I have been wearing these tops since November 2022, for a 74 year old my back is already a lot better, I appreciate the improvement, tips on how to wear them, I've even taken up maintenance gymnastics again, I've already got two and I'd recommend two more in the next few months, don't say it's not effective, be patient, medication doesn't work immediately either, I'm an example of that, so be patient, thanks Percko

I'm still very pleased with the shirt, which supports my back and shoulders while I work. It has allowed me to restart the work that I had difficulty doing.

Marie Triart

I am very pleased with my Lyne Up purchase, I feel like my back pain is really improving. I was only able to buy one, I hope it doesn't loosen up over time

Rebecca

I used to stand awkwardly, always slightly bent over in front of the sink or worktop. The Percko shirt helped me to correct these bad habits, which really helped my back pain. I am very satisfied.

Michael Pavy

I received the shirts 15 days ago, and we can both see a clear improvement in our posture, I no longer slouch...my husband, who has a really stooped back, is gradually straightening up! Great discovery, I was sceptical though!

The effectiveness of the Percko top is not clear in the early days. It takes a few days to realise how useful it is. You have to keep using it and then after a while, you realise that you have unconsciously changed your postural habits thanks to the T-shirt.

Francine Byll

Hello, I have been feeling great relief for the past couple of weeks using the top. I stand up straighter.

Mark Blay

This is the second shirt I have bought for my family and they are very happy with it, so it comes highly recommended.
