of the brand and what their expenses are and other aspects as such. Note that this may not go to all brands, but it definitely does to some.
Shift Fashion Group, a business that digs deep into clothes and examines it, compared Lululemon Align Leggings (which they rated overall a 7/10) to “dupes”. They use tests such as water retainment, thickness of fabric, signs of pilling, weight of fabric (in GSM - grams per square meter), and they also have a graph showing displacement vs compression.
After seeing that one legging “dupe” was able to absorb water (took some time) the clothes person said that, “… in terms of its compression, you’ll notice here it ramps up much quicker, meaning that the moment you’re starting to stretch, it will start feeling tighter faster. And that’s because this is a single jersey knit, it’s not an interlock knit like the rest of the leggings” (Joe). Understanding this information can help to see that choosing the right legging for your specific physical activity can be “performance-changining” and help you the most rather than just prestige.
The brand of the leggings that were the closest to Lululemon was CRZ yoga; however, even though the first impression is going to feel the same, later on there’s going to be a difference between both leggings and you’ll be able to feel those differences over time. Price and cost are two different topics. Price is the amount the producer is asking you to pay for and cost is how much money it takes to make that piece of clothing. In terms of branded clothing, it does go a long way. The price for Lululemon Align Leggings are $98; however, with the fabric style quality, color and other clothing aspects even as simple as the tag, it can take about $10-14 just to make one. Again as said, the reason for this is just just because of the “premium” the specific brand name. There are many stores and shops that are also the same as well.
The chemistry of all different types of clothes consists of fiber fabrics such as cotton, polyester, nylon, spandex, and more. These types of fibers are called polymers, which are woven into the fabrics. With this kind of chemistry, we’re glad to have socks that don’t lose shape, dry sportswear, and great gear for mobility and stretching.
The process starts off as a textile of a molecular structure. Specific polymers, such as cotton, go through many treatments to get the material strong and have better dye uptake. Different processes can also vary depending on the polymer, such as polyester. Later, they combine the two stronger polymers together to create the texture that makes the textures.
“From stretch leggings to waterproof jackets, performance clothing is defined by its chemistry. Elastane fibres, (commonly known by brand names like Lycra or Spandex) provide stretch through their coiled polymer chains, which can extend and return to shape repeatedly without damage.
Waterproof and breathable fabrics are even more chemically sophisticated. Technologies like Gore-Tex use microporous membranes made from expanded PTFE (polytetrafluoroethylene), which have pores small enough to block water droplets but large enough to allow water vapour to escape. Hydrophilic coatings, another method, absorb moisture and move it across the fabric surface by diffusion” (Brady).
You can see the relations here, that finding the correct clothing is more important about going to a quality place that reflects your physical activity and preference. Each person can find their own brand of activewear that they find the most fitting based on the chemistry of the fabric to the overall durability and qualities each unique piece of clothing displays.
And that, my friend, concludes another blog from The Mobility Clinic.
