Product Name: Support Jacket Bb+AIr lite U.P.R. Co., Ltd. Purchased at Workman in 2025 Reduces maximum muscle strain by 40% when worn (According to our research) I tried it on about 3 times, but haven't used it. I am selling it because I don't plan to use it in the future. Those with lower back pain might find it worth trying. From the website: Effects on various tasks: Weeding Reduces muscle strain by up to 14%* Bending over Reduces muscle strain by up to 28%* Shoulder carrying Reduces muscle strain by up to 61%* Shoveling Reduces muscle strain by up to 77%* The QR code on the back of the package also provides a video demonstrating how to wear it. It's easy to put on, but be careful as you can also put it on incorrectly. I hope someone will use it. Feel free to comment.
