Its very comfortable. I can keep it on for hours. I have notice a tremendous reduction in my tummy since wearing this splint. I was already doing the exercises but this just expedited my results after only 2 weeks. I ordered this as a last ditch effort to stop looking 6 months pregnant. I am very petite (size 4) and no stretch marks. As an amateur bodybuilder, Ive had 6-pk abs forever until my pregnancy. I can actually see my 6-pk trying to make an appearance again. With my continued healthy diet, exercise and FITSplint,I believe in about 2 more months I will be back to my post mommy body. I'm stoked!!! Thank you Mombodfitness for FITSplint!
