Anyone Use Compression Underwear?

Does anyone use compression underwear under their gi?



I sweat quite a bit during training and notice I get a bit stinky. Whilst looking for heat tranferring technical underwear, I spotted lots of compression garments which I usually associate with rugby / soccer / tennis.



The "compression" part of the title would suggest to me they could be restrictive when performing some movements?



Any experiences? Do they actually speed up recovery?
