Does Uniqlo’s Heattech Actually Work?

The winter season often has us rummaging through our wardrobes in search of warm clothes. This is where Heattech comes in, Uniqlo’s cutting-edge insulating garment technology, designed to offer warmth without bulk. But does it stand up against traditional thermal wear? Let’s find out.

According to Uniqlo, Heattech is made using “high-quality polyester blends, acrylic, and rayon”. This special combination apparently does more than just cover – it actively warms you up. Uniqlo claims that the material captures the body’s moisture, transforms this kinetic energy into heat, and then retains this warmth thanks to air pockets in the ultra-thin fibers.

For varying degrees of cold, Uniqlo offers the Heattech range in three warmth levels: regular, extra-warm, and ultra-warm. Here are the upsides and downsides of this garment technology:

Advantages of Heattech

  1. Ease of maintenance: One of Heattech’s most prominent features is that it’s user-friendly in terms of maintenance. They are easy to wash, which is an advantage when you’re wearing them frequently during cold months.
  2. Comfy and affordable: Often, artificial fiber clothes can be scratchy and uncomfortable. Not Heattech. They offer a level of comfort that surpasses many other synthetic garments, and without breaking the bank.
  3. Perfect for at night: If you’re the type to feel cold easily, slipping into Heattech before bed might just guarantee you a night of undisturbed slumber.
  4. Versatility: This is where Uniqlo’s offering truly shines. The variety in the Heattech range means you can either sport them on their own or wear them as a base layer beneath your regular clothes, making them an adaptable piece in your winter wardrobe.

Disadvantages of Heattech

  1. Overheating: While designed for cold environments, in milder conditions, you might find yourself feeling a bit too hot at times when wearing Heattech.
  2. Comparing with traditional thermals: Heattech is not necessarily superior. Traditional thermals, especially wool-based ones, have been time-tested and have their own set of advantages, such as natural moisture-wicking properties.
  3. Not ideal for workouts: If you’re thinking of using Heattech for your winter workout, you might want to reconsider. They tend to trap moisture, making them less suitable for activities that result in a lot of sweating. Moreover, they’re slow to dry, which could leave you in damp clothing for longer than is comfortable.

Heattech by Uniqlo offers an innovative take on winter wear, prioritizing warmth without the need for bulk. It’s versatile, comfortable, and affordable. However, when deciding between Heattech and traditional thermal wear, it really boils down to personal preference and the specific conditions you’ll be using them in.

For everyday use and milder winter days, Heattech could be an excellent addition to your wardrobe. But for intense cold or physical activity, it might be wise to stick with traditional thermal wear or at least ensure you’re layering appropriately.
