I'm 5'10, 230# and actively losing weight. However, I needed something to gain belly fat until my fitness regime took care of it. I bought this Under Armor compression shirt to wear under a shirt and it fits perfectly. I bought the size XL with undershirts as usual and the compression ratio is strong enough to keep the bowels in check while still being comfortable enough to wear all day. I wash them at a normal load with my other clothes and tumble dry on medium heat. and they have held up very well. Now I have 5 of these for a week. One caveat mentioned in my title, the edges of the inseam will irritate you due to the shirt's tight fit. This was an armpit issue for me and as another reviewer mentioned, the workaround is to wear the shirt inside out. Since I wear this under my clothes, it's not a deal breaker.
