I bought this for my grown son. When he was younger he had great posture. But as he got older he started to walk on his tiptoes which threw his back and neck forward, making it look like he was slouching. He isn’t very tall so there is no reason for him to slouch. The corrector is made of comfortable, breathable material. He was able to easily put it on and adjust it to his size. He can wear it under his clothes so it is not visible or noticeable to anyone. He says it does pull his upper frame up straight and reminds him to walk flat footed instead of on his tiptoes. He doesn’t wear it all day...he started slow and has worked up to 2-3 hours per day. He’s found that it helps him when he is sitting at his desk, slouching over his laptop. The corrector helps keep his neck and shoulders in a more natural position that helps his posture. This seems to be a good product. It isn’t a cure, but it can help occasionally. It floods durable enough that he can wear it when he needs to and then store away and if he needs to pull it out and use it again.
