Where to find TALL size golf-wear? in Fashion & Style Posted September 12, 2019 There is all sorts of companies who have tall options, and range in prices. My go to lately have been Under Armor and Old Navy. Under Armor for name brand, and Old Navy for price. Old navy has polos and their pants and shorts -although the old navy pants say slim fit - I am 6'9" and about 300 pounds and order my normal size pants and they fit perfectly.
