I have been using jockeys cotton pajamas, tee-shirt and it is very comfortable. I have one gym wear and I have been using that for last 2 years, it still very comfortable and durable. I bought jockey wear from jockey stores, staff is polite and attend customers beautifully as I observed.
Once I visited the store and my required product was sold and the owner was there, he listened by the query and on the spot called their dealer and ordered that product and provided me within 7 days.
