I am a tall guy (6'5")with broad shoulders, wide chest and thick muscled thighs-----but also I have a spare tire waist. I've worked out endlessly in gyms and still can't get rid of it. Finally, on the advice of a buddy of mine, I tried the Manshape Support Brief. It is fantastic and comfortable. The minute I slipped this puppy on, I felt my posture go straight and my belly go flat. The no-roll waistband is a great innovation, so there is no constant rollover from sitting down, standing up, sitting back down, etc. The Manshape design is clever and people will notice the change when I wear it, especially with fitted shirts and pants. Even my pre-teen kids tell me I look slimmer and better. Manshape is one of the best buys I have made in a long time....and it is made in the good ol' USA!
