BB and Mullins
Go to golflocker.com. They have all the new line of products, and their prices are quite good. I have gotten a fair amount of pants/shorts from them. Seems to be a solid on line retailer.
And mac..... I must chastise you sir. You ask," are they better than other brands?" Surely you jest sir! I have worn every brand out there and for performance golf apparel, nothing even comes close. The fabric is perfectly weighted for warm or cool conditions. They don't wrinkle, and I have even worn them in cramped airplanes (see my many posts). They are stylish and don't make you look foolish (see PUMA). And they are high quality fabric that will hold up on course.
Go get you some my friend!
