I am a user of Jockey Products for over 8 years now. I have been using their sportswear, nightwear, T-shirts, Boxers, socks, innerwear till now.
They are the most comfortable innerwear of all other brands according to me.
The quality of their T-Shirts and shorts are damn good. They absorb the sweat and keep you from being irritated. They are durable even after rough and tough usage.
Their socks are simply superb because of the extra layer of wool type fabric under the feet which keeps you from sweating, which helps in avoiding bad smells after removing the socks in a room.
They are the one for me and I will always be using their products untill I come across something even better than them, which is not likely to happen ; ).
