I spend about two hours in at the gym .... I do anything from weight lifting to military style workouts and they are so comfortable. I would recommend these to ANYONE no matter what you are doing throughout your day. Think they are HOT? NOPE... I spend about 20 mins in the sauna and steam rooms with these and once again.. they are comfortable. Anyways.... More simple terms: FIVE STARS and High recommendations . Thank you Rothco I will be purchasing more..
