Sinner began wearing it due to an injury he picked up during his successful Wimbledon campaign.
“The elbow is good,” the 23-year-old told a news conference at the Cincinnati Open after a training session on Wednesday.
“Today was the first time that I put a sleeve on because I liked the feeling of the sleeve.
“It gives a little bit more impact with the ball, it’s slightly more stable.
“That’s my point of view and I liked it in Wimbledon.
“I have to see how it is when it’s very hot and humid, because it’s a little bit different, so it’s going to be something that I’m going to take into consideration.
“But I really love the feeling it gives of pure striking.”
Sinner is the defending champion in Cincinnati and will face Vit Kopriva or a qualifier in his opening match.
