My love of Uniqlo's Heat Tech
I was already familiar with Uniqlo's Heattech early on in my Japan years, but my real appreciation for it came during a monitor tour trip to Monbetsu in Hokkaido. The temperature dropped to a pretty brutal -17°C, but I remember being pleasantly surprised that I wasn't anywhere near as cold as I'd expected. As it turns out, a few layers of Heattech really do make a difference!
I think what I love about it most is that you don't need to go outside looking like the Michelin (Wo)Man to stay warm. A couple of lightweight layers underneath your regular clothes can make a massive difference.

Heattech saved the day on this trip to Monbetsu in Hokkaido, under my regular wear. As you can probably ascertain from all that sea ice, it was pretty cold outside!
There are different warmth levels available, too, including the regular Heattech, Extra Warm and Ultra Warm ranges, so you can choose depending on the weather and how much time you'll be spending outside.
It's one of those everyday Japanese inventions that I initially thought was a bit of a gimmick, but it has proven itself time and time again!! Highly recommend it if you're in a colder climate, going on a ski trip, or just want to be a bit more snuggly in your day to day life!

I didn't know about the different levels :-o And always good to hear when something truly "does exactly what it says on the tin" so to speak!
