I love these vest, great for workouts and also if you do a lot of running around at work like i do, its great for work as well. Im giving this a 4 star rating only because it rises up a lot with a lot of movement but it isn't too bad. Im guessing most products like this do and it does help if you have a lot of bottom as well. I also have a bit of a gut so i wore an extra waist band with it just the regular sweat band that don't cost much just to make sure my whole mid section was covered and would sweat. I also like that i can use this to keep my extra love handles from moving too much while Im doing intense workouts lol Im 5,6 i was at 258 when i ordered so i got a 3x but found that it fit but i could go smaller for a tighter fit and i ordered a 2x which fits better but i still where both. The 3x i use when doing intense workouts for a little more room and the 2x i wear for jogging, light workouts and at work. The green Im wearing is a 3x
