No brand product. This is an item purchased from overseas online shopping. The feel and thickness were good, but the hem length was a bit short, and I personally found it difficult to wear, so I'm putting it up for sale. I've only worn it 1-2 times, and about 2 out of the 4 pieces haven't been worn at all. The thickness is such that you could wear it as an inner layer in winter, but it's not as warm as Heattech. It's a thickness that seems wearable in early spring and early autumn. Size S. The hem length is short for a 160cm tall person of average build. The sleeve length seems perfect. Please note that there may be minor dust due to home storage. I will take waterproof measures, put two pieces in an OPP bag each, and ship via Yu-Packet Post.
