I really like Peak Velocity clothing. Their products are always made from the highest quality materials and fit well. This novel jacquard muscle t-shirt is one such garment. I had to look up the word "jacquard" and found out that jacquard has a pattern woven into the material, not drawn or sewn. This gives the shirt a certain lift. The material is soft and comfortable and very cool in the summer heat. The t-shirt is 100% polyester and is machine washable in warm water with the same colors, using only non-chlorine bleach when needed. It should be tumble dried on a low setting, ironed with a cold iron and never dry cleaned. This t-shirt is great for showing off a muscular physique and looks great if you've got the physique for it. In fact, I'm sure it would look good even on someone who doesn't have bulging arm muscles, but it really is built to show off good biceps. All in all, this is a beautiful dress. Well done, it comes highly recommended and easily deserves five stars.
