Towards the end of 2014 I had been inspired by my friend Kevin in Michigan to wear an Under Armour shirt as sleepwear, an idea I was happy with. Since then I slept in my size Small Under Armour shirts most of the time. But in the beginning of 2018 I noticed that while I normally had to get up at 5 am for my nightly pee I had to get up 2-3 hours earlier in wintertime.
