I got this bad boy for my daily tube rides in London, and let me tell you, it's a game-changer! My back feels so much better and I walk taller now. The adjustable straps make it super comfy, and I love that I can wear it under my clothes without anyone noticing. Only thing is, I wish it came in more colors, but hey, can't have it all, right? Overall, super happy with it!! 🙌
