When I wore MUJI's "Men's Organic Cotton Mix Heat Generating V Neck Long Sleeves T-Shirt" as a nightgown last night, I experienced sudden and severe itching. This was presumably due to the thermal storage function of the product, which contributed to the increase in body temperature. I therefore prohibit the wearing of all thermal storage underwear, including the product in question, at bedtime and freeze indefinitely any plans to purchase more of the product in question (17:12, 22/11/2021)
>>128 I think it will function properly as a nightgown only under unheated conditions below 10 degrees Celsius.
