Hi Summer
I have the Amoena Balance Delta (a partial) .......I had a mastectomy with implant recon but due to bad contracture I have now had a smaller implant put in & I am quite lopsided so have the prosthesis. It is silicone & I have it directly on my skin in my normal everyday underwired bra. I doesn't move around it is comfortable & not hot. I must say I didn't have it when I had the worst of my hot flushes but I will say I do feel heat/humidity a great deal & I haven't had any problems with the prosthesis........that breast doesn't sweat anymore !!!!!! I don't know why but that is the honest truth !. I am using my older smaller one (same type) as my swimming one. I sewed some pockets in my tank tops & just rinse it afterwards.
You can have a look at them on the internet.
Here in Canberra we have a little store who fit them by appointment & they were great (under $150.00 for the partial) & I got it all back from medicare.
Best of luck
