What a great find - I had never heard of Deminpro before and am very glad I found it on ebay. My husband put the shirt on and fell in love with it immediately. The material is soft, breathable and feels comfortable. It also stretches a bit, which is a very nice feature. Since my husband is losing more and more weight, we will go back to smaller sizes. The material washes well and dries crease-free if left in the dryer for some time. No wrinkles even after wearing all day. HOORAY!
