Nothing like being able to rinse a shirt in water and have it dry in minutes while in the winter having an extra layer of warmth for only a Jackson (not Michael, but the president).
Is UNIQLO HEATTECH and AIRism just marketing BS or is it the real deal? That is what I wanted to know even after my own experiences which are great although maybe I am sucka for their hype? Well, time to find out.
I’m Basic AF
The items I have purchased are the essentials, such as socks, t-shirts in the summer (AIRism), and long underwear during the winter (HEATTECH). Although, I do own a coat and several UNIQLO wool sweaters, but the bulk of what I wear is on par with the variety of Homer Simpsons wardrobe.
I Know Nothing About Fashion or Being Fashionable
As always, I start off with what I know which is not much, but I do know how to stay warm during the winter and cool during the summer. I also think I can do a better job at communicating why you want to buy AIRism and HEATTECH products. NOTE: I do not make a single cent directly off of the content below, so the links provided are attempts to help you deliberate on the quality and value of UNIQLO products.
Cold Weather (HEATTECH – 3 LEVELS)
HEATTECH is made from bio-warming material that converts body moisture into heat, keeping you comfortable all winter.

Hot Weather (AIRISM)
- As a sweat-wicking inner layer
- As quick-drying activewear
- As breathable styles in the summer heat
- As loungewear that stays cool to the touch

Quick-Drying and Breathable
AIRism dries more quickly than cotton due to the capillary phenomenon that disperses liquid throughout the garment helping it to evaporate.
Their corresponding video likens their product to silk (AIRism and silk have a very fine weave), but they saying nothing of the stretching characteristics.
Anti-microbial and self-deodorizing
When compared to cotton, their video demonstrates that it neutralizes sources of odors such as ammonia, acetic acid, nonenal, and isovaleric acid, “so you don’t need to worry about odors.”
UNIQLO has two points that address odor: 1. anti-microbial and self deodorizing and 2. absorbs, neutralizes, and eliminates sources of odor in clothing.
Stays Cool to the Touch
What the?! “AIRism is made from fibers that absorb water vapor better than ordinary polyester, so even if you sweat, it keeps you feeling fresh.” So AIRism is a type of polyester? (why yes it is, “88% Polyester, 12% Spandex” but they also offer AIRism cotton).
AIRism Cotton (if a polyester blend isn’t your thing)
- 71% Cotton, 25% Polyester, 4% Spandex
- Machine wash cold, gentle cycle

Every manufacturer markets their polyester and material blends as an odor control feature which seems somewhat common.
Now, I Am Wondering if All Polyester Is the Same
Unfortunately, I did not find much information on how much polyesters vary, but I did find the companies that UNIQLO partner with which is Asahi KASEI and Toray Industries. The two companies are the ones that give UNIQLO their technological edge (Cupro, HEATTECH, AIRism and maybe possibly BLOCKTECH, DRY-EX, and UV protection?).
A chemical and material science company which was founded in 1931.
Manufacturing, processing and sales of the following products, among others: fibers and textiles, performance chemicals, carbon fiber composite materials, environment and engineering, life science, and others.
Here Are a Few Other Things You Should Know About Polyester
