I started jogging 8 weeks before.
My brother is in the army, so he is used to the cold.
The first time I thought I einfriere because it had only -1.5 °.
I am immediately afterwards to Amazon pure and have ordered these undergarments.
As it was not very expensive I thought that it was not so hot holding as expensive,
but this is not the case.
Week after we are gone back up and running (the underwear was the next day already there) and see
because, my true not cold temperature was approximately at 0 - 0.5 ° my whole body was very warm even after the 6.5km yet.
So I can only recommend the underwear.
