Many, many thanks for the feedback.
Seems like that WalMart price is 1/3 the price of Under Armor prices I've seen, and about the same of lycra diving rash guards.
A couple of people don't like the tight fit design - Spooky is your reason for not liking them the same as bjjprim8's?
Also, something I wonder about as a noob to BJJ, is there a downside to wearing a rashguard, in terms of it making it harder for your training partners to control you (i.e. therefore making it less necessary for the wearer to learn better techniques against the opponent's hand and skin grip)? I guess this is sort of a question for instructors. I don't mind the difficulty of dealing with more advanced training partners controlling me; just want to avoid the flesh damage.
Maybe there are other ways of avoiding the abrasion bruises, as well, other than whining and screaming in pain alot?
