Comfortable, accurate fit, very breathable, and soft.
Best singlet I have ever owned. Very light weight and good for heavy sweating. 5'9" 170lbs and got a large, solid fit, I like space in singlet, but could have gone medium.
I got this singlet for running a marathon. I read the reviews and still decided it was worth a try. It is sheer but does not show any skin through. It was a cold marathon (38F) so this was chilly to run in for the first 30 mins until it warmed up. It is very lightweight and comfortable. It held up super well and even worked out great branding it with some DTF graphics.
Fits perfectly and so light! Great to work in!
Very comfortable and lightweight, allowing freedom of movement. The fabric looks and feels premium. I have no complaints about the size. It would be perfect if it were a little cheaper, but quality comes at a price.
This is a great value: comfortable, durable, and ideal for active use.
