i've got the socks and the full length top.
i trained all season for RL in them and it helped me warm up quicker and stay warm (also you don't seem to get as cold when you warm down either).
it somehow helps with moisture/sweat (keeps you dryer) too.
i also used both the socks & top during the games until i was told the long sleve tops were banned. but the socks seemed to stop my late match cramping! i ended up wearing the socks under my footy sock all year!
TBH i've never really used them to 'recover' as such, more when i'm competing or training.
but i rate them highly.
getting the bike shorts soon, expensive but worth it if you're serious about your sport.
i also have the 'BSC' branded compression clothes, told it does the same job and skins brand and its usually a bit cheaper. also BSC sponsors manly too
